What batteries does the Glass Break Sensor use?

The Glass Break Sensor uses two CR123A batteries which last 3-5 years.  Your system is self-diagnosing and the Control Panel will alert you when any piece of equipment reports a low battery. The status will also display on the home screen of both the Frontpoint App and website. 

If a Glass Break Sensor reports the low battery, follow these steps to change the battery:

  • Open the Glass Break Sensor by unscrewing the Philips head screw on the side of the Sensor.
  • Replace the two CR123A batteries.  Make sure to insert the new batteries with the 2 positive ends facing towards each other.
  • Once the new batteries are placed the sensor, place the front cover back on the face of the sensor and tighten the screw back in.
