Troubleshooting False Alarms

It is important to IMMEDIATELY address any sensor trouble conditions as they occur. A low battery, loss of supervision, or abnormal sensor behavior can cause false alarms. 

Troubleshooting False Alarms 

  1. Check the sensitivity jumper on the back of the sensor, and decrease sensitivity if needed
  2. Verify that your sensor is installed in a climate-controlled environment, not outside or in a non-climate-controlled shed or garage.
  3. Verify that the sensor is not facing a window (the sun can heat up the window and may trigger your Motion Sensor)
  4. Make sure that large animals are not setting off the Motion Sensor (we suggest using Glass Break Sensors instead of Motion Sensors if you have large pets)
  5. Replace the battery (Battery Type: CR123A)

If you continue to encounter false alarms coming from that sensor, please reach out to our support team for further assistance.
