It is important to regularly test and maintain all of your sensors. A low battery or abnormal damage to the sensor can cause irregular activity.
- Verify that the sensor and magnet are securely mounted. If either piece has fallen off, the system will not function properly.
- Verify that the spacing between the sensor and magnet is no further than 1/2 of an inch when the door/window is closed.
- Verify that the door or window does not move excessively while it is closed.
- Verify that the sensor is located inside, away from large metal appliances, and in a climate-controlled environment.
- Replace the batteries (Two CR-2032 Batteries).
If the batteries have already been replaced and the issue persists, please contact our support for further assistance.
