On the basis of steel roller shutter, the transmission parts are transformed and equipped with fire-proof electrical appliances and other equipment to realize the fire-proof function: the fire-proof motor is controlled by the fire-proof electric control box, and the roller is driven by the speed change device to open and close the roller shutter door. In case of power failure, the manual handle on the fire-proof motor can also be used to realize manual operation. At the relative movement of machinery, the coupling is used to replace the sprocket drive, and the friction part in the track is inlaid with copper plate or nylon. It is suitable for factories and warehouses where combustible gases, volatile chemicals and other highly flammable substances are used or kept, which have or may have explosion fire hazards.

1、內部采用集成總線，數據傳輸可靠、迅速。
