SDC's 101-DE series delayed egress controllers incorporate all ExitCheck features into a 2-piece delayed egress system where the door is closed and secured by delayed egress locking hardware. The 101-DE series delayed egress controller sends power to the slave operating magnetic locks or exit devices to lock the door in a secured position. The integrated digital display on the 101-DE controllers provides an alternating verbal message, verbal countdown and alarm tone, plus a large digital countdown display and door release indicator to provide a clear warning for the safety of persons without prior knowledge of door operation, including the blind and hearing impaired. A built-in 3-function digital keypad provides reset, and timed or sustained bypass. Designed to delay egress through perimeter exit doors for 15 or 30 seconds, alert security and personnel to unauthorized egress, and are compatible with access controls and patient wandering systems. A choice of operation mode allows users to meet their local code compliance while meeting all national and regional building and fire life safety codes, including NFPA 101, Special Locking Arrangements. All SDC delayed egress locks release immediately in an emergency.
