Nascom N505AU/ST048 Recessed Contact Flip Switch

Product Description

The NASCOM N505AU/ST048 is a recessed contact flip switch receiver designed for use with Neo 48-inch AC door and window framing systems. This unit functions as a magnetic contact sensor that signals an alarm or access control panel when a protected opening is breached. The recessed form factor keeps the switch concealed within the door or frame, maintaining a clean installation profile. It is sold as an individual unit and is installed by security technicians and alarm system integrators during new construction or retrofit security work.

This recessed contact is suited for residential and light commercial security applications where a low-profile, hidden sensor is required. The flip switch receiver design works in conjunction with a corresponding magnet to detect door or window position changes. It is intended for use within Neo 48-inch profile framing assemblies, making it relevant for door and window installations that use that specific frame system.
