PG9914- Battery Replacement

When it is time to replace the battery in your motion detector, you will see an alert on your system panel, as well as a notification in the Alarm.com Mobile App.

The DSC PG9914 PIR Pet-Immune motion detector requires a 3-volt lithium CR123A battery, which can be purchased at your local hardware, mass retailer, or battery store.

Step-by-Step Instructions:

1. Locate the sensor with a low battery on either your system panel or in the Alarm.com Mobile App.

2. You can bypass the sensor on your panel or place you alarm on test mode from the app.

3. To open the cover, remove the locking screw from the bottom, then press the tab at the bottom of the sensor to remove the cover.

4. Remove and replace the 3-volt lithium CR123A battery.

5. Make sure the area where the batteries are stored is clean and there is no corrosion.

6. Put the cover back on starting with the opposite end from which it was opened. You should hear a snapping sound if it closes correctly.

7. Arm and disarm the system to clear the bypassed sensor or remove it from test mode.
