INSTALLATION
WHERE TO INSTALL CO ALARMS
T
he National Fire Protection Association (NFPA) recommends that a CO
A
larm should be centrally located outside of each separate sleeping
a
rea in the immediate vicinity of the bedrooms. For added protection,
i
nstall additional CO Alarms in each separate bedroom, and on every
l
evel of your home.
If your bedroom hallway is longer than 40 feet (12 meters), install a CO
Alarm at BOTH ends of the hallway.
In a Single-level Home:
• Install at least one CO Alarm near or within each separate sleeping
area.
• For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
I
n a Multi-level Home:
•
Install at least one CO Alarm near or within each separate sleeping
a
rea.
• For added protection, install at least one CO Alarm on each level of
the home.
• For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
I
n Mobile Homes:
•
Install CO Alarms on inside walls ONLY. Uninsulated outside walls
a
nd roofs of mobile homes often transfer heat and cold from out-
d
oors. The Alarm should be located at least 6 inches (152 mm)
f
rom all exterior walls and at least 12 inches (305 mm) from supply
o
r return vents.
WHERE CO ALARMS SHOULD NOT BE
INSTALLED
DO NOT LOCATE THIS CO ALARM:
•
In garages, kitchens, furnace rooms, or in any extremely dusty, dirty
o
r greasy areas.
•
Closer than 20 feet (6 meters) from a furnace or other fuel burning
h
eat source, or fuel burning appliances like a water heater.
• Within 5 feet (1.5 meters) of any cooking appliance.
• In extremely humid areas. This alarm should be at least 10 feet
(3 meters) from a bath or shower, sauna, humidifier, vaporizer, dish-
washer, laundry room, utility room or other source of high humidity.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include unconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In turbulent air, like near ceiling fans, heat vents, air conditioners,
fresh air returns, or open windows. Blowing air may prevent CO
from reaching the sensors.
• Outside the Mobile Home.
• In direct sunlight.
• This CO Alarm is designed for use inside a single-family
home or apartment. It is not meant to be used in common
lobbies, hallways, or basements of multi-family buildings
unless working CO Alarms are also installed in each family
living unit. CO Alarms in common areas may not be heard
from inside individual family living units.
• This CO Alarm alone is not a suitable substitute for complete
detection systems in places which house many people, like
hotels or dormitories, unless a CO Alarm is also placed in
each unit.
• DO NOT use this CO Alarm in warehouses, industrial or
commercial buildings, special-purpose non-residential build-
ings, or airplanes. This CO Alarm is specifically designed for
residential use, and may not provide adequate protection in
non-residential applications.
C
O ALARM

HOW YOUR CO ALARM WORKS
GENERAL INFORMATION
• This CO Alarm does not operate without working batteries.
Removing the batteries, or failure to replace them at the end
of their service life, removes your protection.
A CO Alarm measures the CO levels in the air. It will alarm if CO levels
rise quickly (if the heat exchanger on your furnace breaks, for example),
or if CO is consistently present (a slow CO leak on a fuel-burning
appliance).
This Carbon Monoxide Alarm features a permanently installed sensor
and an 85 dB alarm horn. It also has a silence feature to temporarily
quiet the alarm horn.

the battery is correctly installed, and test it again.
HOW TO INSTALL YOUR CO ALARM
Read “Where To Install Your CO Alarm” before starting.
Before you start installation, find the pair of self-adhesive labels
included with this CO Alarm. On each label write in the phone number
of your emergency responder (like 911) and a qualified appliance
technician. Place one label near the CO Alarm, and the other label
in the “fresh air” location you plan to go if the alarm sounds.
IF YOUR CO ALARM SOUNDS
A
ctuation of your CO Alarm indicates the presence of carbon
m
onoxide (CO) which can kill you. In other words, when your CO
A
larm sounds, you must not ignore it!
IF THE ALARM SIGNAL SOUNDS:
1
. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3
. Immediately move to fresh air—outdoors or by an open door or
w
indow. Do a head count to check that all persons are accounted
f
or. Do not re-enter the premises, or move away from the open door
o
r window until the emergency services responder has arrived, the
p
remises have been aired out, and your CO Alarm remains in its
n
ormal condition.
4
. After following steps 1-3, if your CO Alarm reactivates within a
2
4-hour period, repeat steps 1-3 and call a qualified appliance
t
echnician to investigate for sources of CO from fuel-burning
e
quipment and appliances, and inspect for proper operation of this
e
quipment. If problems are identified during this inspection have
t
he equipment serviced immediately. Note any combustion
e
quipment not inspected by the technician, and consult the
m
anufacturers’ instructions, or contact the manufacturers directly,
f
or more information about CO safety and this equipment. Make
s
ure that motor vehicles are not, and have not, been operating in
a
n attached garage or adjacent to the residence. Write down the
n
umber of a qualified appliance technician here:

___________________________________________________________
Alarms have various limitations. See "General Limitations of CO
Alarms" for details.
USING THE SILENCE FEATURE
• The Silence Feature is for your convenience only and will
not correct a CO problem. Always check your home for a
potential problem after any alarm. Failure to do so can result
in injury or death.
•
NEVER remove the batteries from your CO Alarm to silence
t
he horn. Use the silence feature. Removing the batteries
r
emoves your protection! See “If Your CO Alarm Sounds”
f
or details on responding to an alarm.
T
he Silence Feature is intended to temporarily silence your CO Alarm’s
a
larm horn while you correct the problem—it will not correct a CO
problem. While the alarm is silenced it will continue to monitor the air
for CO.
When CO reaches alarm levels the alarm will sound— repeating horn
pattern: 4 beeps, a pause, 4 beeps, etc. Press and hold the
Test/Silence button until the horn is silent. The initial Silence cycle will
last approximately 4 minutes.
NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates
present CO levels and responds accordingly. If CO levels remain
potentially dangerous—or start rising higher—the horn will start
sounding again.
While the detector is silenced:
If the CO Alarm...
Is silent for only 4 minutes,
then starts sounding loudly—
4 beeps, pause, 4 beeps,
pause
This means...
CO levels are still potentially
dangerous.
If the CO Alarm...
Remains silent after you
pressed the Test/Silence
button
This means...
CO levels are dropping.
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
C
O is an invisible, odorless, tasteless gas produced when fossil fuels
d
o not burn completely, or are exposed to heat (usually fire). Electrical
a
ppliances typically do not produce CO.
T
hese fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
k
erosene, 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.
E
xtreme Exposure:
C
onvulsions, unconsciousness, heart and lung failure. Exposure to
carbon monoxide can cause brain damage, death.
Some individuals are more sensitive to CO than others, including
people with cardiac or respiratory problems, infants, unborn babies,
pregnant mothers, or elderly people can be more quickly and
severely affected by CO. Members of sensitive populations should
consult their doctors for advice on taking additional precautions.
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.
HOW CAN I PROTECT MY FAMILY?
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 appli-
ances 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.
WHAT LEVELS OF CO CAUSE AN ALARM?
U
nderwriters Laboratories Inc. Standard UL2034 requires residential CO
A
larms to sound when exposed to levels of CO and exposure times as
d
escribed below. They are measured in parts per million (ppm) of CO
o
ver time (in minutes).
UL2034 Required Alarm Points*:
•
If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
B
ETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
B
ETWEEN 10 and 50 MINUTES.
•
If the alarm is exposed to 70 ppm of CO, IT MUST ALARM
B
ETWEEN 60 and 240 MINUTES.
*
Approximately 10% COHb exposure at levels of 10% to 95% Relative
H
umidity (RH). The unit is designed not to alarm when exposed to a
c
onstant level of 30 ppm for 30 days.
C
O Alarms are designed to alarm before there is an immediate life
t
hreat. 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
a
verage, healthy adults, but after 4 hours the same level may cause
h
eadaches.
•
An exposure to 400 ppm of CO may cause headaches in average,
h
ealthy adults after 35 minutes, but can cause death after 2 hours.
T
his CO Alarm measures exposure to CO over time. It alarms if CO
l
evels 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
s
ounds an alarm before the onset of symptoms in average, healthy
a
dults.
W
hy is this important? Because you need to be warned of a potential
C
O problem while you can still react in time. In many reported cases of
C
O exposure, victims may be aware that they are not feeling well, but
b
ecome disoriented and can no longer react well enough to exit the
b
uilding or get help. Also, young children and pets may be the first
a
ffected. The average healthy adult might not feel any symptoms when
t
he CO Alarm sounds. However, people with cardiac or respiratory prob-
l
ems, infants, unborn babies, pregnant mothers, or elderly people can be
m
ore quickly and severely affected by CO. If you experience even mild
s
ymptoms of CO poisoning, consult your doctor immediately!
S
tandards: Underwriters Laboratories Inc. Single and Multiple Station
c
arbon monoxide alarms UL2034.
A
ccording to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“
Carbon monoxide alarms covered by these requirements are intended
t
o respond to the presence of carbon monoxide from sources such as,
b
ut not limited to, exhaust from internal-combustion engines, abnormal
o
peration of fuel-fired appliances, and fireplaces. CO Alarms are intended
t
o alarm at carbon monoxide levels below those that could cause a loss
o
f ability to react to the dangers of Carbon Monoxide exposure.” This
C
O Alarm monitors the air at the Alarm, and is designed to alarm before
C
O levels become life threatening. This allows you precious time to
l
eave the house and correct the problem. This is only possible if Alarms
a
re located, installed, and maintained as described in this manual.
G
as Detection at Typical Temperature and Humidity Ranges: The CO
A

T
ESTING & MAINTENANCE
WEEKLY TESTING
• Test the CO Alarm once a week. If the CO Alarm ever fails to
test correctly, have it replaced immediately! If the CO Alarm is
not working properly, it cannot alert you to a problem.
• 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.
P
ush and hold the Test/Silence button on the cover until you hear an
a
cknowledge “chirp”. The alarm horn will sound 4 beeps, a pause, then
4
beeps. The ALARM (RED) light will flash.
T
he alarm sequence should last 5-6 seconds. If it does not alarm, make
s
ure fresh batteries are correctly installed, and test it again. If the unit
s
till does not alarm, replace it immediately.
I
f the alarm does not test properly:
1
. Make sure that fresh batteries are installed correctly.
2. Be sure the Alarm is clean and dust-free.
3. Install a fresh 9 volt battery* and test the Alarm again.
• DO NOT try fixing the Alarm yourself – this will void your war-
ranty! If the CO Alarm is still not operating properly, and it is still
under warranty, please see "How to Obtain Warranty Service" in
the Limited Warranty. Install a new CO Alarm immediately.
• The Test/Silence button is the only proper way to test the CO
Alarm. NEVER use vehicle exhaust! Exhaust may cause perma-
nent damage and voids your warranty.
*
For a list of acceptable replacement batteries, see “Regular Maintenance.”
R
EGULAR MAINTENANCE
To keep the CO Alarm in good working order:
•
Test it every week using the Test/Silence button.
• Vacuum the CO Alarm cover once a month, using the soft brush
attachment. Never use water, cleaners, or solvents, since these
may damage the unit. Test the CO Alarm again after vacuuming.
•
Replace the battery when the CO Alarm “chirps” about every
m
inute (the low battery warning).
The low battery warning should last for 7 days, but you should replace
the battery immediately to continue your protection.
C
hoosing a replacement battery:
T
his CO Alarm requires one standard 9 volt battery. The following
b
atteries are acceptable as replacements: Duracell MN1604, Energizer
5
22, and Ultralife U9VL-J-P. These replacement batteries are commonly
a
vailable at local retail stores.
•
Always use the exact batteries specified by this User’s Manual.
D
O NOT use rechargeable batteries. Clean the battery contacts
a
nd also those of the device prior to battery installation. Install
b
atteries correctly with regard to polarity (+ and -).
•
Please dispose of or recycle used batteries properly, following
a
ny local regulations. Consult your local waste management
a
uthority or recycling organization to find an electronics
r
ecycling facility in your area. DO NOT DISPOSE OF BATTERIES
I
N FIRE. BATTERIES MAY EXPLODE OR LEAK.
•
Keep battery out of reach of children. In the event a battery
i
s swallowed, immediately contact your poison control center,
y
our physician, or the National Battery Ingestion hotline at
2
02-625-3333 as serious injury may occur.
•
DO NOT spray cleaning chemicals or insect sprays directly on
o
r near the CO Alarm. DO NOT paint over the CO Alarm. Doing
s
o may cause permanent damage.
Household cleaners, aerosol chemicals, and other contaminants can
affect the sensor. When using any of these materials near the CO
Alarm, make sure the room is well ventilated.
T
his CO Alarm is intended for residential use. It is not intended for
u
se in industrial applications where Occupational Safety and Health
A
dministration (OSHA) requirements for carbon monoxide detectors
m
ust be met.
C
O alarms may not waken all individuals. If children or others do not
r
eadily waken to the sound of the CO alarm, or if there are infants or
f
amily members with mobility limitations, make sure that someone is
a
ssigned to assist them in the event of an emergency.
CO Alarms will not work without power. This alarm requires one
standard 9 volt battery to operate.
C
O Alarms for Solar or Wind Energy users and battery backup
p
ower systems: AC powered CO Alarms should only be operated with
t
rue or pure sine wave inverters. Operating this Alarm with most battery-
p
owered UPS (uninterruptible power supply) products or square wave or
“
quasi sine wave” inverters will damage the Alarm. If you are not sure
a
bout your inverter or UPS type, please consult with the manufacturer
t
o verify.
This CO Alarm will not sense carbon monoxide that does not reach
the sensor. This CO Alarm will only sense CO at the sensor. CO may be
present in other areas. Doors or other obstructions may affect the rate
at which CO reaches the CO Alarm. For this reason, if bedroom doors
are usually closed at night, we recommend you install a CO Alarm in
each bedroom and in the hallway between them.
C
O Alarms may not sense CO on another level of the home.
F
or example, a CO Alarm on the second level, near the bedrooms, may not
s
ense CO in the basement. For this reason, one CO Alarm may not give
a
dequate warning. Complete coverage is recommended. Place CO Alarms
o
n each level of the home.
C
O Alarms may not be heard. The alarm horn loudness meets or
e
xceeds current UL standards of 85 dB at 10 feet (3 meters). However,
i
f the CO Alarm is installed outside the bedroom, it may not wake up a
s
ound sleeper or one who has recently used drugs or has been drinking
a
lcoholic beverages. This is especially true if the door is closed or only
p
artly open. Even persons who are awake may not hear the alarm horn
i
f the sound is blocked by distance or closed doors. Noise from traffic,
s
tereo, radio, television, air conditioner, or other appliances may also
p
revent alert persons from hearing the alarm horn. This CO Alarm is not
i
ntended for people who are hearing impaired.
C
O Alarms are not a substitute for a smoke alarm. Although fire is a
s
ource of carbon monoxide, this CO Alarm does not sense smoke or fire.
T
his CO Alarm senses CO that may be escaping unnoticed from mal-
f
unctioning furnaces, appliances, or other sources. Early warning of fire
r
equires the installation of smoke alarms.
C
O Alarms are not a substitute for life insurance. Though these CO
A
larms warn against increasing CO levels, BRK Brands, Inc. does not
w
arrant or imply in any way that they will protect lives from CO poisoning.
H
omeowners and renters must still insure their lives.
CO Alarms have a limited life. Although the 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 your CO Alarm weekly.
CO Alarms are not foolproof. Like all other electronic devices, CO
Alarms have limitations. They can only detect CO that reaches their
sensors. They may not give early warning to rising CO levels if the CO
is coming from a remote part of the home, away from the CO Alarm.
TROUBLESHOOTING GUIDE
CO Alarm sounds frequently even though no
high levels of CO are revealed in an investigation.
The CO Alarm may be improperly located. Refer
to “Where to Install CO Alarms.”
Relocate your alarm. If frequent alarms continue,
have home rechecked for potential CO problems.
You may be experiencing an intermittent CO
problem.
The light flashes (RED) and the horn sounds
5 “chirps” every minute.
END OF LIFE SIGNAL. CO Alarm needs to be
replaced.
Immediately replace the CO Alarm.
If you have any questions that cannot be answered by reading this manual, call Consumer Affairs at 1-800-323-9005.

TO MOUNT ON THE WALL
T
ools you will need: pencil, drill with 3/16” or 5mm drill bit,
f
lathead screwdriver, hammer.
1
. Choose a location on the wall. Do not install the Alarm closer than
4
” (102 mm) from where the wall meets the ceiling.
2. Hold the mounting guide template against the wall, and make a
mark inside each keyhole where you will drill your mounting hole as
shown in the diagram below.
3. Use a 3/16” (5 mm) drill bit to drill through the marks you made for
the mounting holes.
4
. Insert the plastic screw anchors into the mounting holes until they
a
re flush with the wall. If necessary, tap them gently with a hammer.
5. Insert the screws into the anchors until the screwhead is 1/8 inch
(3 mm) away from the wall.
6. Slide the CO Alarm onto the screws until you feel it click into place.
7
. Test the CO Alarm as described in “Weekly Testing.”
“
ALARM-MOVE TO FRESH AIR”
I
f you hear the alarm horn and the Red light is flashing,
m
ove everyone to a source of fresh air.
D
O NOT disconnect the batteries from the CO Alarm!
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.
I
mproper use of appliance/device: operating a barbecue grill or
v
ehicle 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.
*For a list of acceptable replacement batteries, see “Page 4: Regular Maintenance.”
GENERAL LIMITATIONS OF CO ALARMS
T
he following conditions can result in transient CO situations:
1
. Excessive spillage or reverse venting of fuel appliances caused by
o
utdoor 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
f
resh air.
•
Vent pipe connections vibrating loose from clothes dryers,
f
urnaces, 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
g
round.
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.
