Security Door Controls Z7252-G-Q Fail Secure Cylindrical Lock

Product Description

The SECURITY DOOR CONTROLS Z7252-G-Q is a fail-secure electrified cylindrical lock designed for access control applications in commercial and institutional facilities. Operating on 12 or 24 volts DC, this unit remains locked when power is removed, making it the correct choice for perimeter doors and security-critical openings where a locked state must be maintained during a power loss or system fault. The Galaxy lever trim and satin chrome (626) finish give it a clean, professional appearance suitable for office, healthcare, and education environments. It is specified and installed by licensed access control technicians and commercial door hardware professionals.

The Z7252-G-Q is intended for commercial hollow-metal and wood doors requiring electrified cylindrical lockset hardware. The Galaxy lever trim pairs with standard cylindrical lock preps, and the integrated request-to-exit (REX) function supports door monitoring and access control panel integration. This lock is suited for single-door openings where a fail-secure electric cylindrical lock with lever trim is required by the security design or code compliance plan.
