Magnasphere Corp MSS-89SL White Surface Contact 4 Open Loop

Product Description

The MAGNASPHERE CORP MSS-89SL WHITE is a surface-mount magnetic contact designed for open-loop security and sensing applications. This unit features a 4-open-loop configuration with 12 leads, giving installers multiple circuit options in a single compact housing. The white finish suits installations where the contact must blend with standard door and window trim. It is sold individually and is categorized as a special application contact, indicating use in environments or configurations beyond standard single-loop door or window sensing.

This contact is suited for residential and light commercial security, access control, and alarm systems where surface mounting is required. The 4-open-loop design allows wiring flexibility across multiple zones or redundant circuits. Installers working on perimeter protection, door and window monitoring, or specialized detection circuits will find the 12-lead configuration useful for more complex wiring layouts. The white housing is appropriate for interior doors, window frames, and trim in typical residential construction.

Installation Notes

Installation is typically performed by licensed security or low-voltage electricians in accordance with applicable NEC low-voltage wiring requirements. Power down or disarm the security panel before wiring the contact to avoid false alarms or circuit damage. Verify that each lead is correctly identified and terminated before securing the housing to the mounting surface. Follow the manufacturer wiring diagram for correct loop assignment across the 12 leads.
