Using the Optional Locking Features

The optional locking features are designed to discourage 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 Smoke/CO Alarms have two separate locking features: one locks the battery compartment, and the other locks the Smoke/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 or utility knife

• Standard/Flathead screwdriver.

Battery Drawer Lock

Locking Pin

Mounting Bracket Lock

Both locking features use locking pins, molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending on which locking features you use.

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 Smoke/CO Alarm’s cover until the alarm sounds: 4 beeps, pause, 4 beeps, pause, 3 beeps, pause, 3 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 Smoke/CO Alarm immediately.

2. Using needle-nose pliers or a utility knife, 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 Smoke/CO Alarm.

TO UNLOCK THE BATTERY COMPARTMENT:

Once the Smoke/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 Smoke/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 Smoke/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 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 re-lock the battery compartment, save the locking pin.)

4. To re-lock 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 Smoke/CO Alarm, reattach the Smoke/CO Alarm to the mounting bracket, and restore the power.

When replacing the battery, always test the Smoke/CO Alarm before re-locking the battery compartment.

THE MOUNTING BRACKET LOCK

TO ACTIVATE THE BRACKET LOCK:

1.Using needle-nose pliers, detach one locking pin from the mounting bracket.

2.Insert the locking pin into the lock located on the base as shown in the diagram.

3.When you attach the Smoke/CO Alarm to the mounting bracket, the locking pin’s head will fit into a notch on the bracket.

TO DEACTIVATE THE BRACKET LOCK:

Always discharge the branch circuit before servicing an AC or AC/DC Smoke/CO Alarm. First, turn off the AC power at the circuit breaker or fuse box. Next, remove the battery from Smoke/CO Alarms with battery back-up. Finally, press and hold the test button.

1.Insert a flathead screwdriver between the mounting bracket pin and the mounting bracket.

2.Pry the Smoke/CO Alarm away from the bracket by turning both the screwdriver and the Smoke/CO Alarm counterclockwise (left) at the same time.
