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 sensing chamber is cleared of smoke particles.
Smart HUSHTM Control: The Smart HUSHTM feature has the capability of temporarily desensi- tizing 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 HUSHTM control by pushing the but- ton on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immedi- ately. 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 automatically reset after approximately 7 minutes, and will sound again if particles of combustion are still pres- ent. The Smart HUSHTM 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® peri- od.
Remote HUSH® Control: Press the button on any Kidde Wireless device to activate the Smart HUSHTM feature on the Kidde Wireless smoke alarm that is initiating 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, activates 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 peri- od 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.
LED Indicator Operation
Red LED:
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.
Green LED:
The green LED will illuminate as described below under the following conditions: STANDBY CONDITION - The LED will flash approximately every 10 seconds. INITIATING ALARM INDICATOR The LED will flash every second while sounding an alarm to signify that the alarm sensed a smoke hazard. This will only be displayed on the alarms that sensed smoke. The remaining interconnected alarm(s) will sound but will not display the initiating indicator. The initiating indicator varies from model to model. See the user’s guide for each specific model of interconnected alarm for a description of the initiating alarm indicator.
