Overview

Ensure dependable perimeter protection with the George Risk Industries GRI 29A magnetic contact — engineered for commercial security and monitoring applications where reliability and easy installation matter. This surface-mount magnetic contact delivers closed-loop (supervised) N/O monitoring to keep alarm panels, access control and surveillance systems accurately informed. With a 1 inch standard gap (wide and extra-wide gap variants available), the 29A tolerates door/frame misalignment, reducing callbacks and installation time. Rated for 10W at 160VDC and 0.40A, the contact supports typical low-voltage security circuits, while side-mounted screw terminals speed up field wiring on metal doors and frames. The hermetically sealed reed and plated contacts resist sticking or freezing, improving performance in challenging environments. Backed by a lifetime warranty and US manufacturing, this gray, surface-mounted magnetic contact is UL/ULC approved for commercial installations. Ideal for retrofit or new-build projects—use the GRI 29A on entry doors, gates, cabinets and other access points to enhance intrusion detection and surveillance coverage. Add the GRI 29A to your security specification or contact us for installation guidance.
