Operating principles: 

During conveying operation the closing element is situated on or below the ceiling next to the opening and is retained there by means of the hold-open device (magnetic clamp).
In the event of a fire detection the closing element moves into the gap in front of the opening of the conveyor system, driven by mechanically stored energy and seals it all over, four-sided overlapping and without any residual openings.
In case of a motor-driven design all functions can be operated via control of the hold-open device, the local manual push button on the CSS or by means of the conveyor system control.
