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 10
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 10 seconds
for approximately 10 minutes. This indicates that the alarm is in a
temporarily desensitized condition. The smoke alarm will automati-
cally reset after approximately 10 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.
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 but-
ton 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
approximately every 45 seconds to
indicate that the smoke alarm is
operating properly. The green LED will
be steady on, indicating the presence
of AC power.
Alarm Condition: When the alarm senses products of
combustion and goes into alarm, the
red LED will flash rapidly (once every
second). The rapid flashing LED
and temporal alarm will continue until
the air is cleared.
