All First Alert®Smoke Alarms conform to regulatory requirements,

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 elec-

trical circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys

grease- and debris-free; 6) Never leave anything cooking on the stove

unattended; 7) Keep portable heaters and open flames, like candles,

away from flammable materials; 8) Don’t let rubbish accumulate.

Keep alarms clean, and test them weekly. Replace alarms immediately if

they are not working properly. Smoke Alarms that do not work cannot alert

you to a fire. Keep at least one working fire extinguisher on every floor, and

an additional one in the kitchen. Have fire escape ladders or other reliable

means of escape from an upper floor in case stairs are 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 mon-

itors 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, main-

tained 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.

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 of Canada

(ULC).

• 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”.

• 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 and test it again. If it still does not alarm, replace it imme-

diately. During testing you will hear 3 beeps, pause, 3 beeps.

HOW TO INSTALL THIS SMOKE ALARM

THE PARTS OF THIS SMOKE ALARM

FOLLOW THESE SIMPLE STEPS

Tools you will need:

• Pencil

• Drill with 5 mm (3/16”) drill bit

• Standard Flathead screwdriver

• Hammer

1. Remove the mounting bracket from the Smoke Alarm base. Hold

the mounting bracket against the ceiling (or wall) and make a mark

at the center of each of the mounting slots with a pencil.

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

mounting holes.

3. Using a 5 mm (3/16”) drill bit, drill a hole through each pencil mark.

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. Tighten the screws (provided) into the screw anchors.

• 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 the 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 install the battery in the correct

position (Match “+” to “+” and “-” to “-”).

• This Smoke Alarm has a battery drawer which resists closing

unless a battery is installed. This warns you the unit will not

operate without a battery.

• 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.

6. Activate the battery. With the

battery compartment open,

install the battery so the

terminals on the battery match

the terminals on the Smoke

Alarm. Match “+” to “+” and

“-” to “-.” Push the battery in

until it snaps in securely and

cannot be shaken loose.

If the battery is not snapped in completely, the unit cannot receive

battery power. The Smoke Alarm may beep briefly when you install

the battery—this is normal.

Position the base of the Smoke Alarm over the mounting bracket and

turn. The Alarm can be positioned over the bracket every 60°. Turn

the Smoke Alarm clockwise (right) until the unit is in place.

8. Test the Smoke Alarm. See “Weekly Testing.”

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.

Use only the replacement batteries listed below. The unit may not

operate properly with other batteries. Never use rechargeable

batteries since they may not provide a constant charge.

• Test it at least once a week.

• Clean the Smoke Alarm at least once a month; gently vacuum the

outside of the Smoke Alarm using your household vacuum’s soft

brush attachment. A can of clean compressed air (sold at computer

or office supply stores) may also be used. Follow manufacturer

instructions for use. Test the Smoke Alarm. 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”

about once a minute (the low battery warning). This low battery warn-

ing should last for 30 days, but you should replace the battery imme-

diately to continue your protection.

Choosing a replacement battery:

Your Smoke Alarm requires one standard 9V battery. The following

batteries are acceptable as replacements: Eveready #1222, Duracell

#MN1604, (Ultra) #MX1604; Eveready (Energizer) #522. 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.

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 intercon-

nected. See “Agency Placement Recommendations” for details. For addi-

tional coverage, it is recommended that you install a Smoke Alarm in all

rooms, halls, storage areas, finished attics, and basements, where tem-

peratures normally remain between 4˚ C (40˚ F) and 38˚ C (100˚ F). Make

sure no door or other obstruction could keep smoke from reaching the

Smoke Alarms.

More specifically, install Smoke Alarms:

•

On every level of your home, including finished attics and basements.

• Inside every bedroom, especially if people sleep with the door partly

or completely closed.

• In the hall near every sleeping area. If your home has multiple

sleeping areas, install a unit in each. If a hall is over 12 meters

(40 feet) 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 by municipality

and province. 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.

SPECIAL COMPLIANCE CONSIDERATIONS

This Smoke Alarm alone is not a suitable substitute for complete fire

detection systems in places housing many people—like apartment build-

ings, condominiums, hotels, motels, dormitories, hospitals, long-term

health care facilities, nursing homes, day care facilities, or group homes

of any kind—even if they were once single-family homes. It is not a suit-

able substitute for complete fire detection systems in warehouses, indus-

trial 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.

The following information applies to all four building types below:

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 101 (Life Safety Code) or NFPA 72 (National Fire

Alarm Code), local building codes, or consult your Fire Department for

detailed fire protection requirements in buildings not defined as “house-

holds.”

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 sys-

tem 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.

3. Institutions:

Hospitals, day care facilities, long-term health care facilities. This

Smoke Alarm is suitable for use in individual patient sleeping/resident

rooms, 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 suf-

ficient warning to all residents or meet local fire protection

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

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.

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 imme-

diately 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.

456

INSTALLING SMOKE ALARMS IN MOBILE HOMES & RVS

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 4˚ C (40˚ F) and 38˚ C (100˚ F). WARNING: Test units

used in RVs after the vehicle has been in storage, before every trip,

and once a week while in use. Failure to test units used in RVs as

described may remove your protection.

This equipment should be installed in accordance with NFPA (National Fire

Protection Association) 72 and

101. National Fire Protection Association, One

Batterymarch Park, Quincy, MA 02269-9101

U.S.A

. Additional local build-

ing and regulatory codes may apply in your area. Always check com-

pliance requirements before beginning any installation.

This model is

not RV listed with Underwriters’ Laboratories of Canada (ULC).

AGENCY PLACEMENT RECOMMENDATIONS

NFPA 72 (National Fire Code)

Smoke Alarms shall be installed in each separate sleeping room, outside

each sleeping area in the immediate vicinity of the bedrooms and on

each additional story of the family living unit, including basements and

excluding crawl spaces and unfinished attics.

In new construction, Alarms shall be so arranged that operation of any

one Alarm shall cause the operation of all Alarms within the dwelling.

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 recommended that

the householder consider the use of additional Smoke Alarms for those

areas for increased protection. The additional areas include the base-

ment, bedrooms, dining room, furnace room, utility room, and hallways

not protected by the required Smoke Alarms. The installation of Smoke

Alarms in kitchens, attics (finished or unfinished), or garages is not

normally recommended, as these locations occasionally experience con-

ditions that can result in improper operation.

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 6 meters

(20 feet) from the sources of combustion particles (stove, furnace,

water heater, space heater) if possible. In areas where a 6 meter

(20-foot) distance is not possible – in modular, mobile, or smaller

homes, for example – it is recommended the Smoke Alarm be

placed as far from these fuel-burning sources as possible. The

placement recommendations are intended to keep these Alarms at

a reasonable distance from a fuel-burning source, and thus reduce

“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm

is placed directly next to a fuel-burning source. Ventilate these areas

as much as possible.

• In air streams near kitchens. Air currents can draw cooking smoke

into the sensing chamber of a Smoke Alarm near the kitchen.

• In very damp, humid or steamy areas, or directly near bathrooms with

showers. Keep units at least 3 meters (10 feet) away from showers,

saunas, dishwashers, etc.

• Where the temperatures are regularly below 4˚ C (40˚ F) or above

38˚C (100˚ F), 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 305 mm (12 inches) 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

102 mm (4 inches) from the wall or corner.

For wall mounting (if allowed by building codes), the top edge of Smoke

Alarms should be placed between 102 mm (4 inches) and 305 mm (12 inch-

es) from the wall/ceiling line, below typical “dead air” spaces.

On a peaked, gabled, or cathedral ceiling, install the first Smoke

Alarm within 0.9 meters (3 feet) 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.

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.

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 Code) and NFPA 101 (Life Safety

Code). National Fire Protection Association, One Batterymarch Park,

Quincy, MA 02269-9101 U.S.A. Local building codes may also require

specific units in new construction or in different areas of the home.

IF THIS SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM

During an alarm, you will hear 3 beeps, pause, 3 beeps.

• 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.

OPTIONAL LOCKING FEATURES

The locking features are designed to discourage 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 or utility knife • Standard Flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Using needle nose pliers or a utility

knife, remove one or both pins from the mounting bracket, depending on how many locking features you want to use.

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

Locking Pin

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you have installed the

battery and tested the unit.

1. Push and hold test button until the alarm sounds a loud 3 beeps,

pause 3 beeps.

If the unit does not alarm during testing,

DO NOT lock the battery compartment!

Install a new battery and test again. If the

Smoke Alarm still does not alarm, replace it

immediately.

2. Using needle-nose pliers or a

utility knife, detach one locking

pin from the mounting bracket.

3. Push the locking pin through

the black dot on the label on

the back of the Smoke Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

1. Remove the Smoke Alarm from the mounting bracket. If the unit is

locked to the bracket, see the section “To Unlock the Mounting

Bracket.”

2. Insert a flathead screwdriver under the

head of the locking pin, and gently pry it

out of the battery compartment lock. (If

you plan to relock the battery

compartment, save the locking pin.)

3. To relock the battery compartment, close the battery door and

reinsert locking pin in lock.

4. Reattach the Smoke Alarm to the mounting bracket.

When replacing the battery, always test the Smoke Alarm before relock-

ing the battery compartment.

TO UNLOCK THE MOUNTING BRACKET

1. Insert a flathead screwdriver between the

mounting bracket pin and the mounting

bracket.

2. Pry the Smoke Alarm

away from the

bracket by turning

both the screwdriver

and the Smoke Alarm

counterclockwise

(left) at the same

time.

TO LOCK THE MOUNTING BRACKET

1. Using needle-nose pliers, detach one locking pin from mounting bracket.

2. Insert the locking pin into the lock located on the pivoting hinge of

the battery door.

3. When you attach the Smoke Alarm to the mounting bracket, the

locking pin’s head will fit into a notch on the bracket.

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.

REGULAR MAINTENANCE, Continued

Actual battery 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”).

USING THE SILENCE FEATURE (MODEL SA303A ONLY)

The Silence Feature can temporarily quiet an unwanted alarm for up to 10

minutes. To use this feature, press the “Test/Silence” button. The Alarm

remains functional. The LED will flash every 10 seconds (for up

to 10 minutes) to remind you the alarm has been silenced. The flashing

LED will stop when the unit returns to normal operation.

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, it 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.
