Overview
Optimize perimeter security and access control with the George Risk Industries 29C surface-mount magnetic contact. Designed for reliable door and window monitoring in commercial and institutional environments, this magnetic contact simplifies installation while providing dependable alarm signaling. The 29C features an SPDT reed switch and a standard 1" gap (steel-adjusted rating available), supporting a 5W, 175VDC contact rating for compatibility with most alarm panels and access control inputs. Side-mounted screw terminals and optional pre-wired leads reduce labor time on site and enable clean, discreet wiring for surveillance and intrusion systems. Constructed with a hermetically sealed reed and plated contacts, the 29C resists sticking and corrosion for long-term reliability in active security deployments. Backed by UL/ULC approvals and a lifetime warranty, it’s a practical choice for installers specifying components for perimeter, door, and asset protection. Replace aging sensors or specify the 29C for new builds to streamline monitoring and lower long-term maintenance—contact sales for volume pricing or order now to secure your next project.
