FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters away
from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload electrical
circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys grease-
and debris-free; 6) Never leave anything cooking on the stove unattended;
7) Keep portable heaters and open flames, like candles, away from
flammable materials; 8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot alert
you to a fire. Keep at least one working fire extinguisher on every floor, and an
additional one in the kitchen. Have fire escape ladders or other reliable means
of escape from an upper floor in case stairs are blocked.
BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences. It is NOT designed for marine or RV use.
•
This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
All BRK
®
and
First Alert
®
Smoke Alarms conform to regulatory
requirements, including UL217 and are designed to detect particles
of combustion. Smoke particles of varying number and size are
produced in all fires.
Ionization technology is generally more sensitive than photo-
electric technology at detecting small particles, which tend to be
produced in greater amounts by flaming fires, which consume
combustible materials rapidly and spread quickly. Sources of these
fires may include paper burning in a wastebasket, or a grease fire in
the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area
where the Smoke/CO Alarm is installed before removing it from
the mounting bracket. Failure to turn off the power first may
result in serious electrical shock, injury or death.
• This unit will not alert hearing impaired residents. It is
recommended that you install special units which use devices
like flashing strobe lights to alert hearing impaired residents.
• Installation of this unit must conform to the electrical codes
in your area; Articles 210 and 300.3 (B) of NFPA 70 (NEC),
NFPA 72, NFPA 101; ICC; SBC (SBCCI); UBC (ICBO);
NBC (BOCA); OTFDC (CABO), and any other local or building
codes that may apply. Wiring and installation must be
performed by a licensed electrician. Failure to follow these
guidelines may result in injury or property damage.
• This unit must be powered by a 24-hour, 120V AC pure sine
wave 60 Hz circuit. Be sure the circuit cannot be turned off
by a switch, dimmer, or ground fault circuit interrupter.
Failure to connect this unit to a 24-hour circuit may prevent it
from providing constant protection.
Unit may be connected to
an arc fault circuit interrupter.
•
This Smoke/CO Alarm must have AC or battery power to
operate. If AC power fails and the battery is dead or missing,
the alarm cannot operate.
• Never disconnect the power from an AC powered unit to
stop an unwanted alarm. Doing so will disable the unit and
remove your protection. In the case of a true unwanted
alarm, use the Silence Feature (if equipped), open a window
or fan the smoke away from the unit. The alarm will reset
automatically when it returns to normal operation. Never
remove the batteries from a battery operated unit to stop an
unwanted alarm (caused by cooking smoke, etc.). Instead
open a window or fan the smoke away from the unit. The
alarm will reset automatically.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
In general, install combination Smoke and Carbon Monoxide
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
(12 meters) long, install a unit at each end.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and storage
areas, where temperatures normally remain between 40˚ F and
100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the
center as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.
Installing Smoke/CO Alarms in Mobile Homes
For minimum security install one Smoke/CO Alarm as close to each
sleeping area as possible. For more security, put one unit in each room.
Many older mobile homes (especially those built before 1978) have little
or no insulation. If your mobile home is not well insulated, or if you are
unsure of the amount of insulation, it is important to install units on
inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, kitchens, furnace rooms, crawl spaces and unfinished
attics. Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke/CO Alarm
be placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke/CO
Alarm is placed directly next to a fuel-burning source. Ventilate
these areas as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the
sensing chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line.
On a peaked, gabled, or cathedral ceiling, install the first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.

ELECTRICAL SHOCK HAZARD. Turn off power to the area where you
will install this unit at the circuit breaker or fuse box before beginning
installation. Failure to turn off the power before installation may
result in serious electrical shock, injury or death.
To install this unit:
1. Remove the mounting bracket from the base. Position the screw
slots on the mounting bracket over the screws in the junction box.
Tighten the screws.
Improper wiring of the power connector or the wiring leading to
the power connector will cause damage to the Alarm and may lead
to a non-functioning Alarm.
2. Using wire nuts, connect the power connector to the AC power.
3. Plug the power connector into the back of the Smoke/CO Alarm.
4.
Position the base of the Smoke/CO Alarm over the mounting bracket
and turn. The Alarm will remain secure over a wide rotation range to
allow for perfect alignment. When wall mounting, this will allow fine-
tuning on the positioning to compensate for out of aligned wall studs
and to keep the wording level. The Alarm can be positioned over the
bracket every 120°. Rotate the Alarm until aligned properly.
STAND ALONE ALARM ONLY:
• Connect the white wire on the power connector to the neutral
wire in the junction box.
• Connect the black wire on the power connector to the hot wire
in the junction box.
• Tuck the orange wire inside the junction box. It is used for
interconnect only.
INTERCONNECTED ALARMS ONLY:
Strip off about 1/2” of the plastic coating on the orange
interconnect wire on the power connector.
• Connect the white wire on the power connector to the neutral
wire (usually white) in the junction box.
• Connect the black wire on the power connector to the hot wire
(usually black) in the junction box.
• Connect the orange wire on the power connector to the
interconnect wire in the junction box. Repeat for each unit you
are interconnecting. Never connect the hot or neutral wires in
the junction box to the orange interconnect wire. Never cross
hot and neutral wires between interconnected Alarms.
SPECIAL REQUIREMENTS FOR INTERCONNECTED ALARMS
•
Failure to meet any of the above requirements could damage
the units and cause them to malfunction, removing your
protection.
• AC and AC/DC Smoke/CO Alarms can be interconnected.
Under AC power, all units will alarm when one senses smoke
or CO. When power is interrupted, only the AC/DC units in
the series will continue to send and receive signals.
AC powered Smoke/CO Alarms will not operate. See “Smart
Interconnect” Feature.
Interconnected units can provide earlier warning of a Smoke/CO problem
than stand-alone units, especially if the problem starts in a remote area of
the dwelling. If any unit in the series senses Smoke/CO, all units will alarm.
To determine which Smoke/CO Alarm initiated an alarm, refer to the table.
During an Alarm:
On Initiating Alarm(s) – Red LED(s) flashes (flash) rapidly
On All Other Alarms – Red LED is Off
After an Alarm (Latching):
On Initiating Alarm(s) – Red LED(s) On for 2 seconds/Off for 2 seconds
On All Other Alarms – Green LED(s) On, Red LED(s) is Off
Compatible Interconnected Units

HOW YOUR SMOKE/CO ALARM WORKS
THE COVER OF YOUR SMOKE/CO ALARM
The locking features are designed to discourage unauthorized removal of
the battery or alarm. It is not necessary to activate the locks in single-family
households where unauthorized battery or alarm removal is not a concern.
This alarm has two separate locking features: one to lock the battery compartment,
and the other to lock the Smoke Alarm to the mounting bracket. This alarm is shipped
from the factory with the battery drawer locked because it features a 10 year battery
backup. Under normal conditions you should not have to replace the battery for the
life of the alarm. If you need to replace the battery follow the UNLOCK THE BATTERY
COMPARTMENT instructions below. Re-lock Battery Compartment if desired.
Tools you will need: • Needle-nose pliers or utility knife
• Standard/Flathead screwdriver.

IF THE CO ALARM 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
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your Smoke/CO Alarm remains
in its normal condition.
4. After following steps 1-3, if your Smoke/CO Alarm reactivates within
a 24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of
this equipment. If problems are identified during this inspection
have the equipment serviced immediately. Note any combustion
equipment not inspected by the technician, and consult the
manufacturers’ instructions, or contact the manufacturers directly,
for more information about CO safety and this equipment. Make
sure that motor vehicles are not, and have not, been operating in
an attached garage or adjacent to the residence. Write down the
number of a qualified appliance technician here:
_____________________________________________________________
WHAT TO DO IF SMOKE IS DETECTED
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never disconnect the AC power to quiet an unwanted alarm.
Disconnecting the power disables the Alarm so it cannot
sense smoke. This will remove your protection. Instead, open
a window or fan the smoke away from the unit. The Alarm will
reset automatically.
• If the unit alarms get everyone out of the house immediately.
•
ELECTRICAL SHOCK HAZARD: Attempting to disconnect the
power connector from the unit when the power is on may result
in electrical shock, serious injury or death.
When an interconnected system of AC powered units is in alarm,
the alarm indicator light on the unit(s) that initiated the alarm will blink
rapidly. It will remain OFF on any remaining units.
If the unit alarms, get everyone out of the dwelling immediately.
If the unit alarms and you are certain that the source of smoke is not a
fire—cooking smoke or an extremely dusty furnace, for example—open
a nearby window or
door and fan the smoke away from the unit. Use
the Silence Feature to silence the Alarm. This will silence the alarm, and
once the smoke clears the unit will reset itself automatically.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home,
and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be
interconnected with other BRK Smoke, Heat, and “Smart Interconnect”
CO Alarms. When smoke is detected, all Alarms will sound the smoke
horn pattern. When CO is detected, “Smart Interconnect” Alarms
will sound the CO horn pattern. Alarms that do not have the “Smart
Interconnect” Feature will remain silent during a CO alarm.
Using the Optional Locking Features (Continued)
WHAT TO DO IF CARBON MONOXIDE IS DETECTED, Continued
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
• Connect this unit ONLY to other compatible units. See “How
To Install This Smoke/CO Alarm” for details. Do not connect
it to any other type of alarm or auxiliary device. Connecting
anything else to this unit may damage it or prevent it from
operating properly.
• The battery compartment resists closing unless a battery is
installed. This warns you the unit will not operate under DC
power without a battery.
• Do not stand too close to the unit when the alarm is sounding.
It is loud to wake you in an emergency. Exposure to the horn
at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the
sensing chambers and prevent the unit from operating properly.

do not operate with a missing battery and no AC Power.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature in
emergency situations. It will not correct a CO problem or extinguish a
fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover until you hear an acknowledge chirp.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
SILENCING THE LOW BATTERY WARNING
This Silence Feature can temporarily quiet the low battery warning
“chirp” for up to 8 hours if AC power is present. Press the Test/Silence
button on the Alarm cover until you hear the acknowledge “chirp”.
Once the low battery warning “chirp” silence feature is activated, the
unit continues to flash the green light once a minute for 8 hours. After
8 hours, the low battery “chirp” will resume. The Alarm will continue to
operate as long as AC power is supplied. Note, if battery is missing or
dead, Low Battery Silence cannot be activated and alarm with continue
to chirp approximately once per minute. However, replace the batteries
as soon as possible, to maintain protection in event of a power outage.
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).
To silence Alarms in an interconnected series:
To silence an interconnected series of Smoke/CO Alarms, you must
press the Test/Silence button on the initiating alarm (The unit with the
flashing red light; the red light will be off on all other Alarms.). If you
press the Test/Silence on any other Alarm, it will only silence that unit,
not the whole interconnected series.
