MAGNET

INSTALLATION INSTRUCTIONS • Mark location for the switch on the door frame and mark the location for the magnet on the door. • Make sure switch and magnet hole locations are aligned.

• Drill holes for the switch and magnet using a 3/4” Hole Saw for steel doors or a Forstner bit for wood doors. • Press the magnet into the hole in the door until seated firmly against the head. Silicone may be used to secure the magnet in wood doors. • Connect the switch leads to the alarm circuit conductors. Hold the wire leads (not the switch housing) when cutting and stripping to prevent damage to the switch. • Feed the switch conductors into the hole and insert the switch housing pressing firmly until seated. Silicone may be used to secure the switch in wood doors. • Test switch for correct operation and make sure gap performance is acceptable.
