The MAGNASPHERE CORP HSS-L2D-800 is a conduit-mount dual alarm contact designed for special application security and alarm systems. This unit provides two closed-loop circuits in a single housing, allowing monitoring of two independent zones or providing redundant loop coverage within one device. It is intended for installation by licensed alarm technicians and electricians working on commercial or specialty security installations where conduit-mounted hardware is required by code or design.
The HSS-L2D-800 fits into conduit-mount configurations common in commercial security, access control, and alarm panel wiring environments. Its dual closed-loop design makes it well suited for applications where two separate supervised circuits must originate from the same physical mounting point. Installation typically occurs at door frames, panels, or junction points where rigid conduit runs terminate.
Designed as an OEM-style special application contact for conduit-mount alarm and security systems requiring dual closed-loop switching.
Installation should be performed by a licensed alarm technician or electrician familiar with low-voltage security wiring practices. De-energize the alarm panel and associated circuits before handling or connecting any contacts. Ensure conduit connections comply with applicable NEC requirements for the installation environment. Verify loop supervision settings at the panel after installation to confirm both circuits are recognized correctly.
