SDC 1511SBDKVD Single Integrated ExitCheck Delayed Egress Lock, BOCA Buil-In Key Control, Aluminum Dull Brass

• The built-in door movement sensor may only be used with doors equipped with a latch assembly, such as a mechanical lockset or exit device. 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 self adjusting sensor helps prevent false triggering.
• 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 the SDC MSB550 Switch Bar or the SDC Sure Exit, request-to-exit push bar. A power transfer device is required. Pushing on the request to exit push bar immediately activates the delayed egress operation.
