What do I do if the Door and Window Sensor is showing as open on the Control Panel when it is actually closed?

This is typically caused by a mounting issue. Please check the following:

  • Ensure one piece is mounted on the door or window and the other piece is mounted on the frame
  • Ensure the arrows (or notches) on the transmitter and magnet are facing each other
  • The space between both the transmitter (larger piece) and magnet (smaller piece) should not exceed 3/4", or a thumbs width.
  • Check for any recess in the door/frame. Ensure both pieces are on the same plane

If the sensor is mounted correctly but the sensor is still showing opened, please contact Customer Support for additional troubleshooting assistance.
