SDC 1581S Delayed Egress Mini exit, 650lbs

Operation

Tone and LED annunciation includes two distinct tones indicating unauthorized egress in progress and unlocked. A tri-color LED mode status indicator indicating secure, unauthorized egress in progress.

When unauthorized egress is initiated, the Mini Exit Check® delays egress through the door for 15 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.

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.

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.
