The SDC Security Door Controls Z7252GQ is an electric cylinder lock trim unit with integrated request-to-exit (REX) functionality, designed for use with Galaxy-series door hardware. It combines an electric cylinder lock mechanism with a REX sensor in a single trim assembly, allowing access control systems to monitor door position and release requests at a single point. Licensed locksmiths, access control technicians, and low-voltage security installers typically handle specification and installation of this hardware. The Z7252GQ is sold as a single unit and is suited for commercial door openings where integrated trim and exit-request monitoring are required.
This trim assembly is used in commercial access control installations where a Galaxy-series lockset is already specified or installed. It provides both locking and request-to-exit signaling from one trim unit, reducing the number of discrete devices required at the door. Typical applications include office entry points, server room access doors, and other controlled openings in light commercial environments where electric cylinder locking with egress monitoring is part of the access control design.
Designed as an OEM-style replacement or new-installation trim unit for electric cylinder lock applications using Galaxy-series door hardware with request-to-exit functionality.
Installation should be performed by a licensed locksmith or credentialed low-voltage access control technician familiar with electric hardware and applicable local codes. Power to the access control panel and door hardware circuit must be removed before beginning any wiring or mechanical work. Verify that the existing door prep and Galaxy-series hardware are compatible with this trim assembly prior to installation. Consult the manufacturer product manual for wiring diagrams and mounting specifications before proceeding.
