SDC pioneered the revolutionary delayed egress locking category to the industry in 1985 before launching ExitCheck® 1511S series in 1995 – the world’s first delayed egress lock to integrate a visual digital display, verbal countdown and alarm tone, alternating verbal message and door release indicator. There’s also a 1581S mini delayed egress for smaller budgets and a 1511T for double doors.
