Smoke alarms are designed to minimize nuisance alarms.

Cigarette smoke will not normally set off the alarm, unless

the smoke is blown directly into the alarm.

Combustion particles from cooking may set off the alarm if

the alarm is located close to the cooking area. Large

quantities of combustible particles are generated from

spills or when broiling. Using the fan on a range hood

which vents to the outside (non-recirculating type) will also

help remove these combustible products from the kitchen.

If the alarm does sound, check for fires first. If a fire is

discovered, get out and call the fire department. If no fire is

present, check to see if one of the reasons listed in Section

2 may have caused the alarm.

6. MAINTENANCE

BATTERY REPLACEMENT

To replace the battery, remove the alarm from the mounting

bracket by rotating the alarm counterclockwise.

The Smoke Alarm is powered by a 9V carbon zinc battery

(alkaline and lithium batteries may also be used). A fresh

battery should last for one year under normal operating

conditions. This alarm has a low battery monitor circuit

which will cause the alarm to "chirp" approximately every

30 - 40 seconds for a minimum of seven (7) days,

accompanied by the red LED flash, when the battery gets

low.

Replace the battery when this condition occurs.

CLEANING YOUR ALARM

To clean your alarm, remove it from the mounting bracket

as outlined in the beginning of this section. You can clean

your alarm by using compressed air or your vacuum

cleaner hose to blow or suck air through the openings

around the perimeter of the alarm. The outside of the alarm

can be wiped with a damp cloth.

After cleaning, reinstall your alarm. Test your alarm by

using the test button.

7. LIMITATIONS OF SMOKE ALARMS

WARNING:

PLEASE

THOROUGHLY

Smoke alarms are devices that can provide early warning

of possible fires at a reasonable cost; however, alarms

have sensing limitations. Ionization type alarms offer a

broad range of fire sensing capabilities but are better at

detecting fast flaming fires than slow smoldering fires.

Photoelectric alarms sense smoldering fires better than

flaming fires. Home fires develop in different ways and are

often unpredictable.

Neither type of alarm (photoelectric or ionization) is always

best, and a given alarm may not always provide warning of

a fire.

• A battery powered alarm must have a battery of the

specified type, in good condition and installed properly.

• A.C. powered alarms will not operate if the A.C. power

has been cut off, such as by an electrical fire or an open

fuse.

• Smoke alarms must be tested regularly to make sure the

DG332Manual

READ

CAREFULLY

batteries and the alarm circuits are in good operating

condition.

• Smoke alarms cannot provide an alarm if smoke does not

reach the alarm. Therefore, smoke alarms may not sense

fires starting in chimneys, walls, on roofs, on the other side

of a closed door or on a different floor.

• If the alarm is located outside the bedroom or on a

different floor, it may not wake up a sound sleeper.

• The use of alcohol or drugs may also impair one's ability

to hear the smoke alarm. For maximum protection, a smoke

alarm should be installed in each sleeping area on every

level of a home.

• Although smoke alarms can help save lives by providing

an early warning of a fire, they are not a substitute for an

insurance policy. Home owners and renters should have

adequate insurance to protect their lives and property.

8. GOOD SAFETY HABITS

DEVELOP AND PRACTICE A PLAN OF ESCAPE

• Make a floor plan indicating all doors and windows and at

least two (2) escape routes from each room. Second story

windows may need a rope or chain ladder.

• Have a family meeting and discuss your escape plan,

showing everyone what to do in case of fire.

• Determine a place outside your home where you all can

meet if a fire occurs.

• Familiarize everyone with the sound of the smoke alarm

and train them to leave your home when they hear it.

• Practice a fire drill at least every six months. Practice

allows you to test your plan before an emergency. You may

not be able to reach your children. It is important they know

what to do.

WHAT TO DO WHEN THE ALARM SOUNDS

• Leave immediately by your escape plan. Every second

counts, so don't waste time getting dressed or picking up

valuables.

• In leaving, don't open any inside door without first feeling

its surface. If hot, or if you see smoke seeping through

AND

cracks, don't open that door! Instead, use your alternate exit.

If the inside of the door is cool, place your shoulder against

it, open it slightly and be ready to slam it shut if heat and

smoke rush in.

• Stay close to the floor if the air is smoky. Breathe

shallowly through a cloth, wet if possible.

• Once outside, go to your selected meeting place and

make sure everyone is there.

• Call the fire department from your neighbor's home - not

from yours!

• Don't return to your home until the fire officials say that it

is all right to do so.

There are situations where a smoke alarm may not be

effective to protect against fire as stated in the NFPA

Standard 72. For instance:

a) smoking in bed

b) leaving children home alone
