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 products or improper use of UL Listed products may affect
the smoke alarm's sensitivity.
Before using the alarm "test/silence" feature, identify the source of smoke or CO and be
certain that safe conditions exist.
FALSE ALARMS "TEST/SILENCE" CONTROL: Units with the "silence" feature have the capability
of temporarily reducing the sensitivity of the smoke alarm circuit for approximately 3-9 minutes. This
feature is to be used only when a known alarm condition such as smoke from cooking activates the
smoke alarm. The smoke alarm "silence" feature is activated by pushing the Test/Silence button on
the smoke alarm cover for at least three seconds. The smoke alarm will automatically reduce sensitivity
and the Red LED will flash on every 6 seconds and "beep" sounder approximately every 36 seconds
for approximately 3-9 minutes to indicate the alarm is in the temporary silent condition. The smoke
alarm will gradually regain normal sensitivity and sound the alarm if particles of combustion are still
present. The "silence" feature may be used repeatedly until the air has cleared.
MAINTENANCE: This combination alarm is virtually maintenance free. However, under dusty
conditions, a vacuum hose may be used to clear the sensing chamber of dust.
Clean the alarm at least once a month to remove dust, dirt or debris. Using a soft brush or wand
attachment to a vacuum cleaner, vacuum all sides and cover of alarm. Be sure all the vents are
free of debris.
END-OF-SERVICE LIFE NOTIFICATION: A majority of home fire deaths are a result of no smoke
alarms or no working smoke alarms. In addition to the “replace by date” stamped on the back of
your alarm, your alarm contains a unique audible end-of-service life notification feature. When it
is time to replace your alarm, which is approximately 7 years of operation, i.e. from initial power
up, the alarm will sound 4 chirps every 30 seconds and the yellow LED will blink on in synch with
the first chirp. The green LED stays on. This alarm signal cannot be reset. The alarm should be
replaced immediately.

STANDBY (NON-ALARM) CONDITION: Whenever battery power is present, the Green LED is
off and flashes on approximately every 40 seconds and the Red LED is off.
(ALARM) CONDITION: For BOTH the SMOKE and CO alarm conditions, the Red LED flashes
on
and the unit emits a loud, pulsating alarm (refer to the OPERATION section to differentiate
between the SMOKE and CO alarm patterns).
RESETTING YOUR ALARM: Reset your alarm by momentarily pushing the "TEST/SILENCE"
button.
END-OF-SERVICE LIFE CONDITION: When the alarm sounds 4 chirps every 30 seconds and
the yellow service light flashes 1 time during the first chirp, it indicates the “End-of-Service Life”
of the alarm. This alarm signal cannot be reset. The alarm should be replaced immediately.
The outside of the alarm can be wiped with a damp cloth.
Do not use any household cleaning
agents, ammonia-based cleaners, paints, varnishes or any other chemical on or near your alarm.
AFTER CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM BY USING THE TEST
BUTTON.
SERVICE CONDITION: Periodically, the alarm's circuitry is tested. If an error is detected, the
alarm will sound a double "beep" and the Yellow LED will flash
on twice approximately every 40
seconds. If this occurs, reset your alarm by momentarily pushing the "TEST/SILENCE" button.
If the smoke/CO alarm is false alarming or indicating service and cannot be restored to normal
operation, the alarm should be replaced.
