• 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 prod-

ucts or improper use of UL Listed products may affect the Smoke

Alarm’s sensitivity.

• 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 horn is sounding.

Exposure at close range may be harmful to your hearing. When

WEEKLY TESTING

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. During testing, you will hear a loud, repeating horn pattern:

3 beeps, pause, 3 beeps, pause.

You can test this Smoke Alarm two ways:

Manually:

Press the Test/Silence button on the

alarm cover until alarm sounds for 3-5 seconds.

Using Your Remote Control: Standing no fur-

ther than 20 feet away from the Smoke Alarm,

aim your IR remote at the Smoke Alarm and

press the CHANNEL or VOLUME button for at

least 3-5 seconds.

If the alarm does not respond to your remote

control, there may be an obstruction between

you and the alarm, you may be standing too

far away, or your remote control may not be

compatible.

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you activate the battery and

test the Smoke Alarm.
