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 first mark. Mount the donut magnet using the #4X1/2 flathead 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 flush with the door frame
•Test switch for correct operation and make sure gap performance is acceptable.
