Magnasphere HSS-L2D UL634 Level High Security Dual Alarm, Surface Mount Contact Both Closed Loop with Tamper Circuit, Closed Loop

Deliver high-assurance perimeter monitoring where failure is not an option. The Magnasphere HSS-L2D magnetic contact is a UL 634 Level 2, surface-mount magnetic contact engineered for high-security applications such as SCIFs, safes, vaults and critical access-control points. Its dual-alarm closed-loop design includes an industry-leading removal tamper circuit to maintain continuous surveillance and reduce false trips. Built with armored cable options and available embedded EOL resistors, the HSS-L2D installs quickly with no adjustment required and integrates seamlessly with control panels that accept contact inputs. Unlike reed switches, Magnasphere’s switch technology resists both internal and external magnetic defeat for dependable, long-term performance. Rated for standard 30 V DC systems and backed by a 3-year limited warranty and TAA compliance, this magnetic contact supports rigorous security, monitoring and access control programs.
