Magnasphere HSS-L2S UL634 Level High Security Single Alarm, Surface Mount Contact with Tamper Circuit, Closed Loop, Parallel Embedded EOL Resistors

Protect high-security openings with the Magnasphere HSS-L2S high-security magnetic contact. Engineered for SCIFs, safes, vaults and other critical facilities, this surface-mount contact delivers UL634 Level 2 tamper resistance and armored wiring options to defend against magnetic and physical defeat. The HSS-L2S is a closed-loop device with parallel embedded EOL resistors for consistent zone monitoring and easy compatibility with most control panels, reducing integration time and nuisance trips. Its built-in removal tamper circuit provides industry-leading detection that enhances surveillance and alarm monitoring without complicated adjustments. Designed as a drop-in replacement for existing BMS contacts, the HSS-L2S speeds retrofits and new installations while meeting TAA and RoHS requirements. Specify the Magnasphere HSS-L2S when you need reliable, audit-ready protection—ideal for high-security access points, evidence rooms, and critical infrastructure monitoring. Contact your security integrator or order today to add robust tamper detection to your security or surveillance system.
