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.
