CHAPTER 4: TESTING AND MAINTENANCE
WEEKLY TESTING
• SMOKE ALARM: NEVER use an open flame of
any kind to test the Smoke Alarm. 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.
• CO ALARM: NEVER use vehicle exhaust to test
the CO Alarm. Exhaust may cause permanent
damage and voids your 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/Silence
button is the recommended way to test this Alarm.
1.
Push and hold the Test/Silence button on the cover
until you hear a “chirp.” The “chirp” marks the start
of the self-test sequence.
2. During testing, you will hear a loud, repeating horn
pattern: 3 beeps, pause, 3 beeps, pause, while the
red smoke LED flashes. Then you will hear a loud,
repeating horn pattern: 4 beeps, pause, 4 beeps,
pause, while the red CO LED flashes.
3. When testing a series of interconnected units you
must test each unit individually. Make sure all units
alarm when each one is tested.
If the Smoke/CO Alarm does not test properly:
1. Make sure the AC power is applied and battery is
fresh and installed correctly.
2. Be sure the alarm is clean and dust-free.
3. Test the unit again.
If the Smoke/CO Alarm is still not working properly,
replace it immediately. Refer to the “Limited Warranty”
at the end of this manual.
If there is still a problem, do not try to fix the Alarm
yourself. This will void your warranty!
