Optional Locking Features

The 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 Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the Smoke 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, which are molded into the mounting bracket. Using needle-nose pliers, remove one or both pins from the mounting bracket, depending on how many locking features you want to use.

To permanently remove either lock, insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you have installed the battery and tested the battery back-up.

1.Push and hold Test/Silence button until the alarm sounds:

3 beeps, pause, 3 beeps, pause. The Escape Light® will turn on. LED flashes once every second.

If the unit does not alarm during testing, DO NOT lock the battery compartment! Install a new battery and test again. If the Smoke Alarm still does not alarm, replace it immediately.

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

3.Push the locking pin through the hole near the battery drawer on the back of the Smoke Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

Once the Smoke 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 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.

Always discharge the branch circuit before servicing an AC or AC/DC Smoke Alarm. First, turn off the AC power at the circuit breaker or fuse box. Next, remove the battery from Smoke Alarms with battery back-up. Finally, press and hold the Test/Silence button for 5-10 seconds to discharge the branch circuit.

1.Remove the Smoke 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 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 locking pin in lock.

5.Reconnect the power connector to the back of the Smoke Alarm, reattach the Smoke Alarm to the mounting bracket, and restore the power.

When replacing the battery, always test the Smoke Alarm before relocking the battery compartment.

TO LOCK THE MOUNTING BRACKET

2. Insert the locking pin into the lock located opposite from the battery drawer as shown in the diagram.

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

TO UNLOCK THE MOUNTING BRACKET
