OPTIONAL LOCKING FEA
TURES
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

The optional locking featur
es are designed to prevent unauthorized removal of the battery or alarm. It is not necessary to activate the locks in
single-family households wher
e unauthorized battery or alarm removal is not a concern.
These Smoke Alarms have two separate locking featur
es: 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
featur
es 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 pr
y the pin out of the lock.
