OPERATION
OPERATION AND TESTING
The smoke alarm is operating once the alarm is activated (see Installation Instructions)
and testing is complete. When products of combustion are sensed, the unit sounds a
loud 85db pulsating alarm until the air is cleared. If there is any question as to the
cause of the alarm, it should be assumed that the alarm is due to an actual fire and
the dwelling should be evacuated immediately.
HUSH
CONTROL: The HUSH
feature has the capability of temporarily desensitising
TM
TM
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 desensitised 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
slowly (1.5 seconds on - 8 seconds off) for 8 minutes. This indicates that the alarm is
in a temporarily desensitised condition. The smoke alarm will automatically reset after
approximately 8 minutes. If after this period particles of combustion are still present,
the alarm will sound again. The HUSH
TM
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 temporarily desensitised period.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH
TM
CONTROL FEATURE
AND SOUND A CONTINUOUS ALARM..
CAUTION: BEFORE USING THE ALARM HUSH
TM
FEATURE, IDENTIFY THE
SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
LED Indicator
This alarm is equipped with a red LED indicator, with four modes of operation.
Red LED - Flashing every 40-45 seconds: Indicates that the smoke alarm is receiving
power and operating properly.
Red LED - Flashing (1.5 second on - 1.5 second off): When the smoke alarm senses
particles of combustion and goes into alarm (constant pulsating sound), the red LED
will flash (approximately one flash per second). The flashing LED and pulsating alarm
will continue until the air is cleared.
Red LED - Flashing slowly (1.5 seconds on - 8 seconds off): Indicates that the unit is in
the Hush mode.
Red LED - Flashing rapidly when the test button is pressed: This unit features an
"alarm memory" to inform you if the alarm has sounded since the test button was
last pressed. The alarm memory will cause the red LED to flash rapidly when the test
button is pressed. The alarm memory is reset when the test button is released.
TESTING: Test by pushing the test button on the cover and holding it down for a
minimum of 5 seconds (or until the alarm sounds). This will sound the alarm if the
electronic circuitry, horn, and batteries are working. If no alarm sounds, the unit
has defective batteries or other failure. DO NOT use an open flame to test your
alarm, you could damage the alarm or ignite combustible materials and start a
structure fire.
NOTE: WEEKLY TESTING IS REQUIRED.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound
coming from your alarm may indicate a defective alarm, (see Warranty section).
