All First Alert®and BRK®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 photoelectric 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.

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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.
• This Alarm has a sealed lithium 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 stare directly into light source. Direct exposure to light may harm eyesight.
• Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
HOW TO INSTALL THIS ALARM

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,
7010B, 7010BSL, 7020B, SC7020B, SC7010BV, SA520; BRK CO Alarm Models CO5120BN,
CO5120PDBN, BRK Heat Alarm Models HD6135, HD6135FB, BRK Auxiliary Device
Models RM4, SL177. See www.brkelectronics.com for most current interconnect list.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms).
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
This type of wire is commonly available at Hardware and Electrical Supply stores. The
interconnect wire should be #18 gauge or larger, rated at least 300V. If an interconnect
wire is not already part of your household wiring, you will need to install one.
• All wiring must conform to all local electrical codes and Canadian Electrical Code,
CSA 22.1, and/or your local building code for further connection requirements.

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 Alarm at least once a month; gently vacuum the outside of the Alarm
using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.
PERMANENTLY DISABLING THE ALARM

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.

California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Changes or modifications to the product, not expressly approved by First Alert /
BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.

All First Alert®and BRK®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 photoelectric 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.

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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.
• This Alarm has a sealed lithium 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 stare directly into light source. Direct exposure to light may harm eyesight.
• Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
HOW TO INSTALL THIS ALARM
This Alarm 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 (if allowed by local codes). Read “Recommended Locations For
Smoke Alarms” and “Locations to Avoid For Smoke Alarms” before you begin installation.
Tools you will need: Standard Flathead Screwdriver, Wire Strippers

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,

using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

will flash. The Red LEDs will remain OFF on any remaining alarms in the series.
This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.
PERMANENTLY DISABLING THE ALARM
After 10 years of operation or low battery warning, permanently disable the alarm by following

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.
AGENCY PLACEMENT RECOMMENDATIONS

72®are registered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02269).
California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Changes or modifications to the product, not expressly approved by First Alert /
BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.

All First Alert®and BRK®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 photoelectric 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.

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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.
• This Alarm has a sealed lithium 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 stare directly into light source. Direct exposure to light may harm eyesight.
• Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
HOW TO INSTALL THIS ALARM

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,
7010B, 7010BSL, 7020B, SC7020B, SC7010BV, SA520; BRK CO Alarm Models CO5120BN,
CO5120PDBN, BRK Heat Alarm Models HD6135, HD6135FB, BRK Auxiliary Device
Models RM4, SL177. See www.brkelectronics.com for most current interconnect list.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms).
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
This type of wire is commonly available at Hardware and Electrical Supply stores. The
interconnect wire should be #18 gauge or larger, rated at least 300V. If an interconnect
wire is not already part of your household wiring, you will need to install one.
• All wiring must conform to all local electrical codes and Canadian Electrical Code,
CSA 22.1, and/or your local building code for further connection requirements.
Chapter 2 and/or your local building code for further connection requirements.

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 Alarm at least once a month; gently vacuum the outside of the Alarm
using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.
PERMANENTLY DISABLING THE ALARM

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.

California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Changes or modifications to the product, not expressly approved by First Alert /
BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.

All First Alert®and BRK®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 photoelectric 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.

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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.
• This Alarm has a sealed lithium 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 stare directly into light source. Direct exposure to light may harm eyesight.
• Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
HOW TO INSTALL THIS ALARM
This Alarm 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 (if allowed by local codes). Read “Recommended Locations For
Smoke Alarms” and “Locations to Avoid For Smoke Alarms” before you begin installation.
Tools you will need: Standard Flathead Screwdriver, Wire Strippers
Make sure the Alarm is not receiving excessively noisy power. Examples of noisy

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,
7010B, 7010BSL, 7020B, SC7020B, SC7010BV, SA520; BRK CO Alarm Models CO5120BN,
CO5120PDBN, BRK Heat Alarm Models HD6135, HD6135FB, BRK Auxiliary Device
Models RM4, SL177. See www.brkelectronics.com for most current interconnect list.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms).
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
This type of wire is commonly available at Hardware and Electrical Supply stores. The
interconnect wire should be #18 gauge or larger, rated at least 300V. If an interconnect
wire is not already part of your household wiring, you will need to install one.
• All wiring must conform to all local electrical codes and Canadian Electrical Code,
CSA 22.1, and/or your local building code for further connection requirements.

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 Alarm at least once a month; gently vacuum the outside of the Alarm
using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.
PERMANENTLY DISABLING THE ALARM
After 10 years of operation or low battery warning, permanently disable the alarm by following
the diagram below. Insert tool into slot in red disable switch. Slide switch fully to the left.

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.
AGENCY PLACEMENT RECOMMENDATIONS

72®are registered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02269).
California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Changes or modifications to the product, not expressly approved by First Alert /
BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.

All First Alert®and BRK®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 photoelectric 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.
INTRODUCTION
Thank you for choosing First Alert®for your Smoke Alarm and hearing impaired strobe

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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 basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,
7010B, 7010BSL, 7020B, SC7020B, SC7010BV, SA520; BRK CO Alarm Models CO5120BN,
CO5120PDBN, BRK Heat Alarm Models HD6135, HD6135FB, BRK Auxiliary Device
Models RM4, SL177. See www.brkelectronics.com for most current interconnect list.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms).
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
This type of wire is commonly available at Hardware and Electrical Supply stores. The
interconnect wire should be #18 gauge or larger, rated at least 300V. If an interconnect
wire is not already part of your household wiring, you will need to install one.
• All wiring must conform to all local electrical codes and Canadian Electrical Code,
CSA 22.1, and/or your local building code for further connection requirements.
Chapter 2 and/or your local building code for further connection requirements.

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 Alarm at least once a month; gently vacuum the outside of the Alarm
using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.

California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Changes or modifications to the product, not expressly approved by First Alert /
BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.

All First Alert®and BRK®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 photoelectric 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.

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.
BEFORE YOU INSTALL THIS SMOKE
AND STROBE LIGHT COMBO ALARM
Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke
Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing
chamber, it alarms. It can give you more time to escape before fire spreads. This unit can
ONLY give an early warning of developing fires if it is installed, maintained and located
where smoke can reach it, and where all residents can hear/see it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
UNDERSTAND THE DIFFERENT TYPE OF SMOKE ALARMS
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
KNOW WHERE TO INSTALL YOUR SMOKE ALARMS
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in
every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended
Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
KNOW WHAT SMOKE ALARMS CAN AND CAN’T DO
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound
an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
CHECK YOUR LOCAL BUILDING CODES
This Smoke Alarm is designed to be used in a typical single-family home. It
alone will not meet requirements for boarding houses, apartment buildings,
hotels or motels. See “Special Compliance Considerations” for details.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke
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.
• 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, NFPA101; 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, 120VAC pure sine wave 60Hz
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.
• This Alarm must have AC or battery power to operate. If the AC power fails,
battery back-up will allow the alarm to sound for at least 4 minutes. If AC power
fails and the battery is weak, protection should last for at least 7 days. 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 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.
• Connect this unit ONLY to other compatible units. See “How To Install This 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.
• This Alarm has a sealed lithium 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 stare directly into light source. Direct exposure to light may harm eyesight.
• Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
HOW TO INSTALL THIS ALARM
This Alarm 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 (if allowed by local codes). Read “Recommended Locations For
Smoke Alarms” and “Locations to Avoid For Smoke Alarms” before you begin installation.
Tools you will need: Standard Flathead Screwdriver, Wire Strippers

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Alarm is similar whether you want to install one Alarm, or
interconnect more than one Alarm. If you are interconnecting more than one Alarm, you MUST
read “Special Requirements For Interconnected Alarms” below before you begin installation.
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.
1. Position the screw slots on the mounting bracket over the screws in the junction box.
Tighten screws into screw head recesses in mounting bracket. Do not over tighten.
2. Using wire nuts, connect the power connector to the household wiring.
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 UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on
the orange wire on the power connector.
• 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.
• 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 Alarms.
3. Plug the power connector into the back of the Alarm.
4. Position the base of the Alarm over the mounting bracket and turn. The Alarm can be
positioned over the bracket every 90°. Turn the Alarm clockwise (right) until the unit locks into
place. If this is the first time mounting the alarm, an activation chirp will be heard.
5. Check all connections.
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.
STAND-ALONE ALARM ONLY:
• If you are only installing one Alarm, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
• If you are interconnecting multiple Alarms, repeat steps 1-5 for each Alarm in
the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete
may result in serious electrical shock, injury or death.
6. Make sure the Alarm is receiving AC power. Under normal operation,
the Green power indicator light will shine continuously.
7. If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION
BOX and recheck all connections. If all connections are correct and the Green power indicator
still does not light when you restore the power, the unit should be replaced immediately.
8. Test each Alarm. Press and hold the Test/Silence button until the unit alarms.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections.
If it does not alarm when you restore power, replace it immediately.
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 Alarms can be interconnected. Under AC power, all units will alarm
when one senses smoke. When power is interrupted, only the AC/DC units in the series
will continue to send and receive signals. AC powered Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially
if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke,
all units will alarm. To determine which Alarm initiated an alarm, see below:
• On Initiating Alarms Red LED flashes rapidly
• On All Other Alarms Red LED is Off
Interconnect units within a single family residence only. Otherwise all households will
experience unwanted alarms when you test any unit in the series. Interconnected units will
only work if they are wired to compatible units and all requirements are met. This unit is
designed to be compatible with: First Alert®/ BRK®Models 9120, 9120B, SC9120B, 7010,
7010B, 7010BSL, 7020B, SC7020B, SC7010BV, SA520; BRK CO Alarm Models CO5120BN,
CO5120PDBN, BRK Heat Alarm Models HD6135, HD6135FB, BRK Auxiliary Device
Models RM4, SL177. See www.brkelectronics.com for most current interconnect list.
Interconnected units must meet ALL of the following requirements:
• A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms).
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
This type of wire is commonly available at Hardware and Electrical Supply stores. The
interconnect wire should be #18 gauge or larger, rated at least 300V. If an interconnect
wire is not already part of your household wiring, you will need to install one.
• All wiring must conform to all local electrical codes and Canadian Electrical Code,
CSA 22.1, and/or your local building code for further connection requirements.

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 Alarm at least once a month; gently vacuum the outside of the Alarm
using your household vacuum’s soft brush attachment. Test the Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the 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
“Locations To Avoid For Smoke Alarms” for details.
• When the battery back-up becomes weak, the Alarm will “chirp” about once
a minute (the low battery warning). This warning should last 7 days, but you
should replace the unit immediately to continue your protection.
If the strobe light lens is loose or broken, the entire unit should be replaced
immediately. Never remove the strobe light lens for any reason. Doing so
can permanently damage the unit and will void your warranty.
Actual battery service life depends on the alarm and the environment in which it is installed.
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 UL STD 217.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
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 Alarm. Press and hold the Test/Silence
button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a
few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately. During testing, you
will hear a loud, 3 beeps, pause, 3 beeps and the strobe light will begin flashing.
When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm, when
you test that alarm you will hear a loud repeating horn pattern from this alarm: 4 rapid
beeps, pause, 4 rapid beeps, pause. In addition, the strobe light will flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK combination smoke & carbon monoxide alarm,
when you test that alarm you will hear a loud continuous beeping sound and the strobe light
will flash constant approximately 1 flash per second. Then you will hear a loud repeating horn
pattern from this alarm: 4 rapid beeps, pause, 4 rapid beeps, pause and the strobe light will flash
approximately 1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
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.Do not look directly at or touch the lens while the strobe
light is flashing. Doing so can hurt your eyes or burn your fingers.
PROPER DISPOSAL OF UNIT
To Properly Dispose of Unit: Waste electrical products should not be disposed
of with regular household waste. Please recycle where facilities exist. Check local
requirements for disposal of Lithium powered electronic devices. Alarm should be
disabled before disposal. See “Permanently Disabling the Alarm” section.
IF THIS SMOKE & STROBE LIGHT ALARM SOUNDS
RESPONDING TO AN ALARM
During a smoke incident at this alarm, you will hear 3 beeps, pause, 3 beeps and
the strobe light will flash constant approximately 1 flash per second.
Note: If you have interconnected this alarm with a BRK carbon monoxide alarm or
combination smoke & carbon monoxide alarm, if there is a carbon monoxide incident
you will hear a loud repeating horn pattern from this alarm: 4 rapid beeps, pause, 4
rapid beeps, pause. In addition, the strobe light will intermittently flash approximately
1 flash per second for four flashes, then 3 seconds off. The pattern is repeated.
If you have interconnected this alarm with a BRK smoke alarm, heat alarm
or a combination smoke & carbon monoxide alarm, if there is a smoke
incident you will hear a loud continuous beeping sound, pause and the
strobe light will flash consistently (approximately 1 flash per second).
• 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 “Limitations of Smoke Alarms” for
details. Battery Backup: Battery provides backup for the smoke alarm
during power outages. (Note: will not power the strobe light).

This feature helps responders identify which unit(s) triggered the alarm.
**NOTE: The strobe light will not operate under battery power.
***NOTE: Latching feature will not operate under battery power.
USING THE SILENCE FEATURES
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 extinguish a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence
this Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the silence mode.
WHEN THE SMOKE ALARM IS SILENCED...
The Smoke Alarm will remain silent for up to 10 minutes, then return to normal operation.
If the smoke has not cleared–or continues to increase–the device will go back into alarm.
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.
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. However, replace
the unit 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).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. This feature will only
work with AC power. After smoke levels drop below alarm levels, the Red LED will begin to flash
once every few seconds. It will continue to flash or “latch” until you clear it by testing the alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of smoke.
This can help investigators pinpoint the source of smoke.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you
to an alarm that occurred while you were away from home, even though
smoke present in the air has dropped below alarm levels.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When
this occurs, the LED flashes Green On for 2 seconds/Off for 2 seconds. This feature is
designed to help you identify which Alarm needs to be 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.
“SMART INTERCONNECT” FEATURE
This Alarm includes “Smart Interconnect” which enables the Alarm to be interconnected
with other First Alert®and 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.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead or weak batteries, a build-up of dirt, dust
or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm
as described in “Regular Maintenance,” then test the Smoke Alarm again. If it fails to test properly
when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
• If you hear a “chirp” approximately once a minute, replace the unit.
• If you experience frequent non-emergency alarms (like those
caused by cooking smoke), try relocating the Alarm.
• If the alarm sounds when no smoke is visible, try cleaning
or relocating the Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is
receiving AC power from the household current.
Always disable the branch circuit before servicing an AC or AC/DC Alarm. First, turn off the
AC power at the circuit breaker or fuse box. Next, remove the battery from Alarms with battery
back-up. Finally, press and hold the test button for 5-10 seconds to disable the branch circuit.
Do not try fixing the alarm yourself – this will void your warranty!
If the Alarm is still not operating properly, and it is still under warranty, please
see “How to Obtain Warranty Service” in the Limited Warranty.
PERMANENTLY DISABLING THE ALARM

RECOMMENDED PLACEMENT
FOR HEARING IMPAIRED SMOKE ALARMS
WITH INTEGRATED STROBE LIGHT
Smoke Alarms with Integrated Strobe lights intended for the hearing impaired should be located in
the bedroom where a hearing impaired person sleeps. Additional alarms should be located in any
room where a hearing impaired person may be present and need to be notified of a smoke danger.
According to NFPA 72, for wall mounting, a 177 candela strobe light must be used
in a sleeping area when mounting height of lens is less than 24 inches (61 cm)
from the ceiling. A Smoke Alarm with an integrated Strobe light must be placed
in accordance with the Smoke Alarm placement recommendations.
For Wall Mounting the alarm should be between 4 inches and 12 inches (100 mm and 300
mm) from ceiling to avoid the “dead air space”. For Ceiling Mounting the alarm should
be placed at least 4 inches (100 mm) from wall or corner (see “Locations to Avoid for
Smoke Alarms” below). In addition, for wall or ceiling mounting, the unit must be located
within 16 linear feet (4.8 meters) from top of lens to the pillow (see diagram below).
RECOMMENDED PLACEMENT
STROBE LIGHT OUTPUT FOR WALL & CEILING MOUNTING
The intensity of the strobe light gradually lessens as the angle increases. In other
words, the light is brightest directly in front of the strobe light and is progressively less
bright to either side. The following illustrations show how the strobe light is dispersed.
Use them to help you choose where to locate units for the hearing impaired.
PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES
Individuals who are susceptible to photosensitive epilepsy might have an increased
probability for seizures with multiple strobe lights flashing asynchronously. The frequency
or speed of flashing light that is most likely to cause seizures varies from person to person.
Generally, flashing lights most likely to trigger seizures are between the frequency of 5
to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.
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° C) and 100° F
(38° 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.
AGENCY PLACEMENT RECOMMENDATIONS

72®are registered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02269).
California State Fire Marshal (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A Smoke Alarm installed in each
separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms
in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace
rooms, closets, utility and storage rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these 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 distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended the Smoke 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 Alarm is
placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep
units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40° F (4° C) or above 100° F (38° C) including
unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the
stove or range. Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke
away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is
not possible, install the Smoke Alarm at least 4 inches (100 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (100 mm) and 12 inches (300
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet
(0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms
may be required depending on the length, angle, etc. of the ceiling’s slope.
ABOUT SMOKE ALARMS IN GENERAL
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. They do not, however, provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected functionality as with hardwired
alarms, without wires. Units are easy to install and do not require professional installation. They
provide protection even when electricity fails, provided the batteries are fresh and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered Smoke Alarms should only be operated with true or pure sine wave inverters.
Operating this Smoke 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. These
units 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 local building codes as they may
also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
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, long-term health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if they were once single-family homes. 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.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.

BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
GENERAL LIMITATIONS OF SMOKE ALARMS
Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide.
However, like any warning device, Smoke Alarms can only work if they are properly located,
installed, and maintained, and if smoke reaches the Alarms. They are not foolproof.
Smoke 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 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 alarm while
sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke 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.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in
chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber
and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—
especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another floor or area of the dwelling. For example,
a stand-alone unit on the second floor may not detect smoke from a basement fire until the fire
spreads. This may not give you enough time to escape safely. That is why recommended minimum
protection is at least one unit in every sleeping area, and every bedroom on every level of your
dwelling. Even with a unit on every floor, stand-alone units may not provide as much protection as
interconnected units, especially if the fire starts in a remote area. Some safety experts recommend
installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or
professional fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units
may provide earlier warning than stand-alone units since all units alarm when one detects smoke.
Smoke Alarms may not be heard. Though the alarm horn in this unit meets or exceeds
current standards, it may not be heard if: 1) the unit is located outside a closed or
partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is
drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4)
residents are hearing impaired or sound sleepers. Special purpose units, like those with
visual and audible alarms, should be installed for hearing impaired residents.
Smoke Alarms 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.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are
made of components that can wear out or fail at any time. You must test the unit
weekly to ensure your continued protection. Smoke Alarms cannot prevent or
extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not
operating properly. You should always replace a Smoke Alarm after 10 years from date
of purchase. Write the purchase date on the space provided on back of unit.
