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

When you need uncompromising perimeter protection, the Magnasphere HSS-L2S magnetic contact delivers Level 2, tamper-resistant monitoring engineered for high-security sites. This UL 634 Level 2 magnetic contact is a surface-mount, closed-loop device designed for SCIFs, safes, vaults and other critical installations where defeat resistance and continuous supervision are mandatory. Built with an armored aluminum housing and Magnasphere’s non-reed switch technology, the HSS-L2S resists both internal and external magnetic defeat and includes an industry-leading removal tamper circuit for added assurance.

Installation is straightforward: the unit ships with wire-lead termination, a 4.3" form factor, and optional embedded EOL resistors to reduce field adjustments and simplify integration with existing control panels and access control systems. With a standard 0.25" gap specification and low power consumption, it supports reliable, continuous monitoring without heavy power draw. Ideal for security integrators and facilities managers, the HSS-L2S provides a robust, field-ready solution for intrusion detection and surveillance systems. Specify the Magnasphere HSS-L2S for your next high-security project—SCIFs, safes, vaults or any site requiring hardened contact protection.
