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 CONTROL: The HUSH
TM
sitising 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 desensitised by pushing the HUSH
cover. The alarm will silence immediately and the horn will chirp every 45 seconds for
10 minutes. This indicates that the alarm is in a temporarily desensitised condition.
The smoke alarm will automatically reset after approximately 10 minutes and sound
the alarm if particles of combustion are still present. The HUSH
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
CAUTION: BEFORE USING THE ALARM HUSH
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 four modes of operation:
• The LED will flash every 40-45 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.
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.
SMOKE SENSING CHAMBER OPERATION: This alarm will "chirp" if it detects a
problem with the smoke sensing chamber. This chirp will occur approximately 20
seconds after the flash of the LED.
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.
