Magnasphere MSS-320S Surface Mount Multi-Switch Contact with Armored Cable, Switches, Closed Loop

Built for dependable perimeter protection, the Magnasphere MSS-320S surface-mount magnetic contact delivers rugged, tamper‑resistant monitoring for doors and windows in security, surveillance and access control installations. This Magnasphere magnetic contact uses award-winning switch technology that won't break or fuse, providing consistent closed-loop (N.C.) signaling to alarm panels and monitoring systems. The armored cable and aluminum housing protect delicate wiring from damage and deliberate tampering while the 0.3" standard gap and 30V DC rating ensure predictable performance across common security platforms. With multiple independent contact outputs, a single MSS-320S can trigger several systems—ideal for sites that require simultaneous alarm, access logging and third-party monitoring. UL/ULC listing and TAA compliance make this unit a practical choice for commercial, institutional and government projects where reliability and approvals matter. Specify the MSS-320S for intrusion detection, door/window monitoring and integrated surveillance setups—contact us to add it to your next access control or alarm system deployment.
