Proven Delayed Egress Innovation 

SDC pioneered the revolutionary delayed egress locking category to the industry in 1985 before patenting and 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. Since then, our delayed egress solutions have only gotten better with the ExitCheck®1511T series for double doors and the 1581S series mini delayed egress for smaller security needs and budgets. Every SDC delayed egress product and system solution is designed, engineered and built in America.
