BRK electronic CO5120B user manual Using the Optional Locking Features, Battery Compartment Lock

USING THE 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 CO alarms have two separate locking features: one locks the battery compartment, and the other locks the CO 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, molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending on which locking features you use.

TO LOCK THE BATTERY COMPARTMENT:

IMPORTANT!

Do not lock the battery compartment until you have activated the battery and tested the battery back-up.

1. Activate the battery back-up by removing the “Pull to Activate Battery Back-Up” tab. Push and hold the test button on the CO alarm’s cover until the alarm sounds: 4 beeps, pause, 4 beeps, pause.

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

2.Using needle- nose pliers or a

utility knife, detach one locking pin from the mounting bracket.
