George Risk Industries 190-12-W-IND 3/4 Recessed Steel Door Contact

Monitor the open or closed position of a steel door from within a recessed 3/4 in mounting location. The George Risk Industries 190-12-W-IND door contact provides SPDT switching for security alarm, intrusion detection, and access-control status circuits. Its recessed construction keeps the sensing hardware contained within the door installation rather than projecting from the mounting surface. SPDT switching gives installers both normally open and normally closed contact arrangements from the same device. That flexibility matters when matching the contact to an alarm panel input, access-control controller, or supervised monitoring circuit with defined state requirements. Use the contact where a door-position signal is required to report whether a protected opening has moved from its secured position. This version is specified for steel-door use and uses a 3/4 in recessed format. It fits projects where the mounting method, door material, and contact type must match the existing security hardware design. The compact recessed approach is appropriate for commercial doors, controlled openings, and protected perimeter doors where visible surface hardware is undesirable. Verify the opening preparation and circuit configuration against the site’s installation requirements before fitting the contact.
