Recessed commercial door contact magnets install inside the door and frame for a clean, protected appearance, while surface-mount contacts attach directly to the door or frame for simpler installation. Track-mount contacts attach to overhead door or roller-door tracks and typically use armored leads and durable housings suited to the movement and impact those applications can involve.

Track-mount commercial door contact magnets are well suited for overhead doors and rolling doors because they attach to roller tracks and use durable housings with armored leads. Surface-mount contacts also support moving entry points such as gates and other commercial entrances, with mounting options that include adjustable brackets, screws, or adhesive tape.

Match the contact’s specified closed gap to the door and frame, then align the magnet with the contact so the gap remains within range when the door is closed and opens enough when it moves. Steel doors may require a recessed contact with a larger magnet for penetration, while overhead doors and roller tracks may call for track-mount or surface-mount contacts with wider gap ratings.

Match the commercial door contact magnet’s switch configuration, such as normally open Form A or closed-loop operation, to the alarm panel’s zone requirements, and use the contact’s wire leads or terminals with the panel’s specified gauge and end-of-line resistor arrangement. Confirm that the contact rating meets or exceeds the panel’s zone voltage and current, then verify the magnet’s gap and mounting style, such as recessed, surface, overhead-door track, or channel mounting, for the installation.
