Optional Locking Features; To Lock/Unlock The Battery Compartment; To Lock/Unlock The Mounting Bracket - First Alert SA300 User Manual

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.
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 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

pin's head will fit into a notch on the bracket.
