SDC’s ExitCheck® delayed egress locks continue to be the premier delayed egress offering on the market. The patented design revolutionized delayed egress by incorporating 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. 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.

A variety of field selectable options allow for field selectable voice message and alarm tone, or alarm tone only; field selectable activation on door movement; exit device with switch kit; or pressure sense bars for non-latching doors; field selectable automatic or manual relock upon power up after emergency release or power loss; and a field selectable door prop alarm sounds when door is left open after the selected bypass time has elapsed.

The 1511S series incorporates all ExitCheck® features for single door applications with an integrated three position key switch for reset; manual power-up annd bypass settings for convenience.

Built-in activation for latching doors

The mechanical latch mechanism must be locked on the exterior and unlocked on the interior. From the inside, retracting the door latch and applying pressure causes limited door movement. The built-in activation trigger senses the door movement and initiates delayed egress operation. The adjustable sensor helps prevent false triggering.

External activation for latching doors

The external activation trigger input must be used with doors without latch assemblies, such as latchless glass and herculite doors. Activation may be triggered by SDC’s MSB550 or PSB560 series egress bars. A power transfer device is required. Pushing on a request-to exit egress bar immediately activates the delayed egress operation.

Keyless control

Although equipped with a standard built-in four function key switch for reset, manual power up, momentary bypass and sustained bypass functions, the SDC 920 wall mounted keypad provides the convenience of keyless operation for alarm reset, manual power-up, momentary bypass and sustained bypass functions.
