4. OPERATION AND TESTING

OPERATION

The smoke alarm is operating once A.C. power is applied, a fresh battery is 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 sensing chamber is

cleared of smoke particles.

Smart HUSH

CONTROL: The Smart HUSH

feature has the capability of temporarily desensitizing the smoke sensing circuitry

for approximately 7 minutes to quiet your alarm while taking 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. The smoke alarm is desensitized by pushing the Smart

HUSH

button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and the green LED will

blink every 2 seconds for approximately 7 minutes. This indicates that the alarm is in a temporarily desensitized condition. The smoke

alarm will automatically reset after approximately 7 minutes and sound the alarm 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: Press the button on any wireless device to activate the Smart Hush® on a wireless smoke alarm that is initiating an

alarm. This allows you to enable the Smart HUSH™ feature on a Kidde Wireless smoke 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, activates the alarm.

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.

Low Battery Hush: When the battery needs to be replaced, the unit will produce a low battery “chirp” once per minute. The Low

Battery HUSH allows you to press the button on the alarm producing the warning and disable the “chirp” for 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.

The red LED will flash in conjunction with the alarm beep. Therefore, the red LED will flash during a smoke alarm, a low battery

mode chirp and a unit error mode chirp.
