How do I mount a Door and Window Sensor?

To mount the Door and Window Sensor, place one piece on the door (or window) itself and one piece on the frame. Ensure that the sensor is set up as follows.

  • The notches on the two pieces are aligned
  • The two pieces are less than 3/4" apart (less than a thumb’s width of each other)
  • The two pieces are flush on the same plane.
  • The door is within 100 ft. of the Control Panel.
