arrow. (see Figure 9) The tamper resist feature is now active and the battery
carrier can not be opened until the tamper resist feature is deactivated.
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 battery 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), disconnect the AC quick connector and
locate the small cut-out in the middle of the product label. Using a screwdriver, or
similar tool, move the slider away from the lock position (opposite the direction
indicated by the arrow). 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)
temporal alarm until the sensing chamber is cleared of smoke particles.
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 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 condi-
tion. 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.
This alarm has a low battery HUSH feature. If the alarm is sounding a low
battery 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.
