WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm:
85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke
/CO
Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du
racell MN1500
. These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.

WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke
/CO
Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du
racell MN1500
. These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.

WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke
/CO
Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du
racell MN1500
. These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the

You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.

To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.
