cover. If the smoke is not too dense, the alarm will silence immedi-
ately and the red LED will flash every 2 seconds for approximately
8 minutes. This indicates that the alarm is in a temporarily desensi-
tized 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, IDEN-
TIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE
CONDITION EXISTS.
LED INDICATOR: This smoke alarm is equipped with a red LED indi-
cator. The red LED is located under the test button and has several
modes of operation.
Standby Condition:
The red LED will flash every 30-40
seconds to indicate that
the smoke alarm is operating properly.
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.
Low Battery Condition:
The red LED flash will be accompanied
by an audible chirp. Replace the battery
when this condition occurs.
SMOKE SENSING CHAMBER OPERATION: This alarm will “chirp” if
any of the components in the smoke sensing chamber fail. This
chirp will occur between the flashes of the red LED indicator light.
(If the chirp occurs at the same time as the red LED flash, see sec-
tion 6 for low battery information).
TESTING: Test by pushing the test button on the cover and hold it
down for a minimum of 5 seconds. This will sound the alarm if the
electronic circuitry and horn and battery are working. If no alarm
sounds, the unit has defective batteries or other failure. DO NOT
