4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once AC power is applied, a fresh battery is installed and testing is complete. When products of combustion are sensed, the unit sounds a loud 85db pulsating alarm until the air is cleared.
HUSH CONTROL: The “HUSH” feature has the capability of temporarily desensitizing the alarm circuit for approximately 8 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 immediately and the red LED will flash every 2 seconds for approximately
8 minutes. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 8 minutes, and sound the alarm if smoke is still present. The “HUSH” feature can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the test/reset 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 INDICATORS: This smoke alarm is equipped with red and green LED indicators. The red LED is located under the test button and has several modes of operation. The green LED is located under the “Hush” button and indicates the presence of AC power.
Standby Condition: The red LED will flash every
Alarm Condition: When the alarm senses products of combustion and goes into alarm, the red LED will flash rapidly (once every two seconds). The rapid flashing LED and temporal alarm will continue until the air is cleared.
Hush Condition: The red LED will flash every 2 seconds as long as the alarm is in Hush mode.
