Magnasphere Corp MSS-105S Overhead Door Contact Rail Mount

Product Description

The MAGNASPHERE CORP MSS-105S is an overhead door contact designed for open-loop circuit configurations with a rail-mount installation profile. This unit falls within the special application contacts category, making it suited for security and access-control systems where reliable position sensing on overhead door assemblies is required. The rail-mount design allows for direct attachment to door rail hardware, providing a stable sensing platform in environments where overhead sectional or roll-up doors are present. Installation is typically carried out by security system technicians or electricians familiar with door position sensing applications.

The MSS-105S is intended for use on overhead door assemblies in both commercial and light industrial settings. Its open-loop circuit design makes it appropriate for alarm and access-control panels that monitor door position status. Typical install scenarios include warehouses, loading docks, commercial garages, and secured entry points where overhead door monitoring is a code or operational requirement. No specific compatible models or systems were stated in the available product data.

Key Features

• Open-loop circuit configuration for straightforward integration with alarm and access-control panels
• Rail-mount design for secure attachment directly to overhead door rail hardware
• Special application contact category, suited for demanding overhead door sensing environments

Installation Notes

Installation of the MSS-105S should be performed by a qualified security technician or licensed electrician. Disconnect and de-energize the door control circuit and any associated alarm panel zone before beginning work. Ensure the overhead door is secured in a stationary position before mounting the contact to the rail. Follow applicable local electrical codes and the access-control panel manufacturer's wiring guidelines when completing the circuit connection.
