If you want to lock the battery drawer, or lock the Smoke Alarm to the mounting bracket, please read the “Optional Locking Features” section before you begin installation.

FOLLOW THESE SIMPLE STEPS!

1.Hold base firmly and twist the mounting bracket counterclockwise to separate it from the base.

2.Hold the mounting bracket against the ceiling (or wall) so the vertical mounting slot is aligned in the 12 o’clock position and trace around the inside of the mounting slots (vertical and horizontal mounting).

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

4.Using a 3/16” (5 mm) drill bit, drill a hole through the center of the oval outlines you traced.

5.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.

6.Line the mounting bracket up

over the plastic screw anchors.

7. Screw the mounting bracket to the ceiling or wall through the mounting slots using the two screws provided.

8.Attach the Smoke Alarm to the mounting bracket. Line up the guides on the alarm’s base with the guides on the mounting bracket. When guides are lined up, turn the base clockwise (right) until it snaps into place.

NOTE: Once the Smoke Alarm is snapped onto the mounting bracket, you can rotate the Smoke Alarm to adjust the alignment.

9.Test the Smoke Alarm. See “Weekly Testing.”

OPTIONAL LOCKING FEATURES

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 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. Depending on which locking features you use, remove one or both pins from the mounting bracket using needle-nose pliers.

To permanently remove either locking pin, 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 install the batteries and test the Smoke Alarm.

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

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

2. After batteries are inserted, then push the locking pin through the hole near the battery door latch 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 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.)

3. To relock the battery compartment, close the battery door and reinsert locking pin in lock.

4. Reattach the Smoke Alarm to the mounting bracket.

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

TO LOCK THE MOUNTING BRACKET

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

2. Insert the locking pin through the hole on the back of the Smoke Alarm 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

1. Insert a flathead screwdriver into the rectangular cut-out on the mounting bracket nearest to the locking pin.

2. Pry the Smoke Alarm away from the bracket by pushing up on the screwdriver and turning the Smoke Alarm counterclockwise (left) at the same time.
