NOTE: Before activating the battery carrier tamper resist
feature, make sure a fresh battery is installed in the unit
and that the battery carrier is properly closed. If the bat-
tery carrier tamper resist feature is activated while the
battery carrier is open, the battery carrier will not close
and the unit will be inoperable during the loss of AC
power.
To deactivate the battery carrier tamper resist, in order
to change the smoke alarm battery, remove the unit
from the trim plate (see Smoke Alarm Tamper Resist Feature if activated), discon-
nect the AC quick connector and locate the small cut-out in the middle of the
product label. Using a screwdriver, or similar tool, slide the switch towards the
bottom of the product label. The battery carrier can now be opened and the
battery changed.
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once A.C. power is applied, fresh
batteries are 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.
SMART HUSH
TM
CONTROL: The “HUSH” feature has the capability of temporarily
desensitizing 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 HUSH feature cannot be activated unless the smoke alarm is sound-
ing in the originating alarm mode.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 sec-
onds every 8 seconds while in hush. This indicates that the alarm is in a tem-
porarily desensitized condition. The smoke alarm will automatically reset after
approximately 8 minutes 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.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEATURE AND
SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH FEA
TURE, 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 gr
een LED (when illuminated) indicates the presence of AC power.
