George Risk Industries 20RS-T-BL Recessed Contact Terminal

Product Description

The George Risk Industries 20RS-T-BL is a black recessed contact with a press-fit terminal designed for use in door and window security and alarm circuits. With a 3/8-inch diameter and 1/2-inch length, this unit installs directly into a drilled hole in a door frame or window sash without requiring additional hardware. The press-fit design holds the contact securely in place during installation. It is sold individually and is commonly installed by alarm technicians, low-voltage electricians, and security system integrators.

This recessed contact is suited for residential and light commercial security and access-control installations. It is typically used in door frames, window frames, and cabinet panels where a flush, concealed sensor is required. The black finish allows the contact to blend with dark-colored frame materials, maintaining a clean installation appearance. Field technicians select this style of contact for retrofit and new-construction alarm wiring projects where a low-profile, reliable magnetic contact point is needed.

Compatibility

Designed as an OEM-style recessed contact for residential and commercial door and window alarm circuits requiring a 3/8-inch diameter press-fit terminal configuration.

Installation Notes

Installation is performed by licensed low-voltage technicians or alarm installers following applicable local codes and NFPA 731 guidelines. Power down the alarm panel or zone circuit before wiring the terminal. Drill the mounting hole to the correct diameter to ensure a secure press fit, and avoid oversizing the bore, which can cause the contact to seat loosely. Verify proper magnetic gap alignment with the corresponding magnet after installation.
