George Risk Industries 29PD-B Dpdt Switch Surface Contact

Product Description

The George Risk Industries 29PD-B is a double-pole double-throw (DPDT) reed switch with a 2-circuit frame, finished in brown, designed for use as a surface-mount contact in security and access control systems. Reed switches in this category are magnetically actuated, making them well suited for door, window, and gate monitoring applications where a reliable open or closed circuit signal is required. The 29PD-B is installed by alarm system technicians and low-voltage electricians working on residential or light commercial intrusion detection and access control projects.

This surface contact switch is intended for mounting directly to door or window frames without recessing into the substrate. Its brown finish is selected to blend with wood-tone frames and trim commonly found in residential installations. The DPDT configuration provides two independent switching circuits from a single actuating magnet, giving installers flexibility to wire normally open and normally closed loops simultaneously from one device.

Key Features

• Double-pole double-throw (DPDT) reed mechanism allows simultaneous normally open and normally closed circuit outputs
• 2-circuit frame design supports multiple zone or loop configurations from a single contact point
• Surface-mount installation requires no routing or recessing into door or window frames
• Brown finish integrates with wood-tone and painted residential door and window trim
• Sold individually (quantity per unit: 1) for precise project ordering

Compatibility

Designed as an OEM-style surface contact for residential and light commercial door and window alarm loop applications compatible with standard low-voltage security panel inputs.

Installation Notes

Installation is typically performed by licensed low-voltage technicians or alarm system installers. Before servicing any connected panel or control board, disable power to the security system to avoid false triggers or panel faults. Surface contacts should be aligned with the corresponding actuating magnet according to the manufacturer data sheet gap tolerances to ensure reliable actuation. Follow all applicable local codes and NEC low-voltage wiring requirements when routing and terminating conductors.
