4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once A.C. power is applied, a fresh
battery is installed and testing is complete. When the smoke alarm ionization
chamber senses products of combustion, the horn will sound a loud (85db) tem-
poral alarm until the sensing chamber is cleared of smoke particles.

CONTROL: The “HUSH” feature has the capability of temporarily desen-
sitizing the alarm circuit for up to 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 “TEST/HUSH” button on
the smoke alarm cover. If the smoke is not too dense, the alarm will silence
immediately. The red LED will illuminate for 1.5 seconds every 8-10 seconds
while in hush. This indicates that the alarm is in a temporarily desensitized
condition. The smoke alarm will automatically reset after approximately 8 min-
utes and sound the alarm if particles of combustion are still present. The
“HUSH” feature can be used repeatedly until the air has been cleared of the
condition causing the alarm. Pushing the Test/Hush button on the alarm will end
the hush period.
This alarm has a low battery HUSH feature. If the alarm is sounding a low bat-
tery warning chirp, you can silence this chirp for approximately 13 hours by
pressing the Test/Hush button.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEATURE AND
SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH FEATURE, IDENTIFY THE
SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
LED INDICATORS: This smoke alarm is equipped with red and green LED indica-
tors. The green LED (when illuminated) indicates the presence of AC power.
The red LED has four modes of operation:
Standby Condition: The red LED will flash every 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 one flash per
second. The flashing LED and pulsating alarm will
continue until the air is cleared.
WHEN UNITS ARE INTERCONNECTED, only the red LED
of the alarm which senses the smoke or is being tested
(the originating unit) will flash. All other units in the
interconnect system will sound an alarm but their red
LED’s will NOT be flashing.
