Magnasphere HS-L1.5 UL634 Level High Security Dual Alarm, Surface Mount Contact with 180" Armored Cable

Built for mission-critical environments, the Magnasphere HS-L1.5 high-security magnetic contact delivers dependable intrusion detection and tamper resistance where security matters most. This Magnasphere magnetic contact meets UL-634 Level high-security requirements and replaces older triple-balanced BMS devices to provide stronger protection for safes, vaults and data centers. With a 180" armored cable and aluminum housing, the HS-L1.5 stands up to physical abuse and attempted bypass, while its Magnasphere solid-state switching (not a reed) eliminates breakage or fuse failures that compromise monitoring.

Installers appreciate that the device requires no adjustment and typically needs no brackets for most out-swing doors, cutting installation time and cost. The contact supports dual-alarm configurations and closed-loop/N.O./open-loop wiring to integrate seamlessly with access control, alarm panels and surveillance systems. With low power draw (30V DC, 250 mW) and a standard 0.25" gap tolerance, it’s engineered for reliable, long-term performance.
