First Alert SA720 user manual Optional Locking Features, To Lock The Battery Compartment

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 have installed the battery and tested the unit.

1.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.

2. Push and hold Test/Silence button until the alarm sounds: 3 beeps, pause, 3 beeps, pause.

The Escape Light® will turn on. LED flashes once every second.

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.

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

4. 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 compart- ment, 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 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
