TO LOCK THE BATTERY COMPARTMENT
This step should not be done until installation is
complete and AC power can be turned on as soon
as possible to conserve battery power. Activate the
battery and test the battery back-up before locking
the battery compartment.
1. Activate the battery back-up by
removing the “Pull to Activate
Battery Back-Up” tab.
2. Push and hold Test/Silence
button until the alarm sounds.
If the unit does not alarm during testing, install a
new battery and test again. If the alarm still does
not sound, replace it immediately.
3. Using needle-nose pliers
or a utility knife, detach one
locking pin from the mount-
ing bracket.
4. Push the locking pin through
the black dot on the label
on the back of the
Smoke/CO Alarm.
TO UNLOCK THE BATTERY COMPARTMENT
Once the Alarm is installed, you must disconnect it
from the AC power before unlocking the battery
compartment.
ELECTRICAL SHOCK HAZARD. Turn off the power
to the area where the Alarm is installed before
removing it from the mounting bracket. Failure
to turn off the power first may result in serious
electrical shock, injury or death.
1. Remove the Alarm from the mounting bracket. If
the unit is locked to the bracket, see the section
“To Unlock the Mounting Bracket.”
2. Disconnect the power connector by gently prying it
away from the back of the Smoke/CO Alarm.
3. Insert a flathead screwdriver
under the head of the locking
pin, and gently pry it out of
the battery compartment lock.
(If you plan to relock the
battery compartment, save
the locking pin.)
4. To relock the battery compartment, close the
battery drawer and reinsert locking pin in lock.
