George Risk Industries 4532L Overhead Door Contact L-bracket

Product Description

The George Risk Industries Inc. 4532L is a mini-gap overhead door contact supplied with an L-bracket for secure mounting. This magnetic contact switch is designed to detect the open or closed position of an overhead door and transmit that status to an alarm or access control panel. The compact mini-gap form factor suits installations where standard-gap contacts will not fit. Electricians and security system technicians install this contact as part of commercial or residential door monitoring circuits. The included L-bracket simplifies alignment on overhead door tracks and frames without requiring custom fabrication.

The 4532L is suited for overhead door applications in commercial and industrial facilities where door position monitoring is required. Typical installations include loading dock doors, warehouse roll-up doors, and garage-style doors connected to intrusion detection or building automation systems. The unit ships individually and is intended for single-door installations.

Installation Notes

Installation is typically performed by a licensed electrician or certified security system technician. De-energize the alarm or access control panel circuit before wiring the contact. Secure the L-bracket to a fixed door frame surface and align the magnet to the switch within the manufacturer-specified gap tolerance to ensure reliable switching. Follow local electrical codes and the panel manufacturer's low-voltage wiring guidelines during installation.
