George Risk Industries 4532-36 Overhead Door Contact

Product Description

The George Risk Industries 4532-36 is an overhead door contact designed to monitor the open and closed position of overhead and commercial doors in security and access control systems. It ships with a 36-inch lead, providing enough wire length to route connections cleanly during installation without splicing. This type of magnetic contact is a core component in commercial intrusion detection, door monitoring, and building automation panels. Licensed security technicians and commercial electricians are the typical installers for this class of device.

The 4532-36 is suited for overhead door applications found in commercial and light industrial environments, including warehouse roll-up doors, loading dock doors, and similar large-panel door assemblies. The integrated 36-inch lead accommodates the wiring runs commonly encountered when mounting at the door header and routing back to a control panel or junction box. It is sold individually as a single unit.

Key Features

• Designed specifically for overhead and commercial door contact monitoring
• Includes a 36-inch pre-attached lead for direct panel wiring without field splicing
• Sold as a single unit for targeted replacement or new installation
• Compact form factor appropriate for header-mounted installation on large door assemblies

Compatibility

Designed as an OEM-style replacement or new-installation contact for overhead door security and monitoring systems in commercial and light industrial settings.

Installation Notes

Installation is typically performed by a licensed security technician or commercial electrician familiar with low-voltage wiring practices. Disconnect or disarm the alarm panel before making any wiring connections to avoid false alarms or panel faults. Route the 36-inch lead away from high-voltage conductors per NEC separation requirements. Verify door alignment and magnet gap tolerance before finalizing the mount to ensure reliable contact actuation.
