Changing Your Motion Sensor's Battery

If you have received a Motion Sensor Low Battery notification on your Alarm Panel, you will need to replace the battery promptly to ensure the device continues to function properly. Information to order replacements can be found in our article, How to Order Replacement Batteries.

How to Replace Your Motion Sensor Battery

• Disarm your Alarm Panel before you begin this process

• Open the Motion Sensor by pressing in on the recessed tab at the bottom of the sensor and pulling the case toward you to remove the sensor from the base plate. (If there is a screw on the bottom of the sensor, please unscrew it.) 

• Pay close attention to the orientation of the (+) and (-) sides of the battery.

• Place the new CR123A battery in the sensor.

• Replace the sensor on the base plate

• To ensure that your Motion Sensor is functioning properly, press the tamper button on the side of the sensor to trigger a tamper. The alarm panel will report when a tamper has occurred. The tamper alert will clear on its own.
