LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.

4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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.

condition has subsided. Low Battery Latch: Identifies which unit is in low battery condition.
Perfect Mount System. Includes a gasketless base for easy installation and a mounting bracket
that keeps the alarm secure over a wide rotation range to allow for perfect alignment.
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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.

LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, it is recommended you 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 (6-meter) 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 (4.4˚ C) or above 100˚ F (37.8˚ 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. Keep laundry room Smoke Alarms 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 the sensing chamber.
• In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
• Less than 12 inches (305mm) 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 (102 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 and 12 inches (102 and 305 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.
Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke,
all units alarm. They do not operate if electricity fails. AC with battery (DC) back-
up: will operate if electricity fails, provided the batteries are fresh and correctly
installed. AC and AC/DC units must be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-up: Interconnects with all
WIRELESS INTERCONNECT enabled Smoke and Smoke/CO Alarms without wires or connectors,
so when one alarm sounds, they all sound. Will operate if electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
Smoke 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.
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 them. If you are unsure which
type of Smoke Alarm to install, refer to Chapter 2 of the National Fire Protection Association (NFPA)
Standard 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National
Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building
codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day
care facilities, health care facilities, boarding houses, group homes and dormitories provided
a primary fire detection system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire detection systems
in places housing many people—like apartment buildings, condominiums, hotels, motels,
dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes
of any kind. It is not a suitable substitute for complete fire detection systems in warehouses,
industrial facilities, commercial buildings, and special-purpose non-residential buildings which
require special fire detection and alarm systems. Depending on the building codes in your
area, this Smoke Alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered Smoke
Alarms only. In existing construction, AC, AC/DC, or DC powered Smoke Alarms can be used
as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or consult your Fire Department
for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially those that fall under
HUD 223(f) MAP (Multi-family Accelerated Processing), may require a 10 Year sealed tamper
resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

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 them. 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 them. 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 home. 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 home. 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 ALARM
Important! 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 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.
• This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing
strobe lights to alert hearing impaired residents.
• Unit will not operate without battery power. The Smoke Alarm cannot work until
you install the batteries in the correct position (Match “+” to “+” and “-” to “-”).
• This Smoke Alarm has a battery drawer which resists
closing unless batteries are installed.
• Do not install this unit over an electrical junction box. Air currents around junction
boxes can prevent smoke from reaching the sensing chamber and prevent the unit
from alarming. Only AC powered units are intended for installation over junction boxes.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you
in an emergency. Exposure to the horn at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the sensing
chamber and prevent the unit from operating properly.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective way to provide
your family with whole-home safety. All WIRELESS INTERCONNECT Alarms communicate with
each other without wires or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you more time to react.
The communication distance (range) between any two WIRELESS INTERCONNECT Alarms is
typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number
of floors, number/size of rooms, furniture and types of building materials used may reduce
the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic
appliances (refrigerators) and metal studs. A feature of WIRELESS INTERCONNECT Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from structural conditions can
be overcome by adding additional Alarms to route the wireless signal around obstructions.
• The range and proper operation of any wireless device will vary depending
on its surroundings. It is very important that each Alarm is tested individually
before and after installation to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used outdoors or to transmit
between buildings. The Alarms will not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with signals from wireless
Alarms. Alarms should be tested after changes to your home such as
remodeling, moving furniture, and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke Alarm will automatically communicate
potential fires with all other First Alert®WIRELESS INTERCONNECT Smoke Alarms.
Changes or modifications not expressly approved by BRK Brands, Inc.
could void the user’s authority to operate the equipment.

OPTIONAL LOCKING FEATURES
The optional locking features are designed to prevent unauthorized removal of the battery or alarm. It is not necessary to
activate the locks in single-family households where unauthorized battery or alarm removal is not a concern.
These Smoke Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Smoke Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: Needle-nose pliers Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.

WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
• 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” for details.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range
may be harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly.
Using the test button is the recommended way to test this Smoke Alarm. Press and hold
the test 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 (LED will flash approximately once a minute indicating it has
power); and test it again. If it still does not alarm, replace it immediately. During testing
you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there
are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke Alarm at least once a month; gently vacuum off any dust using
your household vacuum’s soft brush attachment, and test the Smoke Alarm after
cleaning. Never use water, cleaners or solvents since they may damage the unit.
• If the Smoke 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 becomes weak, the Smoke Alarm unit will “chirp” approximately once
a minute (the low battery warning). This low battery warning should last for up to 7
days, but you should replace the battery immediately to continue your protection.
Choosing a replacement battery:
Your Smoke Alarm requires 2 “AA” batteries: Energizer E91 or Duracell MN1500.
These batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual. DO NOT use
rechargeable batteries. Clean the battery contacts and also those of the device prior
to battery installation. Install batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following any local
regulations. Consult your local waste management authority or recycling
organization to find an electronics recycling facility in your area. DO NOT
DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is swallowed,
immediately contact your poison control center, your physician, or the National
Battery Ingestion hotline at 202-625-3333 as serious injury may occur.
Actual service life depends on the Smoke Alarm and the environment in which it is installed.
All the batteries specified above are acceptable replacement batteries for this unit.
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap completely
into the battery compartment. Match the terminals on the
ends of the batteries with the terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
AB
IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause. The red LED will flash rapidly.
• 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 remove the batteries from a battery operated Smoke Alarm to stop an
unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables
the alarm so it cannot sense smoke, and removes 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.
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.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15 minutes. To use
this feature, press the “Push to Test/Silence” button on the cover. If the unit will not silence
and no heavy smoke is present, or if it stays in silence mode continuously, it should
be replaced immediately. The LED will continue to flash rapidly while in silence.
The Silence Feature does not disable the unit—it makes it temporarily less sensitive
to smoke. For your safety, if smoke around the unit is dense enough to suggest a
potentially dangerous situation, the unit will stay in alarm or may re-alarm quickly.
If you do not know the source of the smoke, do not assume it is an unwanted alarm.
Not responding to an alarm can result in property loss, injury, or death.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for up to 8 hours. You can
silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit continues to flash the
Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp” will resume. Replace
the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode
and the low battery warning will resume (LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After
smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash
On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about
15 minutes, to give you time to determine which unit initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery condition”. When this
occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes.
This feature is designed to help you identify which Alarm needs to have the battery replaced.
Although, the Alarm will sound the low battery chirp approximately once every minute, sometimes
during the initial stages of “low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low battery level. This innovative
feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing 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,” and install a
fresh battery, 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” about once a minute, replace the battery.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
• If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, try installing a new
battery, and make sure it is snapped in securely.
• If the alarm sounds 3 rapid “chirps” every minute; LED flashes approximately once a
minute. MALFUNCTION: the device is not working properly and needs to be replaced.
Do not try fixing the alarm yourself – this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in
every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC
powered and interconnected. See “Agency Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas,
finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F
(37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a
unit in each. If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second floor stairway, and at bottom of 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.
