George Risk Industries 4612 Mini Curtain Door Switch

Product Description

The George Risk Industries 4612 is a mini curtain door switch designed for overhead door contact applications. This compact magnetic contact switch signals the open or closed position of a curtain-style overhead door to a connected security or access-control system. Electricians and low-voltage alarm technicians install this device as part of commercial or industrial perimeter-protection systems. Its small footprint makes it suitable for tight mounting locations along door frames and tracks where full-size contacts would not fit.

The 4612 is used in overhead door contact installations, typically in commercial warehouses, loading docks, and industrial facilities where curtain-style or roll-up doors require position monitoring. It fits into security alarm panels, access control systems, and building automation setups that require a discrete signal when a door is opened or closed. Installers mount the switch and magnet to the door frame and door surface, routing the low-voltage signal wire back to the control panel.

Key Features

• Sold as individual unit for flexible installation quantities

Compatibility

Designed as an OEM-style replacement or new-installation contact switch for overhead curtain door security and access control systems.

Installation Notes

Installation is performed by licensed electricians or low-voltage alarm technicians in accordance with applicable NEC requirements for signal and alarm circuits. De-energize the connected alarm or access control panel before wiring the switch leads. Mount the switch body to the stationary door frame and the actuating magnet to the moving door surface, following the manufacturer spacing tolerances shown on the product data sheet. Avoid routing signal wires in the same conduit as line-voltage conductors.
