Magnasphere Corp MSS-106S-C36-L3.5 Overhead Door Contact

Product Description

The MAGNASPHERE CORP MSS-106S-C36-L3.5 is a closed-loop overhead door contact designed for special-application security and access-control installations. This rail-grey-finished magnetic contact monitors the open or closed status of overhead doors and transmits that status signal to a connected control panel or monitoring system. The closed-loop circuit configuration means the system registers an alarm condition when the circuit is interrupted, making it appropriate for high-security and life-safety monitoring applications. Licensed security and low-voltage installers are the primary trade installing this type of device.

This contact is suited for overhead door applications in commercial, industrial, and light-institutional settings where standard surface-mount contacts are not adequate for the door geometry or operating environment. The rail-grey finish is intended to blend with typical overhead door track and rail hardware, allowing for a low-profile installation. Special-application contacts like this unit are selected when door size, material, or movement pattern requires a purpose-built solution rather than a standard magnetic contact pair.

Key Features

• Closed-loop circuit design triggers alarm condition on circuit interruption
• Rail-grey finish integrates visually with overhead door track hardware
• Purpose-built for special-application overhead door monitoring
• Single-unit packaging suitable for individual door installations

Compatibility

Designed as a special-application closed-loop contact for overhead door installations where standard magnetic contacts are not suitable for the door type or mounting geometry.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician familiar with access-control and intrusion-detection wiring practices. De-energize the control panel circuit before connecting or disconnecting contact wiring. Follow applicable local codes and manufacturer wiring diagrams for loop supervision requirements. Verify door travel clearance before securing the contact to prevent mechanical damage during door operation.
