INSTALLATION INSTRUCTIONS

Mark the desired location for the switch and magnet on the top edge of the door and door frame making sure your marks are in alignment.

Using a square, transfer the marks on to the top edge of the door and the opposing door frame.

Using a tape measure or graduations on the square, locate the center of the door edge and place an intersecting line with the first mark. Drill a 3/8” hole at the location where the marks intersect.

Repeat the above step to locate the hole position for the switch in the door frame. Drill a 3/8” hole in the door frame.

Apply adhesive or RTV to the end of the magnet and press the magnet into the hole you drilled in the door until flush with top edge of door.

Connect wire leads to screw terminal.

Insert wire leads into hole followed by the switch and press the switch into the hole until the head is flush with the door frame.

Test system for correct operation.
