Alarm closing

in the event of fire through mechanical closing device 

Operating principles:

During conveying operation of the conveyor system the closing element is situated above the opening and is retained there by means of the hold-open device (magnetic clamp).
In the event of fire detection the closing element, whose sealing elements are adjusted to the profile of the conveyor system, moves, driven by mechanically stored energy in a quarter circular movement as close as possible towards the continuous conveyor system. The closing element seals the opening three-sided overlapping T90. Remaining openings are closed through the exposure to fire.
The conveyor system shutter is opened by means of motor drive. All functions can be operated by remote control via control of the hold-open device, the local manual push button on the CSS or by means of the conveyor system control. 


Basic equipment see „Description of Conveyor system shutters"
- Hold-open device for keeping the CSS open
- Sensor for realizing the open position.
