Magnasphere Corp MSS-201C-WHITE Recessed Magnetic Contact

Product Description

The MAGNASPHERE CORP MSS-201C-WHITE is a recessed magnetic contact designed for closed-loop security and access control wiring applications. The unit ships as a single piece and features a 3/4-inch form factor with 12-inch leads pre-attached for direct wire termination. Recessed contacts of this type are mounted flush into door frames or window frames, making them largely invisible once installed. The white finish integrates cleanly with painted wood, vinyl, or composite frame materials common in residential and light commercial construction.

This recessed contact is suited for installation in door and window frames where a surface-mount sensor is not acceptable or where aesthetics require a concealed solution. The closed-loop wiring configuration is the standard normally-closed circuit type used by most alarm control panels and access control systems. Installers working on perimeter zone wiring will find the 12-inch leads sufficient for most rough-in connections inside a door frame cavity or raceway.

Key Features

• 3/4-inch recessed housing fits standard bore drilled into door or window frame
• 12-inch pre-attached leads simplify termination without additional wire splicing at the sensor
• Closed-loop circuit configuration compatible with normally-closed alarm and access control panel inputs
• White finish blends with painted frame surfaces for a low-visibility installation
• Single-piece unit sold individually for flexible quantity ordering

Compatibility

Designed as an OEM-style recessed magnetic contact for use with standard normally-closed alarm panel and access control system inputs that accept a closed-loop wired zone.

Installation Notes

Installation is typically performed by a licensed alarm or low-voltage security technician in accordance with applicable local codes. A 3/4-inch spade bit or Forstner bit is required to bore the mounting hole to the correct diameter in the door frame or jamb. Ensure all power to the alarm or access control panel zone is isolated before connecting or disconnecting leads. Follow the panel manufacturer wiring guidelines for closed-loop zone termination to avoid nuisance faults.
