Magnasphere Corp MSS-106S-C18-L2 Overhead Door Contact

Product Description

The MAGNASPHERE CORP MSS-106S-C18-L2 is a rail-mounted overhead door contact designed for use in security and access control systems. This magnetic contact mounts directly to the door rail, providing a reliable open or closed signal to the connected alarm or control panel. It is built for overhead door applications where standard surface-mount contacts are not practical. Alarm installation technicians and security system integrators are the primary installers of this device. The unit is sold individually and is suited for both new installations and replacement projects.

This contact is used in commercial and industrial overhead door security applications, including loading docks, warehouse roll-up doors, and garage-style access points. Rail-mount design makes it a fit for sectional overhead doors where a track or rail provides the mounting surface. It sends a state change signal to the alarm panel when the door opens or closes, making it a key component in perimeter protection systems.

Key Features

• Rail-mount design eliminates the need for surface or frame drilling on overhead door assemblies
• Magnetic reed switch operation provides reliable open or closed door status signaling
• Designed for overhead sectional door track installations
• Sold as a single unit for targeted replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-install rail-mounted magnetic contact for overhead door security and access control systems.

Installation Notes

Installation should be performed by a licensed alarm or low-voltage security technician in accordance with local codes and NEC Article 725 for low-voltage control wiring. Disable or disarm the security panel zone before removing an existing contact or wiring the new unit. Verify magnet-to-switch alignment and gap distance after mounting to ensure reliable state detection. Do not power the panel zone until wiring connections are fully terminated and insulated.
