1.Remove the mounting bracket from the Smoke Alarm base. Hold the mounting bracket against the ceiling (or wall) and make a mark at the center of each of the mounting slots with a pencil.

2.Put the unit where it won’t get covered with dust when you drill the mounting holes.

3.Using a 3/16” (5 mm) drill bit, drill a hole through each pencil mark.

4.Insert the plastic screw anchors (in the plastic bag with screws) into the holes. Tap the screw anchors gently with a hammer, if necessary, until they are flush with the ceiling or wall.

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	Locking Pin
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 or utility knife • Standard Flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Using needle nose pliers or a utility knife, 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 unit.

1.Push and hold test button until the alarm sounds: 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 the Smoke Alarm still does not alarm, replace it 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 hole near the battery drawer on the back of the Smoke Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

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.Insert a flathead screwdriver under the
