George Risk Industries 4532 Overhead Door Mini Contact

Product Description

The George Risk Industries 4532 is a miniature overhead door contact designed for use in security and access control systems. This compact magnetic contact detects the open or closed state of an overhead door and sends a signal to a connected alarm or control panel. The 2-gap configuration allows for installation flexibility where the door and frame alignment may not be perfectly flush. Electricians and alarm system technicians install this contact as part of residential or commercial intrusion detection systems. Its small form factor makes it well-suited for installations where space around the door frame is limited.

The 4532 is intended for overhead door applications where a low-profile, surface-mounted contact is required. It fits common installation scenarios in garages, warehouses, and commercial facilities that rely on magnetic door contacts for perimeter security monitoring. The 2-gap design provides added tolerance during door operation, reducing false triggers caused by minor door flex or misalignment. Security contractors and licensed electricians typically specify this contact when upgrading or expanding existing alarm panel zones.

Installation Notes

Installation should be performed by a licensed electrician or qualified alarm system technician in accordance with applicable local electrical codes and NEC guidelines. Disable power to the alarm panel or zone circuit before wiring the contact. Mount the contact and magnet on opposing surfaces so they align properly when the door is in the closed position. Avoid routing low-voltage signal wiring alongside high-voltage conductors to prevent interference.
