This issue is generally due to a mounting issue with your Door or Window sensor, or that there is play in the door/window.
- Verify that the notches on both pieces are directly across from each other
- Check to ensure the sensors are no further apart than 3/4" (the closer the better)
- Check to ensure both sensors are flush with one another, no recess in the door or frame and on the same plane.
- Ensure there is no play (movement) in the door or window when it is closed.
If you’ve confirmed mounting is correct and the issue is not resolved, please contact Customer Support for additional troubleshooting.
