The optional locking features are designed to prevent unauthorized removal of
the battery or alarm. It is not necessary to activate the locks in single-family
households where unauthorized battery or alarm removal is not a concern.
These CO Alarms have two separate locking features: one locks the battery
compartment, and the other locks the CO Alarm to the mounting bracket.
You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard Flathead screwdriver.
Both locking features use locking pins, molded into the mounting bracket.
Using needle nose pliers remove one or both pins, depending on which locking
features you use.
USING THE LOCKING FEATURES
Locking Pin
THE BATTERY COMPARTMENT LOCK
TO LOCK THE BATTERY COMPARTMENT:
Do not lock the battery compartment until you have
activated the battery and tested the battery back-up.
1. Activate the battery back-up by removing the “Pull
to Activate Battery Back-Up” tab. Push and hold the
test button on the CO Alarm’s cover until you hear
an acknowledge chirp and the alarm sounds:
4 beeps, pause, 4 beeps, pause.
If the unit does not alarm during testing, DO
NOT lock the battery compartment! Install a new
battery and test again. If it still does not alarm,
replace the CO Alarm immediately.
2. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
3. Push the locking pin through the
black dot on the label on the back
of the CO Alarm.
TO UNLOCK THE
BATTERY COMPARTMENT:
Once the CO 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
CO 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 CO Alarm from the mounting bracket. If the unit is locked to
the bracket, see the section “To Deactivate the Locking Feature.”
2. Disconnect the power connector by gently prying it away from the back
of the 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 door and reinsert the locking pin in the
lock.
5. Reconnect the power connector to the back of the CO Alarm, reattach
the CO Alarm to the mounting bracket, and restore the power.
When replacing the battery, always test the CO Alarm before relocking the
battery compartment.
THE MOUNTING BRACKET LOCK
