3. Installation Instructions
To activate the battery carrier tamper
resist feature, remove the unit from the
trim plate and locate the small cut-out in
the middle of the product label on the
back of the unit. With a small screwdriver,
or similar tool, slide the switch towards
the top of the label. (see Figure 8). 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 bat-
tery 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.
To deactivate the battery carrier tamper resist, in order to
change the smoke alarm battery, remove the unit from the
mounting plate, 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 carri-
er can now be opened and the battery changed.

4. Operation and Testing
OPERATION: The smoke alarm is operating once fresh batteries
are installed and testing is complete. When the smoke alarm ion
ization chamber senses products of combustion, the horn will
sound a loud (85db) temporal alarm until the sensing chamber is
cleared of smoke particles.
Hush® CONTROL: The Hush®feature has the capability of tem
porarily 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®button on the smoke alarm
cover. If the smoke is not too dense, the alarm will silence immedi
ately and the red LED will flash once every 10 seconds for approxi
mately 8 minutes. This indicates that the alarm is in a desensitized
condition. The smoke alarm will automatically reset after approxi
mately 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.
