Overview
Designed for dependable perimeter protection, the George Risk Industries 29B series surface-mount magnetic contact delivers reliable door and window monitoring for commercial security systems. The GRI 29B-W magnetic reed switch features an open-loop, normally-closed (N/C) contact and a 1-inch standard gap (5/8-inch on steel), providing consistent detection on steel or non-ferrous installations with minimal gap penalty. Its hermetically sealed reed and plated contacts resist sticking and freezing, lowering false alarms and maintenance overhead for integrators and facility managers.
Installation is straightforward: side-mounted screw terminals and included spacers, covers and screws speed mounting, while pre-wired and PA series cable options let you tailor connections to alarm panels and surveillance controllers. UL/ULC approvals and a lifetime warranty protect your investment and simplify compliance on access control and monitoring projects. Ideal for commercial doors, gates and asset protection, the GRI 29B-W combines durable construction with the flexibility installers need to keep security and surveillance systems reliable. Add the GRI 29B-W to your next access control or perimeter monitoring deployment for a robust, low-maintenance magnetic contact solution.
