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.
SMART HUSH TM CONTROL: The SMART HUSH
ily desensitizing 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 desensitized by pushing the HUSH
alarm cover. If the smoke is not too dense, the alarm will silence immediately and the
red LED will illuminate for 1.5 seconds every 8 seconds for 8 minutes. This indicates
that the alarm is in a temporarily desensitized condition. The smoke alarm will auto-
matically reset after approximately 8 minutes and sound the alarm if particles of com-
bustion are still present. The SMART HUSH
air has been cleared of the condition causing the alarm. Pushing the test/reset button
on the alarm will end the temporarily desensitized period.
NOTE: DENSE SMOKE WILL OVERRIDE THE SMART HUSH
AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM SMART 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 1.5 seconds when the alarm is sounding.
• The LED will illuminate for 1.5 seconds every 8 seconds while the alarm is in the
temporarily desensitized mode.
• If alarm memory has been set (see below for alarm memory description), the LED
will flash rapidly when the test button is pressed.
ALARM MEMORY: This smoke alarm has an memory function that will 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 com-
ing from your alarm may indicate a defective alarm, and it should be returned for
service (see Section 11).
