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

Protect critical assets with the Magnasphere HSS-L2D high-security magnetic contact — engineered for applications that demand uncompromising intrusion detection. This surface-mount magnetic contact delivers UL 634 Level 2 protection and a dual alarm closed-loop design with an industry-leading tamper circuit to ensure continuous, trustworthy signaling for security and surveillance systems. Built with armored cable options and Magnasphere’s non-reed switch technology, the HSS-L2D resists both external and internal magnetic defeat and maintains reliable operation across monitoring networks. Installation is straightforward: no adjustment required, standard 0.13" gap tolerance, and optional built-in EOL resistors simplify integration with control panels that accept contact inputs. Rated for commercial installations and compliant with TAA and RoHS 2 standards, this unit is ideal for SCIFs, safes, vaults and other high-security environments that require robust, wired intrusion detection. Specify custom armored cable lengths or order the HSS-L2D to harden your perimeter and improve real-time monitoring—contact sales or add to cart today.
