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 elec-
trical 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
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.
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
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; Article 760 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 elec-
trician. 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.

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 rec-
For CO Alarms, the National Fire Protection Association (NFPA) recom-
mends that a CO Alarm should be centrally located outside of each sep-
arate 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
• On every level of your home, including finished attics and base-
• 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 stor-
age areas, where temperatures normally remain between 40˚ F and
100˚ F (4˚ C and 38˚ C).
• 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 informa-
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˚ C) or hotter than
100˚ F (38˚C). These areas include non-airconditioned crawl spaces,
unfinished attics, uninsulated or poorly insulated ceilings, porches,
• In insect infested areas. Insects can clog the openings to the sens-
• 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
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 hor-
izontally. 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.
SUGGESTED AREAS FOR INSTALLING
SMOKE ALARMS, CO ALARMS, AND COMBO UNITS

BEFORE YOU BEGIN INSTALLATION
This unit is designed to be mounted on any standard wiring junction
box up to a 4-inch (10 cm) size, on either the ceiling or wall. Read
“Where to Install This Alarm” and “Where This Alarm Should Not Be
Installed ” before you begin installation. If a junction box is not already
in place, install one using standard #12 or #14 gauge copper wire.
• Make sure the alarm is not receiving excessively noisy power.
Examples of noisy power could be major appliances on the
same circuit, power from a generator or solar power, light dim-
mer on the same circuit or mounted near fluorescent lighting.
Excessively noisy power may cause damage to your Alarm.
Find the pair of self-adhesive labels included with this Smoke/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 Smoke/CO Alarm, and the other label in
the “fresh air” location you plan to go if the alarm sounds.
NOTE: A qualified appliance technician is defined as “a person, firm,
corporation, or company that either in person or through a representa-
tive, is engaged in and responsible for the installation, testing, servicing,
or replacement of heating, ventilation, air conditioning (HVAC) equipment,
combustion appliances and equipment, and/or gas fireplaces or other

• 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
Interconnected units can provide earlier warning of a Smoke/CO prob-
lem 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

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 equip-
ment and appliances, and inspect for proper operation of this equip-
ment. 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 informa-
tion 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
• 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 rapid-
ly. 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 SILENCE FEATURE
EVER disconnect the power to your Smoke/CO Alarm to silence the
horn—use the Silence Feature. Disconnecting the Smoke/CO Alarm
removes your protection! If the unit will not silence or if it stays in
silence mode continuously, it should be replaced immediately.
• 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.
• To use the Silence Feature, press the Test/Silence button until you
hear the acknowledge “chirp” or until the horn is silent.
• If the Test/Silence button is pressed while the Smoke/CO Alarm is
in the silence mode, the alarm will start sounding again.
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.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 15 minutes and then return
to normal operation. If the smoke has not cleared within the silence peri-
od or if smoke increases to a critical level during the silence period, the
unit will go back into alarm.
Use the Silence Feature only if you are certain of the source of
smoke. If you are not certain of the source or a fire starts while
you are clearing smoke, evacuate the house immediately. Not
responding to an alarm can result in property loss, injury, or death.
WHEN THE CO ALARM IS SILENCED...
The CO Alarm will remain silent for 4 minutes. While the Alarm is
silenced, it will continue to monitor the air for CO. After 4 minutes, if CO
levels remain potentially dangerous the horn will start sounding again.
The Silence Feature is intended to temporarily silence the Alarm horn. It
will not correct a CO problem.
LOW BATTERY SILENCE FEATURE
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
