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, 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”.

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). 

During testing you will hear a loud, 

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

flashes.

During an alarm, you will hear a loud, repeating horn pattern: 

3 beeps, pause, 3 beeps, pause. Red LED flashes.

•  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.

•  Use the Silence feature to stop an unwanted alarm (caused by

cooking smoke, etc.), then open a window or fan the smoke

away from the unit. The Smoke Alarm will reset 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 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.

Install the MoUntIng Bracket:

1. Place the bracket on the wall or ceiling

where you want to mount the alarm.

2. Hold the mounting bracket against the

ceiling (or wall) and trace around the

inside of the two keyhole slots.

3. Make a mark inside each outline for

the drill holes.

4. Put the unit where it won’t get covered

with dust when you drill the mounting holes.

5. Using a 3/16-inch (5 mm) drill bit, drill a hole

through each

pencil mark.

6. 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.

7. Line the mounting bracket up over the plastic screw

anchors.

8. Screw the mounting bracket to the ceiling or wall

through the mounting slots using the two screws

provided.

9. Tighten both screws all the way.

UsIng the sIlence FeatUre

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 tempo-

rarily 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.

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 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 pack becomes weak, the Smoke Alarm unit will 

“chirp” about once a minute (the End of Life warning). This End of 

Life warning should last for 7 days, but you should replace the Smoke 

Alarm  

immediately to continue your protection.
