George Risk Industries 29B-B Surface Contact Brown

Product Description

The George Risk Industries 29B-B is a surface mount magnetic contact designed for open-loop security and alarm circuit applications. This screw-terminal contact mounts directly to door and window frames, providing a reliable switching point for intrusion detection and access control systems. The brown finish allows the unit to blend with common door and window trim finishes. Installation is straightforward for alarm technicians and low-voltage electricians working with residential or light commercial security panels.

The 29B-B is used in surface-mount applications where recessed or flush installation is not practical or permitted. It is suited for wooden door frames, window sashes, and similar flat surfaces in residential and light commercial environments. The open-loop configuration means the circuit opens when the magnet separates from the contact, triggering the alarm panel. The screw terminal connection accommodates standard alarm wire without requiring specialty crimping tools.

Key Features

• Surface mount design for straightforward installation on doors and windows
• Screw terminal wiring connection for secure, tool-accessible wire termination
• Open-loop output configuration for standard alarm panel compatibility
• Brown finish for discreet blending with common trim and frame colors
• Single-unit packaging suitable for individual zone replacement or new installation

Compatibility

Designed as an OEM-style surface mount contact for use with standard open-loop residential and light commercial intrusion detection and access control alarm panels.

Installation Notes

Installation is typically performed by licensed alarm technicians or low-voltage electricians following local codes and NEC low-voltage wiring requirements. De-energize and disarm the alarm panel zone before making or breaking any wiring connections at the contact. Mount the contact body and magnet so the gap between them at rest does not exceed the manufacturer-specified actuation distance. Do not substitute the open-loop output wiring configuration with a closed-loop panel zone without verifying zone compatibility on the control panel.
