Typically used on exit doors, when unauthorized egress is initiated when in the locked mode, the SDC Exit Check® delays egress through the door for 15 or 30 seconds. Meanwhile, the person exiting must wait while personnel or security respond. The door unlocks after 15 seconds have elapsed, permitting egress. A signal from the fire life safety system will release the lock for uninhibited egress in an emergency. 30 second delay available where approved.
Self Adjusting Door Movement Sensor
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.
Activation For Non-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 the SDC MSB550 Switch Bar or the SDC Sure Exit®, request-to-exit push bar. A power transfer device is required. Pushing on the requestto exit push bar immediately activates the delayed egress operation.
