Magnasphere Corp MSS-312C-GRAY Recessed Magnetic Contact

Product Description

The MAGNASPHERE CORP MSS-312C-GRAY is a recessed magnetic contact switch supplied as a single unit and configured with 2 closed loops. Designed for integration into security, access control, and building automation systems, this switch detects door or window position by monitoring magnetic field alignment between the sensor body and a mating actuator magnet. The recessed form factor allows flush mounting into door frames or casings, keeping the unit concealed during normal operation. It is typically installed by licensed electricians or low-voltage alarm technicians working on commercial or residential monitoring applications.

This contact switch is suited for recessed installation in wood, metal, or composite door frames and window assemblies where a low-profile sensor profile is required. The 2-loop closed configuration supports monitoring of both tamper and alarm circuits simultaneously, making it appropriate for supervised security zones. It is commonly specified in new construction and retrofit access control projects where aesthetics and concealment are priorities.

Key Features

• Recessed form factor for flush, concealed installation in door frames and window casings
• 2 closed loops support simultaneous alarm and tamper circuit monitoring
• Single-unit packaging for individual zone replacement or new installation
• Gray finish for a discreet appearance in standard interior trim applications

Compatibility

Designed as an OEM-style replacement or new-installation recessed magnetic contact switch suitable for supervised two-loop security and access control panel systems requiring a closed-loop configuration.

Installation Notes

Installation should be performed by a licensed electrician or certified low-voltage alarm technician in accordance with applicable NEC low-voltage wiring requirements. De-energize all circuits at the panel before making wiring connections. Ensure the actuator magnet and sensor body are aligned within the manufacturer-specified gap distance for reliable actuation. Avoid drilling into structural framing members without verifying clearance for concealed wiring runs.
