The George Risk Industries 29A-B is a single-gap surface mount contact terminal designed for use in security, alarm, and access control wiring applications. This terminal provides a reliable connection point for low-voltage circuit wiring where a surface-mounted installation is required. The brown finish allows the terminal to blend with standard door and window trim in residential and light commercial settings. Security system installers and low-voltage technicians are the primary trades that work with this component.
The 29A-B is suited for surface mount installations on door frames, window casings, and similar flat substrates where recessed mounting is not practical. It is typically used as part of a perimeter detection circuit in residential or light commercial alarm systems. The brown color variant is appropriate for installations where aesthetics and color matching to wood trim or painted surfaces are a consideration.
Designed as an OEM-style surface mount contact terminal for use in residential and light commercial security and alarm wiring systems.
Installation should be performed by a licensed low-voltage technician or qualified security system installer. De-energize the alarm or access control circuit before making any wiring connections. Follow applicable local codes and NEC low-voltage wiring requirements when routing and terminating conductors. Avoid over-tightening terminal connections to prevent damage to wire insulation.
