SDC's Selectric 7800 Pro and Mod series solenoid controlled mortise locksets replace existing mechanical or electrifed mortise locksets for the access control of openings in commercial, industrial and institutional facilities where code compliance, dependable operation and resistance to physical abuse are required. These code compliant electric mortise locksets stay latched even when unlocked, maintaining fire door integrity and eliminate the need for exposed and vulnerable electric strikes and magnetic locks or request-to-exit devices. 7800 Pro series models incorporate a grade 1 heavy duty mortise lockset and vandal resistant clutch – proprietary to all SDC locksets. They replace most brands of mechanical locksets making them fully compatible with new and retrofit applications and provide field selectability of all operational attributes. All SDC mortise locks feature a mortise cylinder to manually retract the latch (Key cylinders sold separately).
