Magnasphere HSS-L2C UL634 Level High Security Dual Alarm, Concealed Contact, Closed Loop with Closed Loop Tamper Circuit, 1" Diameter Recessed

Protect sensitive entrances and SCIF doors with purpose-built, professional-grade monitoring. The Magnasphere HSS-L2C UL634 Level High Security dual-alarm concealed magnetic contact delivers reliable perimeter security where failure is not an option. Designed for recessed 1" diameter installation or standard ANSI door cutouts, this closed-loop contact integrates a closed-loop tamper circuit and patented pry-detection to detect both door openings and removal attempts.

Unlike reed switches, Magnasphere switch technology resists permanent contact welding and provides long-term, low-maintenance performance. The HSS-L2C supports up to 30V DC operation and draws minimal power (250 mW/250 mA spec), making it compatible with a wide range of control panels and access systems. UL-634 Level 2 listing and TAA/RoHS2 compliance make this contact ideal for government, SCIF, and critical infrastructure installations.

Specify the HSS-L2C for enhanced surveillance and intrusion monitoring on high-security doors. Contact us to confirm panel compatibility or order this 3-year-warrantied security contact for your next perimeter protection project.
