Input: 120V AC, 60Hz, .060A Standby, .060A Alarm
Ionization smoke alarms are generally more effective at detecting 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 smoke alarms are generally more effective at detecting smoldering fires which
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 of your home.

SPECIAL COMPLIANCE CONSIDERATIONS
This smoke alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like
apartment buildings, condominiums, hotels, motels, dormitories, hospitals, long-term health care facilities, nursing homes,
day care facilities, or group homes of any kind—even if they wer e once single-family homes. It is not a suitable substitute for
complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose nonresidential buildings which require special fire detection and alarm systems. Depending on the building codes in your ar ea,
this smoke alarm may be used to provide additional protection in these facilities.
The following information applies to all four types of buildings listed below: In new construction, most building
codes require the use of AC or AC/DC power ed 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 Code) or NFPA 101
(Life Safety Code), local building codes, or consult your Fire Department for detailed fi re pr otection r equirements in buildings
not defined as “households.”
1. Single-Family Residence: Single family home, townhouse. It is recommended smoke alarms be installed on every level
of the home, in every bedroom, and in each bedroom hallway.
2. Multi-Family or Mixed Occupant Residence: Apartment building, condominium. This smoke alarm is suitable for use
in individual apartments or condos, 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 pr ovide
sufficient warning to all residents or meet local fire pr otection ordinances/regulations.
3. Institutions: Hospitals, day care facilities, long-term health care facilities. This smoke alarm is suitable for use in
individual patient sleeping/resident rooms, pr ovided 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 pr ovide
sufficient warning to all residents or meet local fire pr otection ordinances/regulations.
4. Hotels and Motels: Also boarding houses and dormitories. This smoke alarm is suitable for use inside individual
sleeping/resident rooms, provided a primary fi re detection system already exists to meet fire detection r equirements 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.
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 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 r each 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 fi r e spreads. This may not give you enough time to escape
safely. That is why r ecommended minimum pr otection 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 ar ea. Some safety experts recommend installing interconnected AC powered
units with battery back-up (see “Other Features Of 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 ar e made of components that can wear out or
fail at any time. You must test the unit weekly to ensure your continued pr otection. Smoke alarms cannot prevent or
extinguish fires. They are not a substitute for pr operty or life insurance.
Smoke alarms have a limited life. The unit should be replaced immediately if it is not operating pr operly. It is
recommended you replace a smoke alarm

WHERE TO INSTALL 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 ar ea, and
in every bedroom. In new construction, the smoke alarms must be AC powered and interconnected. See “Agency
Placement Recommendations” for details. For additional coverage, it is recommended that you install a smoke alarm in
all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚F (4˚C)
and 100˚F (38˚C). Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.

If a hall is more than 40 feet long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of the basement stairway .
IMPORTANT!
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. If you install AC or AC/DC units,
it is recommended they be interconnected for added protection.
INSTALLING SMOKE ALARMS IN MOBILE HOMES
For minimum security install one smoke alarm as close to each sleeping area as possible. For more security, put one unit
in each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile
home is not well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls
only. Smoke alarms should be installed where temperatures normally remain between 40˚F (4˚C) and 100˚F (38˚C).

codes may apply in your area. Always check compliance requirements before beginning any installation.
NFPA Standard 72 Section 2-2.1.1.1
2-2.1.1.1 Smoke alarms shall be installed outside of each separate sleeping ar ea in the immediate vicinity of the bedrooms
and on each additional story of the family living unit, including basements and excluding crawl spaces and unfi nished attics.
In new construction a smoke alarm shall also be installed in each sleeping room. Chapter 2 also reads as follows: 2-2.2.1: In
new construction, where more than one smoke alarm is r equired by 2-2.1, alarms shall be so arranged that operation of any
one alarm shall cause the operation of all alarms within the dwelling. A-2.5.2.1 Smoke Detection-Are More Smoke Alarms
Desirable? The required number of smoke alarms might not provide reliable early warning protection for those areas
separated by a door from the areas protected by the required smoke alarms. For this reason, it is r ecommended that the
householder consider the use of additional smoke alarms for those areas for increased protection. The additional areas
include the basement, bedrooms, dining room, furnace room, utility r oom, and hallways not pr otected by the r equired smoke
alarms. The installation of smoke alarms in kitchens, attics (finished or unfinished), or garages is not normally r ecommended,
as these locations occasionally experience conditions that can result in improper operation.
California State Fire Marshall
Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the
household as follows: A smoke alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and
heat or smoke alarms in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace rooms,
closets, utility and storage rooms, basements, and attached garages.

WHERE NOT TO INSTALL SMOKE ALARMS
For best performance, do not install the unit:
• 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. Ventilate these areas as much as possible.
• In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a
smoke alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least
10 feet (3 meters) away from showers, saunas, dishwashers, etc.
• Where the temperatures are regularly below 40˚ F (4˚C) or above 100˚ F (38˚ C) including unheated
buildings, outdoor rooms, porches, or unfinished attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a smoke alarm directly over the stove or range.
Clean a laundry room unit frequently to keep it free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit,
preventing it from reaching the sensing chamber.
• In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor .
• In “dead air” spaces (see “Avoiding Dead Air Spaces” below).

PROTECTING Y OUR FAMILY FROM FIRE
Putting up smoke alarms is one step in protecting your family fr om fir es. You must also reduce the chance a fire will start in
your home, and have a plan for escaping safely if one does. To have a good fire safety program, you must:
Develop a family escape plan and practice it with everyone in your family, including small children. 1) Draw a floor plan of
your home and identify at least two exits from each room and one way to get out of each bedroom without opening the door;
2) Decide on a meeting place a safe distance from home, and make sur e everyone knows to wait ther e; 3) Know wher e to go
to call the Fire Department from outside the home; 4) Make sure everyone—including all children—know what the alarm
signal means and how to react to it. Teach them they must be prepared to leave the home by themselves if needed; 5) Hold
fire drills every 6 months and practice how to escape safely. Show children how to check if doors are hot before opening
them. Show them how to use an alternate exit if a door is hot and shouldn’t be opened. Teach them to stay close to the floor
and crawl if necessary.
Install at least one smoke alarm on every level of your home, in every bedroom, and in every sleeping area.
Keep alarms clean, and test them weekly. Replace smoke 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.
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) Stor e 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.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan. Your safe escape may depend on thinking clearly and remembering what you have practiced.
• Get out of the house as quickly as possible. Don’t stop to get dr essed or collect anything.
• Feel doors with the back of your hand before opening them to see if they are hot. If a door is cool,
open it slowly. Don’t open a hot door—use an alternate escape route.
• Cover your nose and mouth with a cloth (preferably wet). Take short, shallow breaths.
• Keep doors and windows closed, unless you need to escape through them.
• 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 and on creating your own family escape plan.

IMPORTANT! READ BEFORE INST ALLING SMOKE ALARM
Read “Where To Install Smoke Alarms” and “Where Not To Install 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.
DANGER!
• ELECTRICAL SHOCK HAZARD. Turn off power to the ar ea where you will install this unit at the circuit
breaker or fuse box before beginning installation. Failure to turn off the power before installation may
result in serious electrical shock, injury or death.
WARNING!
• This unit will not alert hearing impaired residents. It is recommended that you install special units which
use devices like flashing strobe lights to alert hearing impaired residents.
• Installation of this unit must conform to the electrical codes in your area; Article 760 of the National
Electrical Code (NFPA 70), NFPA 72, 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA); OTFDC (CABO), and
any other local or building codes that may apply. Wiring and installation must be performed by a licensed
electrician. Failure to follow these guidelines may result in injury or property damage.
• This unit must be powered by a 24-hour, 120VAC 60Hz circuit. Be sure the circuit cannot be turned off by
a switch, dimmer, or ground fault circuit interrupter. Failure to connect this unit to a 24-hour circuit may
prevent it from providing constant protection.
• This alarm must have AC or battery power to operate. If the AC power fails, battery back-up will allow the
alarm to sound for at least 4 minutes (if the battery is weak, protection should last for up to 7 days.) If AC
power fails and the battery is dead or missing, the alarm cannot operate.
• It is possible an electrical fire could occur on the circuit powering this unit. If this happened, the power to
the unit could be cut off and it may fail to alarm. Some safety experts recommend wiring warning devices
like this unit on separate circuits from other appliances, since these circuits are not as likely to be overloaded. Other safety experts recommend wiring these units on the same circuits as appliances so it is
more readily apparent if the circuit fails. Whichever circuit you choose, it is recommended you also install
battery powered units as back-ups in case of fire on the circuit powering the AC powered units.
• Never disconnect the power from an AC powered unit to stop an unwanted alarm. Doing so will disable
the unit and remove your protection. In the case of a true unwanted alarm open a window or fan the
smoke away from the unit. The alarm will reset automatically when it returns to normal operation. Never
remove the batteries from a battery operated unit to stop an unwanted alarm (caused by cooking smoke,
etc.). Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
CAUTION!
• Connect this unit ONLY to other compatible units. See “How To Install This Smoke Alarm” for details. Do
not connect it to any other type of alarm or auxiliary device. Connecting anything else to this unit may
damage it or prevent it from operating properly.
• 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. When testing the unit, step back when the
horn starts sounding.
• Do not paint over the unit. Paint may clog the openings to the sensing chamber and prevent the unit from
operating properly.
• The battery was shipped “backwards” to keep it fresh. The unit cannot receive battery back-up power
until you remove the battery and reposition it properly.
• This unit has a “missing battery” tab that prevents it from attaching to the mounting bracket unless a
battery is installed. This warns you the battery back-up will not operate without a battery.
HOW TO INSTALL THIS SMOKE ALARM
This unit is designed to be mounted on any standard wiring junction box up to a 4- inch diagonal size, on either the ceiling
or wall (if allowed by local electrical codes). Read “Where to Install Smoke Alarms” and “Where Not To Install Smoke
Alarms” before you begin installation.
Important Installation Parts
The Mounting Bracket

alarms, repeat steps 1-7 for each smoke alarm
in the series. When you are finished, restore
power to the junction box.
In an interconnected series, you must test each smoke alarm individually.
During testing, you will hear a loud, repeating horn pattern:
Special Requirements For Interconnected Smoke Alarms
WARNING!
• Failure to meet any of the requirements for interconnecting smoke alarms could damage the units, and
cause them to malfunction, removing your protection.
• AC and AC/DC smoke alarms can be interconnected. Under AC power, all units will alarm when one senses
smoke. When power is interrupted, only the AC/DC units in the series will continue to send and receive
signals. AC powered smoke alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially if a fire starts in a remote area of the
home. If any unit in the series senses smoke, all units will alarm. This unit can be interconnected with
SA4120B, SA4121B, SA4919B, SA86B, SA100B
5919, 5919TH, 86RAC;
IMPORTANT!
Interconnect units within a single family residence only . Otherwise all households will experience unwanted alarms when you test
any unit in the series. Interconnected units will only work if they are wired to compatible units and all requirements are met.
Interconnected units must meet ALL of the following requirements:
•A maximum of 18 units total may be interconnected (Maximum of 12 smoke alarms).
• The same fuse or circuit breaker must power all inter connected smoke alarms.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters). The interconnect wire
should be #18 gauge or larger, rated at least 300V. If an inter connect wire is not already part of your household wiring,
you will need to install one. This type of wire is commonly available at Hardware and Electrical Supply stores.
• All wiring must conform to all local electrical codes and Article 760 of the National Electrical Code (NFPA 70).
Refer to NFPA 72, Chapter 2 and/or your local building code for further connection requirements.

WEEKLY TESTING
WARNING!
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
you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one that has been Listed to
Underwriters Laboratories, Inc. Safety Standards, and use it only as directed. Use of non-UL Listed products or improper
use of UL Listed products may affect the smoke alarm’s sensitivity.
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.
(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 r eceiving
power and test it again. If it still does not alarm, replace it immediately.
pattern: 3 beeps, pause, 3 beeps, pause. When testing a series of inter connected units you must test each unit
individually. Make sur e all units alarm when each one is tested.
Press and hold the test button on the cover of the unit until the alarm sounds
During testing, you will hear a loud, repeating horn
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.
• Relocate the unit if it sounds frequent unwanted alarms. See “Wher e To Install Smoke Alarms.”
• When the battery back-up becomes weak, the smoke alarm unit will “chirp” about once a minute (the low
battery warning). This low battery warning should last for 7 days, but you should replace the battery immediately to
continue your protection.
Never use water, cleaners or solvents since they may damage the unit.
Choosing a replacement battery:
WARNING!
Use only the replacement batteries listed below. The battery back-up may not operate properly with other batteries.
Never use rechargeable batteries since they may not pr ovide a constant charge.
IMPORTANT!
The battery door will not close unless a battery is installed. This warns you the unit will not operate under DC power
without a battery .
Your smoke alarm’s battery back-up r equires one standard 9V battery. The following batteries are acceptable as replacements:
#216, #522 (Energizer), #1222
Eveready
batteries are available at many local retail stores. You may also use a Lithium battery like the Ultralife U9VL-J for longer service
life between battery changes. These batteries are available at many local retail stores.
Most carbon zinc batteries have an average service life of 1 year; most alkaline batteries have an average service life of 1-2
years; most Lithium batteries have an average service life of 6-10 years. 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.
Regardless of the manufacturer’s suggested battery life, you MUST replace the battery immediately once the unit starts
“chirping” (the “low battery warning”).

IF THIS SMOKE ALARM SOUNDS
WARNING!
• 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. If the unit alarms and you are not absolutely certain of the source of the smoke, get everyone out of
the house immediately.
•
N
ever disconnect the AC power to quiet an unwanted alarm. Disconnecting the power disables the alarm so
it cannot sense smoke. This will remove your protection. Instead open a window or fan the smoke away fr om
the unit. The alarm will reset automatically.
DANGER!
• ELECTRICAL SHOCK HAZARD: Attempting to disconnect the power connector from the unit when the
power is on may result in electrical shock, serious injury or death.
IMPORTANT!
When an interconnected system of AC powered units is in alarm, the alarm indicator light on the unit(s) that triggered the
alarm will blink rapidly . It will remain OFF on any remaining units.
Responding To An Alarm
During an alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.
If the unit alarms and you are not absolutely certain of the source of the smoke, get everyone out of the house immediately.
Stay calm and follow your family escape plan. Stay as low to the ground as possible, and cover your mouth with a damp cloth.
Never open a door before testing to see if it is hot. Call the Fire Department from outside, and give them your address then
name. Read “What To Do In Case Of Fire” at the end of this manual for more information.
If the unit alarms and you are certain that the source of smoke is not a fire—cooking smoke or an extremely dusty furnace—
open a nearby window or door and fan the smoke away from the unit. This will silence the alarm, and once the smoke clears the
unit will reset itself automatically .
IF Y OUR SMOKE ALARM IS NOT WORKING PROPERLY
If this unit is not working properly , there are a few simple things you should check before returning or replacing the unit:
• Make sure it is clean as described in “Regular Maintenance.” A build-up of dirt, dust or grease can affect the unit’s
performance.
• Make sure the unit is installed in a proper location. If you experience frequent unwanted alarms, try relocating it.
See “Where to Install Smoke Alarms” for details.
• Make sure it is receiving AC power from the household current.
• Check that the back-up battery is fresh and still providing back-up protection.
CAUTION!
Always discharge the branch circuit before servicing an AC or AC/DC smoke alarm. First, turn off the AC power at
the circuit breaker or fuse box. Next, remove the battery from smoke alarms with battery back-up. Finally, press
and hold the test button for 5-10 seconds to discharge the branch circuit.
