HOW TO INSTALL THIS SMOKE ALARM
THE PARTS OF THIS SMOKE ALARM
FOLLOW THESE SIMPLE STEPS!
Tools you will need:
• Pencil • Drill with 3/16” (5 mm) drill bit
• Hammer • Standard Flathead screwdriver
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.
5. Tighten the screws (provided) into the screw anchors.
6. Activate the battery. With the battery
compartment open, install the battery
so the terminals on the battery match
the terminals on the Smoke Alarm.
Match “+” to “+” and “-” to “-.” Push
the battery in until it snaps in securely
and cannot be shaken loose.
If the battery is not snapped in completely, the unit cannot receive
battery power. The Smoke Alarm may beep briefly when you install
the battery—this is normal.
7. Position the base of the Smoke Alarm over the mounting bracket
and turn. The Alarm can be positioned over the bracket every 60°.
Turn the Smoke Alarm clockwise (right) until the unit is in place.
8. Test the Smoke Alarm. See “Weekly Testing.”

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 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.
Locking Pin
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
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 battery, always test the Smoke Alarm before
relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver between the
mounting bracket pin and the mounting
bracket.
2. Pry the Smoke Alarm
away from the
bracket by turning
both the screwdriver
and the Smoke Alarm
counterclockwise
(left) at the same
time.
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach one locking pin from mounting bracket.
2. Insert the locking pin into the lock located on the pivoting hinge of the
