INSTALLATION INSTRUCTIONS • Mark location for the switch on the door frame. • Drill a hole for the switch using a 3/4” Hole Saw for steel doors or a Forstner bit for 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. • Place a mark on the top edge of the door aligned with the center of the switch. • Press the springs inward on the sides of magnet. • Insert the magnet in u-channel in the top of the door centered with the alignment mark. • Release the springs to secure the magnet and complete the installation.
