Magnasphere Corp MSS-201C-BROWN Recessed Magnetic Contact

Product Description

The MAGNASPHERE CORP MSS-201C-BROWN is a recessed magnetic contact designed for closed-loop security and access control wiring applications. Finished in brown to blend with common door and frame materials, this unit fits a standard 3/4-inch recessed bore and ships with 12-inch leads pre-attached for direct connection to alarm or access control panels. Recessed contacts are preferred in commercial and residential installations where a low-profile, tamper-resistant magnetic sensor is required. Installation is handled by security, electrical, or low-voltage technicians working within door frames, window frames, or similar entry points.

This contact is suited for residential and light commercial door or window monitoring installations. The closed-loop configuration means the circuit is normally closed and opens upon magnet separation, triggering the connected control panel. The brown finish makes it appropriate for wood-toned door frames and trim. The 12-inch lead length gives technicians adequate wire to route through the frame cavity and connect to terminal blocks without splicing.

Key Features

• 3/4-inch recessed form factor fits standard boring templates
• Closed-loop wiring configuration for normally-closed alarm circuits
• Brown finish for discreet installation in wood-toned frames
• 12-inch pre-attached leads reduce field splicing
• Single-unit packaging for replacement or new-installation use

Compatibility

Designed as an OEM-style replacement or new-installation recessed magnetic contact for standard closed-loop alarm and access control systems requiring a 3/4-inch recessed bore.

Installation Notes

Installation is typically performed by licensed low-voltage or alarm technicians in accordance with local electrical codes and NEC Article 725 for low-voltage wiring. Before servicing or replacing an existing contact, disarm the alarm system and disable power to the control panel zone being worked on. Drill the recessed bore to the correct 3/4-inch diameter and depth to ensure flush seating. Avoid sharp bends in the leads near the contact body, which can damage the internal wiring.
