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-
intest switch accurately tests the unit’s operation as required by
Underwriters Laboratories, Inc. (UL).
• 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” at the end of this manual.
DO NOT stand close to the Alarm when the hornis 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/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 surethe 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. LED flashes once every second.
When testing a series of interconnected units you must test each unit
individually.Make sureall units alarm when each one is tested.

REGULAR MAINTENANCE

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.
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 the
outside of the Smoke Alarm using your household vacuum’s soft brush
attachment. 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
ToAvoid For Smoke Alarms” for details.
• When the batteries become 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 batteries immediately to continue your
protection.

Choosing a replacement battery:
Your Smoke/CO Alarm requires two “AA” Energizer E91 batteries.
These batteries are available at many local retail stores.
Actual battery service life depends on the 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”).
Toreplace the batteries (without removing Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram
and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals on the
ends of the batteries with the terminals on
the unit.
4. Close the battery compartment, and then
test the unit by pressing the Test/Silence
button.

RESPONDING TO AN ALARM

During an alarm, you will hear a loud, repeating horn pattern: 3 beeps,
pause, 3 beeps, pause.
•If the unit alarms and you are not testing the unit, it is warning you of a
potentially dangerous situation that requires your immediate attention.
NEVER ignoreany alarm. Ignoring the alarm may result in injury or
death.
•Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the Alarm so it cannot sense smoke. This will
remove 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.
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 (Use the Silence Feature
to silence the Alarm). This will silence the alarm, and once the smoke clears the
unit will reset itself automatically.

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 beforeopening 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.
