Recessed door contacts fit inside the door and frame for a cleaner appearance and can be suited to steel doors when paired with an appropriately sized magnet. Surface-mount door contacts attach to the door and frame with screws or adhesive, and some include spacers or screw terminals to simplify installation and wiring.

Choose wired door contacts for new construction, commercial installations, or locations with accessible cabling, including steel doors that call for a recessed contact. Choose wireless door contacts for retrofit projects or finished spaces where running cable would add installation work, and confirm that the contact matches the intrusion panel.

When connecting door contacts to a security system, confirm that the panel supports the contact’s connection method, such as wireless operation or hardwired terminals, and verify that the switch configuration and electrical rating match the zone input. For steel doors, select a recessed contact designed for steel construction, and check the mounting method, gap, and available space against the door and frame.

When comparing honeywell door contacts, check the switch type, such as Form A (SPST) or Form C (SPDT), and verify that the contact rating matches the security system, including 100 mA at 28 VDC for applicable surface-mount contacts. Also compare recessed or surface mounting, screw or adhesive installation, optional flush-mount spacers, screw terminals, wireless operation, and the required gap for the door and frame.
