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.

HOW TO INSTALL THIS SMOKE ALARM

THE PARTS OF THIS SMOKE ALARM

FOLLOW THESE SIMPLE STEPS

*All First Alert

®

 Smoke Alarms conform to regulatory requirements, 

including UL217 and are designed to detect particles of combustion. 

Smoke particles of varying number and size are produced in all fires.

Ionization technology is generally more sensitive than photo-

electric technology at detecting small particles, which tend to be 

produced in greater amounts by flaming fires, which consume 

combustible materials rapidly and spread quickly. Sources of 

these fires may include paper burning in a wastebasket, or a grease fire 

in the kitchen.

Photoelectric technology is generally more sensitive than ionization 

technology at detecting large particles, which tend to be produced 

in greater amounts by smoldering fires, which may smolder for 

hours before bursting into flame. Sources of these fires may include  

cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on each 

level and in every bedroom of your home.

•  This unit will not alert hearing impaired residents. It is recom-

mended that you install special units which use devices like 

flashing strobe lights to alert hearing impaired residents.

•  Do not connect this unit to any other Alarm or auxiliary 

device. It is a single-station unit that cannot be linked to other 

devices. Connecting anything else to this unit may prevent it 

from working properly.

•  Unit will not operate without battery power. The Smoke Alarm 

cannot work until you activate the battery power pack.

•  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.

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 flashes rapidly.

•  If the unit alarms get everyone out of the house immediately.

•  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 YOU SUSPECT A PROBLEM

Smoke Alarms may not operate properly because of a dead or weak  

battery, 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 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 Smoke 

Alarm.

•  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, make sure the 

power pack activating lever is pushed all the way securely.

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.

California State Fire Marshal (CSFM)

Early warning detection is best achieved by the installation of fire  

detection equipment in all rooms and areas of the household as follows: 

A Smoke Alarm installed in each separate sleeping area (in the vicinity, 

but outside bedrooms), and Heat or Smoke Alarms in the living rooms, 

dining rooms, bedrooms, kitchens, hallways, finished attics, furnace 

rooms, closets, utility and storage rooms, basements, and attached 

garages.

LOCATIONS TO AVOID FOR SMOKE ALARMS

For best performance, 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.

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”.

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.

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.

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.

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 9 minutes. To use this feature, press the 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 flash every 10 seconds 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.

TOOLS YOU WILL NEED:

This unit is designed to be mounted  

on the ceiling, or on the wall if necessary.

 

• Pencil 

 

•  Drill with 3/16” (5 mm) drill bit

 

•  Standard flathead screwdriver

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 30 days, but you should 

replace the Smoke Alarm immediately to continue your protection.

 

Actual service life depends on the Smoke Alarm and the environment  

in which it is installed. You MUST replace the Smoke Alarm immediately 

once the unit starts “chirping” (the “low battery 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. 

•  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/Silence button is the recommended way to 

test this Smoke Alarm. Press and hold the Test/Silence button on the 

cover of the unit until the alarm sounds (the unit may continue to alarm 

for a few seconds after you release the button). If it does not alarm, 

make sure the unit is receiving power and test it again. If it still does  

not alarm, replace it immediately. During testing you will hear a loud, 

repeating horn pattern: 3 beeps, pause, 3 beeps, pause. Red LED 

flashes rapidly.

WEEKLY TESTING

The optional locking feature is designed to prevent unauthorized removal of the alarm. It is not necessary to activate the lock in single-family 

households where unauthorized alarm removal is not a concern.  
Tools you will need:  Needle-nose pliers or utility knife • Standard flathead screwdriver

The feature uses a locking pin which is molded into the mounting bracket.  Remove locking pin by using needle-

nose pliers or a utility knife. 

To permanently remove the locking pin, insert a flathead screwdriver between the locking pin and the lock and pry the pin out of the lock.  

OPTIONAL LOCKING FEATURE

SILENCING THE LOW BATTERY WARNING

This silence feature can temporarily quiet the Low Battery warning “chirp”. 

Press the Test/Silence button on the Alarm. The Red light flashes normally, 

once every 6 minutes, during Low Battery Warning Silence.
After time, the low battery “chirp” will resume. 

Deactivate the Smoke 

Alarm and replace it immediately.

1.  Hold the mounting bracket against the ceiling (or wall) so the two 

clusters of universal mounting holes 

are aligned approximately at the 

9:00 and 3:00 o’clock positions. See 

image. Choose one of the three sets 

of holes shown, A, B or C (see image) 

and trace around one of the sets. Be 

sure to choose a top and bottom slot 

on opposite sides so you can rotate 

the universal mounting bracket into 

position later. This will make it easier 

in the future to remove the mounting 

bracket without completely removing 

the screws.  

WARNING! Do not install this Smoke Alarm over an existing  

electrical box. Only AC powered units are intended for  

installation over electrical boxes.

2.  Put the unit where it won’t get covered with dust when you drill 

the mounting holes.

3.  Using a 3/16” (5 mm) drill bit, drill a hole through the center of the 

oval outlines you traced.

4.  Insert the plastic screw anchors (in the plastic bag with screws) 

into the holes. Tap the screw anchors gently with a hammer, if 

necessary, until they are flush with the ceiling or wall.

5.  Install the screws but do not tighten completely. Attach the 

mounting bracket by aligning the screws in the open portion of 

the universal mounting slots and rotating the bracket into place. 

Tighten the screws until they are snug to secure the bracket.  

Do not over tighten.

6. 

Activating the battery. 

Mount alarm to mounting bracket to 

activate. Once unit is activated, it cannot be turned off.

NOTE: After you activate the battery, the power indicator light may 

flash. (If the unit alarms, the light will blink rapidly, and the horn 

will repeatedly sound 3 beeps, pause, 3 beeps.)

 

Once the Smoke 

Alarm is on the bracket, you can rotate the Alarm to adjust the 

alignment.

7.  Test the Smoke Alarm. See “Weekly Testing.”
8.  After 10 years of operation or Low Battery 

warning, deactivate the Smoke Alarm: Insert 

a tool below edge where shown and break 

tab. Then slide activation switch to deactivate mode.

NOTE: At end of life or low battery indication (chirp): unit must be 

put into deactivation mode to deactivate remaining stored energy 

in battery. Unit will no longer function once put into this mode. 

Unit will resist re-mounting.
