INSTALLATION INSTRUCTIONS

• Mark location for the switch on the door frame and mark the location for the magnet on the top edge of the door.

• Make sure switch and magnet hole locations are aligned.

• 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 rst mark. Mount the donut magnet using the #4X1/2 athead screw provided.

• 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.

• Connect the switch leads to the alarm system. Caution! Hold wire leads, not the switch housing while cutting and

stripping to prevent damage to switch.

• Insert wire leads into hole followed by the switch and press the switch into the hole until the head is ush with the door

frame

• Test switch for correct operation and make sure gap performance is acceptable.
