MSS-310S-FIRE
Overview
Protect critical openings with the Magnasphere MSS-310S surface-mount multi-switch contact — a fire-rated, armored magnetic contact engineered for reliable, tamper-resistant monitoring in commercial security and life-safety systems. Unlike reed switches, the Magnasphere switch technology resists welding and outside defeat, giving integrators consistent closed-loop signaling for access control, alarm panels and building automation.
This MSS-310S-FIRE contact ships with armored cable and wire leads for secure, long-term wired connectivity and supports 30V DC input at just 250 mW power consumption, keeping panel loads minimal. The unit’s compact 2" length and 0.28" standard gap make it simple to install on metal frames or retrofit into existing surveillance and monitoring applications. UL-10C classification and RoHS compliance mean the contact meets demanding code and environmental expectations.
Choose the MSS-310S to consolidate multi-output signaling while maintaining high integrity monitoring for security, surveillance and fire systems. Contact our sales team or add to your system spec to upgrade door and perimeter protection today.
