Nascom N122WGB/ST Recessed Magnetic Contact Ceiling

Product Description

The NASCOM N122WGB/ST is a recessed magnetic door and window contact designed for use in security and access control systems. This unit features a recessed mounting style with surface terminals, making it suitable for installation in ceilings or structural framing where a flush, low-profile fit is required. The contact set operates on a reed switch and magnet principle, triggering an open or closed circuit state when the door, window, or panel it monitors moves beyond the set gap. Security installers and low-voltage technicians are the primary trades that work with this component.

This contact is sized for standard 1/4-inch clearance applications and is suited for residential and light commercial security installations. The recessed form factor keeps hardware concealed within the door frame or ceiling surface, preserving a clean appearance while maintaining reliable detection. It is sold individually as a single unit.

• Recessed mounting style for flush, concealed installation

Compatibility

Installation Notes

Installation should be performed by a licensed low-voltage technician or qualified security systems installer in accordance with local codes and NEC Class 2 low-voltage wiring guidelines. De-energize the security panel and zone wiring before making any connections. Ensure the magnet and contact body are aligned within the manufacturer-specified gap distance to guarantee proper circuit switching. Avoid routing low-voltage signal wiring in the same conduit as line-voltage conductors.
