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

Designed for high-security environments, the Magnasphere HSS-L2C is a recessed magnetic contact engineered to provide dependable door monitoring and tamper resistance for SCIFs, vaults, and controlled-access facilities. As a UL-634 Level 2 contact, this Magnasphere magnetic contact delivers elevated protection against covert defeat methods while integrating seamlessly into existing security and surveillance systems. Its patented pry-tamper circuit and concealed installation reduce false alarms and make bypass attempts immediately detectable. Installers benefit from flexible mounting—fits a 1" diameter hole or a standard ANSI cut-out—making it an efficient retrofit to older 2757/67 style contacts. The closed-loop contact supports wired control panels and operates on up to 30V DC with low power consumption, ensuring continuous monitoring without excessive load. Built from durable ABS and brass, the HSS-L2C resists permanent contact welding and is not a reed switch, offering long-term reliability in commercial security applications. Ideal for integrators, government facilities, and critical infrastructure projects—specify the Magnasphere HSS-L2C for robust tamper-resistant door security.
