4.OPERATION AND TESTING
OPERATION: The smoke alarm is operating once the alarm is activated (see Section 3)
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
TM
CONTROL: NOTE: Hush control and test button are a single button. The
HUSH
TM
feature has the capability of temporarily desensitising the alarm circuit for
approximately 10 minutes. This feature is to be used only when a known alarm con-
dition, such as smoke from cooking, activates the alarm. The smoke alarm is desensi-
tised by pushing the HUSH
®
button on the smoke alarm cover. The alarm will silence
immediately, and the LED will flash every 10 seconds to signal that the alarm is in
Hush mode. The smoke alarm will automatically reset after approximately 10 minutes.
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.
CAUTION: BEFORE USING THE ALARM HUSH
TM
FEATURE, IDENTIFY THE
SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
FLASHING LED LIGHT: This smoke alarm is equipped with a flashing red indicator light
with the following modes of operation:
• The LED will flash every every 60-70 seconds in the standby mode signifying that
the alarm is receiving power.
• The LED will flash every 0.5 seconds when the alarm is sounding. The flashing LED
and pulsating alarm will continue until the air is cleared.
• The LED will flash every 10 seconds while in Hush mode.
• The LED will flash twice every 30 seconds when the alarm is within 30 days of end
of life.
• The LED will flash every 30 seconds (with a chirp every 60 seconds) when the alarm
is at end of life. (replace alarm immediately)
• The alarm will chirp every 30 seconds without an LED flash to indicate a fault
condition with the processor of the alarm.
TESTING: Test by pushing the test/Hush button on the cover and holding it down for a
minimum of 1 second (or until the alarm sounds). Note: the first test sequence will
be at a lower volume. Holding the test/Hush button for longer than 5 seconds will
result in the full 85 decibel sound output. This will sound the alarm if the electronic
circuitry, horn, and battery are working. If no alarm sounds, the unit has a defective
battery 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.
SMOKE SENSING CHAMBER OPERATION: This alarm will "chirp" every 30 seconds
(with red LED flash at the same time) if it detects a problem with the smoke sensing
chamber.
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, and it should be returned for
service.
If your alarm regularly
nuisance alarms
(See Section 5) when cooking,
this indicates the alarm may be mounted too close to the source e.g..
kitchen. However, by pressing the
Hush
button prior to cooking, you can
densisitise the alarm for approximately 10 minutes.
