Smoke Alarms

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.

Other Features of 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. Units must be installed by a qualified

electrician.

AC/DC powered smoke alarms: (AC with battery back-

up):

Can be interconnected so if one unit senses smoke, all

units alarm. They will operate if electricity fails, provided the

batteries are fresh and correctly installed. Units must be

installed by a qualified electrician.

Smoke alarms for the hearing impaired:

Special purpose

smoke alarms should be installed for the hearing

impaired.

They include a visual alarm and an audible alarm

horn, and meet the requirements of the Americans With

Disabilities Act. These units can be interconnected so if one

unit senses smoke, all units alarm. They do not operate if

electricity fails. Units must be installed by a qualified

electrician.

Cat. 100S is an AC powered

unit that has an 85 decibel alarm and a 177 candela strobe

light, which flashes rapidly when the unit is in alarm.

All these units 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 unit 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

Where To Install Smoke Alarms

Installing Smoke Alarms in Single-Family And Multi-Family Residences

The National Fire Protection Association (NFPA), recommends one smoke alarm on every floor, in every sleeping area, and in

every bedroom. In new construction, the smoke alarms must be AC powered and interconnected. See “Agency Placement

Recommendations” for details. For additional coverage, it is recommended that you install a smoke alarm in all rooms, halls,

storage areas, finished attics, and basements, where temperatures normally remain between 40˚F (4˚C) and 100˚F (38˚C). Make

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

More specifically, install smoke alarms:

• On every level of your home, including finished

attics and basements.

• Inside every bedroom, especially if people

sleep with the door partly or completely closed.

• In the hall near every sleeping area. If your

home has multiple sleeping areas, install a unit

in each. If a hall is more than 40 feet long (12

meters), install a unit at each end.

• At the top of the first-to-second floor stairway,

and at the bottom of the basement stairway.

IMPORTANT!

Specific requirements for smoke alarm installation

vary from state to state and from region to region.

Check with your local Building Inspector and/or Fire

Department for current requirements in your area.

If you install AC or AC/DC units, it is recommended

(and may be required) 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)

.

IMPORTANT!

This equipment should be installed in accordance

with the National Fire Protection Association’s

Standard 72.

National Fire Protection Association,

One Batterymarch Park, Quincy, MA 02269-9101.

Additional local building and regulatory codes

may apply in your area. Always check

compliance requirements before beginning any

installation.

Smoke Alarms Recommended In Hotels, Motels,

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 basement, 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 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, sau-

nas, 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 open-

ings to the sensing chamber and cause

unwanted alarms.

• Less than 12 inches (305 mm) away from fluo-

rescent lights. Electrical “noise” can interfere

with the sensor.

•

In “dead air” spaces. “Dead air” spaces may

prevent smoke from reaching the smoke alarm

.

4

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 inches (102 mm) and 12 inches (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.

Important! Read Before You Install This 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

area where you will install this unit at the circuit

breaker or fuse box before beginning installation.

Failure to turn off the power before installation may

result in serious electrical shock, injury or death.

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.

WARNING!

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.

WARNING!

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

.

WARNING!

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.

WARNING!

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.

WARNING!

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.

6

CAUTION!

Connect this unit ONLY to other compatible units.

See “How To Install and Interconnect 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.

CAUTION!

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.

CAUTION!

Do not paint over the unit. Paint may clog the

openings to the sensing chamber and prevent the

unit from operating properly.

CAUTION!

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.

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.

Interconnecting Multiple

Smoke Alarms

Interconnected units can provide earlier warning of

fire than stand-alone units, especially if a fire starts

in a remote area of the dwelling. If any unit in the

series senses smoke, all units will alarm. To

determine which smoke alarm initiated an alarm, see

table:

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.

WARNING!

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.

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.

returns to normal operation.

Testing and Maintenance

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.

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 immediately.

During

testing, you will hear a loud, repeating horn

pattern: 3 beeps, pause, 3 beeps, pause.

When testing a series of interconnected units you

must test each unit individually. Make sure all units

alarm when each one is tested.

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.

• Gently vacuum off any dust on the cover at

least once a month using your vacuum’s soft

brush attachment. Test the unit after vacuum-

ing the cover.

• Never use water, cleaners or solvents since

they may damage the unit.

• Relocate the unit if it sounds frequent

unwanted alarms. See “Where Not To Install

Smoke Alarms” for details.

• When the battery back-up becomes weak, the

smoke alarm will “chirp” about once a minute

(the low battery warning). This warning should

last 7 days, but you should replace the battery

immediately to continue your protection.

Choosing a replacement battery:

Your smoke alarm’s battery back-up requires one

standard 9V battery. The following batteries are

acceptable as replacements. This list supplements

the list on the smoke alarm battery door: Eveready

#216, #522 (Energizer), #1222; Duracell #MN1604,

MX1604 (Ultra); Gold Peak #1604P, #1604S;

Rayovac 1604, D1604. 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.

15

IMPORTANT!

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

If the alarm sounds and you are not testing it, it is

warning you of a potentially dangerous situation

that requires your immediate attention.

WARNING!

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.

Responding To An Alarm

If the unit alarms and you are not absolutely certain of

the source of the smoke, get everyone out of the

dwelling 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, for example—open a

nearby window or door and fan the smoke away

from the unit (Model 4120SB only: use the Silence

Feature to silence the alarm). This will silence the

alarm, and once the smoke clears the unit will reset

itself automatically.

N

OTE:

When an interconnected system of AC powered units

is in alarm, the alarm indicator light on the unit(s) that

initiated the alarm will blink rapidly. It will remain OFF

on any remaining units.

CAUTION!

Never disconnect the AC power to quiet an

unwanted alarm. Disconnecting the power disables

the alarm so it cannot sense smoke. This will

remove your protection.

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.

16

Cat. 4120SB Only—

Using The Silence Feature

The silence feature on this unit can temporarily quiet

an unwanted alarm for several minutes.

CAUTION!

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 a fire can result in property loss,

injury, or death.

IMPORTANT!

While the unit is in the “silence mode,” the test

button will not operate. The alarm cannot be tested

while in the silence mode.

To silence smoke alarms

in an interconnected series:

1. To silence multiple alarms in an interconnected

series, you must press the silence button on the

unit(s) that triggered the alarm.

N

OTE:

The red light under the silence button on the initiating

alarm will flash rapidly. The red light will be off on all

other smoke alarms.

2. Once you activate the silence feature, you will

hear a reminder “chirp” on the initiating alarm

about once a minute (for up to 15 minutes).

3. While the units are in the “silence mode,” the test

buttons will not operate. The alarms cannot be

tested while in the silence mode.

4. The “chirping” on the initiating alarm will stop

once the unit returns to normal operation.

IMPORTANT!

The silence feature on these units can temporarily

quiet an unwanted alarm fo several minutes. To use

this feature, press the “Push to Silence” button on

the cover. Once you activate it, you will hear a

reminder “chirp” about once a minute (for up to 15

minutes) and the Test feature is temporarily

disabled. The “chirping” will stop once the unit

returns to normal operation.

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

.

Protecting Your Family From Fire

Putting up smoke alarms is just one step in

protecting your family from fires. You must also

reduce the chance a fire will start in your dwelling,

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 residence 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

residence, and make sure everyone knows to wait

there; 3) Know where to go to call the Fire

Department from outside the residence; 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 residence

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 dwelling and/or dwelling unit, 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) 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 free from grease and debris; 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

allow rubbish to accumulate.

18

What To Do

In Case Of Fire

• Don’t panic; stay calm. Follow your escape

plan. Your safe escape may depend on thinking

clearly and remembering what you have prac-

ticed.

• Get out of the dwelling as quickly as possible.

Don’t stop to get dressed 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 (pref-

erably 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

everyone 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 more ideas on

making your home safer, and on creating your own

family escape plan.

If Your Smoke Alarm

Needs Service

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.

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 units performance.

• Make sure the unit is installed in a proper loca-

tion. 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.

If the unit is still not operating properly, and it is

still under warranty, send it, shipping prepaid to:

BRK Brands, Inc., Attn: Consumer Affairs, 3920

Enterprise Court, Aurora, IL 60504-8132. Enclose a

note in the package describing what’s wrong with

the unit. See warranty information at the end of this

manual.

CAUTION!

Do not try to fix the unit yourself—this will void your

warranty!

Special Compliance Considerations

WARNING!WARNING!WARNING!

This unit alone is not a suitable substitute for complete fire detection systems in places housing many

people—like apartment buildings, condominiums, hotels, motels, dormitories, hospitals, long-term health

care facilities, nursing homes, day care facilities, or group homes of any kind—even if they were once single-

family homes. It is not a suitable substitute for complete fire detection systems in warehouses, industrial

facilities, commercial buildings, and special-purpose non-residential buildings which require special fire

detection and alarm systems. Depending on the building codes in your area, this unit 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 powered smoke alarms only.

AC, AC/DC, or DC powered smoke alarms can be

used in existing construction 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 “households.”

Single-Family Residence:

Single family dwelling, townhouse.

Multi-Family or Mixed Occupant Residence:

Apartment building, condominium. This type of unit

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 type of unit in common areas may not

provide sufficient warning to all residents or meet

local fire protection ordinances/regulations.

Institutions:

Hospitals, day care facilities, long-term health care

facilities. This type of unit 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 type of

unit in common areas may not provide sufficient

warning to all residents or meet local fire protection

ordinances/regulations.

Hotels/Motels:

Also boarding houses and dormitories. This type of

unit 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 type of unit in

common areas may not provide sufficient warning to

all residents or meet local fire protection ordinances/

regulations.

21

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 reach the sensing chamber and set off the

alarm. That is why one unit should be installed inside

each bedroom or sleeping area—especially if

bedroom or sleeping area doors are closed at night—

and in the hallway between them.

Smoke alarms may not detect fire on another floor

or area of the dwelling. For example, a stand-alone

unit on the second floor may not detect smoke from a

basement fire until the fire spreads. This may not give

you enough time to escape safely. That is why

recommended minimum protection is at least one unit

in every sleeping area, and every bedroom on every

level of your dwelling. Even with a unit on every floor,

stand-alone units may not provide as much protection

as interconnected units, especially if the fire starts in a

remote area. Some safety experts recommend

installing interconnected AC powered units with

battery back-up (see “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 UL

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 manufacture. See back of

smoke alarm for manufacture date.
