The SDC Z7550LRCHLG is a 24VDC solenoid-actuated electric strike designed for networked access control on fire-rated office, corridor, lobby, exit, and stairwell doors. This mortise-style strike eliminates the need for electric hinges or in-door wiring—all wiring stays contained in the door frame (strike jamb)—which preserves fire ratings and simplifies commissioning in buildings with strict code compliance requirements. Failsafe operation keeps the door latched even when de-energized, a critical safety feature for exit control and emergency egress scenarios.
The Z7550LRCHLG integrates with networked access control systems using 24VDC solenoid frame actuator control. It operates in both standard (1-3/4" to 2" frame face) and narrow (1-1/4" to 1-1/2" frame face) configurations, with left-hand reverse (LHR) handing in this SKU. The strike is Schlage trim-compatible and supports both locked-both-sides (Function 30) and locked-outside-only-failsafe (Function 50) configurations. Finish options include dull chrome (standard), bright chrome, dull/bright brass, dull/bright bronze, dark oil-rubbed bronze, and dull/bright stainless. Trim plates are available in Eclipse, Galaxy, Nova, and Schlage 07 equivalents. Any access control system capable of delivering 24VDC signals to a solenoid frame actuator can operate this strike.
The Z7550LRCHLG supports adjustable wide door gap compensation, accommodating frame flex and door sag common in commercial installations. Because wiring is contained entirely in the door frame rather than routed through the door leaf, frame prep is simpler and fire ratings on pre-hung doors remain intact. Confirm frame opening dimensions match your selected actuator option (standard or narrow) before ordering. Installation requires integration with your access control panel's 24VDC output and door sensor (or position switch) feedback if you need electronic verification of strike status. No electric hinge is required.
