Magnasphere HSS-L2D-008 Dual Contact with Tamper 820 Series

Protect critical entry points and simplify installation with the Magnasphere HSS-L2D-008 Dual Contact with Tamper. This magnetic contact combines UL634 Level 2 high-security performance with a dual closed-loop alarm configuration and an industry-leading tamper circuit to deliver dependable intrusion detection for security, surveillance and access monitoring systems. The surface-mount design requires no field adjustment, speeding deployment on doors, frames and enclosures while minimizing labor costs. Built to resist magnetic defeat and contact welding from power surges or tamper attempts, the HSS-L2D-008 maintains continuity under attack and reduces nuisance alarms—ideal for data centers, financial institutions, government facilities and other high-security installations. Optional embedded EOL resistor configurations streamline wiring and make the device plug-and-play with most alarm control panels. American-made Magnasphere switch technology ensures long service life and compatibility with existing monitoring equipment. Specify the HSS-L2D-008 for robust, low-maintenance perimeter protection or contact Magnasphere for custom resistor options to match your panel requirements.
