Glassbreak Sensor Not Responding

The warning ‘Sensor Not Responding’ for a Glassbreak Sensor can be caused by a couple of things, including a low battery or a weak connection between the device and the Base Station.

As a first step, we’d recommend ensuring that the battery is correctly installed. To do this:

1. Slide the sensor off its’ bracket by pushing it towards the wall and up

2. Remove the battery from the Glassbreak Sensor

3. Wait 15 seconds, then reinstall the battery again

4. Then, test the Glassbreak Sensor by placing your system into Test Mode using your Keypad.

1. Menu > Enter Master PIN > Test Mode

5. Press and release the button on the Glassbreak Sensor. The Base Station should announce “Glassbreak Sensor” and the timeline should show “Glassbreak Sensor Test” on the SimpliSafe Mobile App.

1. If you do not hear the Base Station respond, the battery within the Glassbreak Sensor may need to be replaced.

1. The Glassbreak Sensor takes a single CR-123A Lithium 3V battery. To replace the battery, slide the sensor up and off its’ bracket to expose the battery compartment. You can also follow the steps here.

If you have replaced the battery and are still encountering the ‘Sensor Not Responding’ error, it likely is the result of a weak connection to the Base Station. A weak connection to the Base Station can often be caused by something environmental, like brick walls or dense home construction.

To test this, temporarily move the Glassbreak Sensor closer to the Base Station and see if the error stops. If the sensor does work in a new location, it is likely the result of the environment near the prior location that is causing the conflict. You’ll have two options from here; Keep the sensor in its’ new location closer to the Base Station, or try to identify and clear the interference in the sensor's existing location. If you choose to keep the sensor in the location where it has encountered the error, you’ll want to look for environmental factors, such as dense building materials, or wireless devices that are nearby that could be interfering with the RF signal between the sensor and the Base Station. If you have any devices that output a wireless signal, we recommend trying to keep them at least 3-5 feet away from your sensor. That should help to clear up communication between the device and the Base Station.
