George Risk Industries 200-36 Overhead Door Contact 2.5 in Gap

Product Description

The George Risk Industries 200-36 is a floor-mounted overhead door contact designed for use in security and access control applications. It detects the open or closed position of an overhead door by monitoring a gap of 2.5 inches between the contact components. Installed at floor level, the unit provides a reliable signal to alarm panels and access control systems when door status changes. Licensed security installers and low-voltage technicians are the primary trade professionals who specify and install this type of contact in commercial and industrial settings.

The 200-36 is suited for overhead door installations where traditional surface-mount or door-frame mounting is not practical. Floor mounting positions the contact at the base of the door, making it well matched for roll-up, sectional, and similar overhead door configurations found in warehouses, loading docks, service bays, and light commercial facilities. The 2.5 inch gap specification accommodates the clearance typical of floor-level overhead door installations.

Key Features

• Floor-mount design for overhead door applications with limited frame mounting options
• 2.5 inch operating gap accommodates typical floor-level door clearance
• Sold individually, one contact per unit
• Compatible with standard alarm and access control panel wiring

Compatibility

Designed as an OEM-style replacement or new-installation contact for overhead door security and access control systems where a floor-mounted configuration and 2.5 inch gap rating are required.

Installation Notes

Installation is typically performed by a licensed low-voltage or security systems technician in accordance with local codes and NEC guidelines for low-voltage wiring. Disconnect power to the alarm or access control panel before making any wiring connections. Ensure the contact is securely fastened to the floor substrate at the correct position relative to the door travel path so the gap specification is maintained during door operation. Do not exceed the rated gap distance, as this may result in unreliable contact actuation.
