Magnasphere HSS-L2C UL634 Level High Security Dual Alarm, Concealed Contact, Closed Loop, with Closed Loop Tamper Circuit, ANSI Cut-Out

For sensitive facilities that require the highest level of door monitoring, the Magnasphere HSS-L2C UL634 Level High Security Dual Alarm magnetic contact delivers certified, tamper-resistant protection for SCIFs, data centers and critical infrastructure. This Magnasphere magnetic contact uses proven non-reed switch technology in a recessed ANSI cut-out form factor to minimize exposure and reduce forced-entry risk. The closed-loop contact includes an integrated closed-loop tamper circuit and removal tamper, meeting UL-634 Level 2 requirements for dual alarm applications and continuous supervision. Rated for 30V DC operation with low power draw (250 mW) and a narrow standard gap (0.125"), the HSS-L2C provides precise, reliable door state reporting for alarm panels and security monitoring systems. US-made, TAA-compliant and RoHS2-certified, it installs quickly into standard ANSI door preparations to streamline deployment and reduce labor costs. Specify the HSS-L2C when you need hardened, auditable security for surveillance, access control and intrusion monitoring—order today for SCIF and mission-critical door protection.
