Magnasphere Corp MSS-302C-BLACK Special Application Contact

Product Description

The MAGNASPHERE CORP MSS-302C-BLACK is a special application magnetic contact assembly consisting of one receiver unit paired with two switch elements configured in a dual closed-loop arrangement. This type of assembly is used in security, access control, and perimeter detection systems where reliable magnetic sensing is required. The dual closed-loop configuration provides redundant circuit paths, which supports tamper-detection or multi-zone monitoring within a single assembly. Installation is typically performed by licensed alarm installers, low-voltage technicians, or security system integrators working on commercial or residential detection systems.

This assembly is suited for applications where two independent monitored loops are needed from a single receiver location. Common installation scenarios include door and window contact points in access control panels, intrusion detection systems, and specialty monitoring installations that require closed-loop supervision. The black finish designation indicates the housing color, making it appropriate for installations where the contact must blend with dark-colored door or window frames.

Key Features

• Single receiver unit paired with two switch elements in one assembly
• Dual closed-loop configuration supports two independently monitored circuits
• Black housing finish for discreet installation on dark surfaces
• Sold individually as a single unit (each)
• Designed for special application contact use cases beyond standard single-loop sensors

Compatibility

Designed as an OEM-style replacement or new-installation component for special application magnetic contact systems requiring a dual closed-loop, single-receiver configuration.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed security system installer in accordance with applicable local codes and the manufacturer product manual. Power down or disarm the monitoring panel before wiring the contact assembly to avoid false alarms or circuit damage. Verify loop polarity and continuity with a multimeter after installation before restoring the panel to normal operation. Consult the product manual for mounting clearance and alignment requirements specific to this receiver and switch configuration.
