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 com-
bustion, the horn will sound a loud (85db) temporal alarm until the sensing
chamber is cleared of smoke particles.
Smart HUSH
®
Control: The Smart HUSH
®
feature has the capability of temporari-
ly desensitizing the smoke sensing circuitry in order to quiet your alarm while
you take care of a non-emergency event. This feature is to be used only when a
known alarm condition, such as smoke from cooking, activates the alarm.
Activate Smart HUSH
®
control by pushing the button on the smoke alarm cover.
If the smoke is not too dense, the alarm will silence immediately. The green
LED will blink every 2 seconds for approximately 7 minutes to indicate that the
alarm is in a temporarily desensitized condition. The smoke alarm will automati-
cally reset after approximately 7 minutes, and will sound again if particles of
combustion are still present. The Smart 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.
Remote HUSH
®
Control: Press the button on any Kidde Wireless device to acti-
vate the Smart HUSH
®
feature on the Kidde Wireless smoke alarm that is initiat-
ing an alarm. This allows you to enable the Smart HUSH
®
feature on an alarm
that may be installed in an area that is difficult to reach. This feature should
only be used when a known alarm condition, such as smoke from cooking, acti-
vates the alarm.
Low Battery HUSH
®
Control: When the batteries need to be replaced, the unit
will produce a low battery “chirp” once per minute. The Low Battery HUSH
®
feature allows you to press the button on the alarm producing the warning and
disable the “chirp” for a random period of up to 12 hours. This gives you a
chance to replace the battery at a more convenient time without sacrificing your
safety by disconnecting the alarm from power. During this Low Battery HUSH
®
period your alarm is performing normally and is not desensitized.
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.
