To deactivate the battery carrier tamper resist, in order to change the smoke
alarm battery, remove the unit from the mounting plate, and locate the small
cut-out in the middle of the product label. Using a screwdriver, or similar tool,
slide the switch towards the bottom of the product label. The battery carrier can
now be opened and the battery changed.
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once fresh batteries are installed and
testing is complete. When the smoke alarm ionization chamber senses products
of combustion, the horn will sound a loud (85db) temporal alarm until the sens-
ing chamber is cleared of smoke particles.
Hush
®
CONTROL: The Hush
®
feature has the capability of temporarily desensi-
tizing the alarm circuit for approximately 7 minutes. This feature is to be used
only when a known alarm condition, such as smoke from cooking, activates the
alarm. The smoke alarm is desensitized by pushing the Hush
®
button on the
smoke alarm cover. If the smoke is not too dense, the alarm will silence immedi-
ately and “chirp” every 30-40 seconds for approximately 7 minutes. This indi-
cates that the alarm is in a desensitized condition. The smoke alarm will auto-
matically reset after approximately 7 minutes and sound the alarm if particles of
combustion are still present. The Hush
®
feature can be used repeatedly until the
air has been cleared of the condition causing the alarm. Pushing the test button
on the alarm will end the Hush
®
period.
NOTE: DENSE SMOKE WILL OVERRIDE THE Hush
®
CONTROL FEATURE
AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH
®
FEATURE, IDENTIFY THE
SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
LED INDICATOR: This smoke alarm is equipped with a red LED indicator with
two modes of operation.
Standby Condition: The red LED will flash every 30-40 seconds to indicate that
the smoke alarm is operating properly.
Alarm Condition: When the alarm senses products of combustion and goes
into alarm, the red LED will flash rapidly (one flash per
second). The rapid flashing LED and pulsating alarm will
continue until the air is cleared.
TESTING: Test by pushing the test button on the cover and hold it down for a
minimum of 5 seconds. This will sound the alarm if all the electronic circuitry,
horn and battery are working. If no alarm sounds, check the fuse or circuit
breaker supplying power to the alarm circuit. If the alarm still does not sound,
