The fireproof rolling shutter door is based on the steel rolling shutter, and the transmission parts are modified, equipped with fireproof electrical appliances and other equipment, so that the Henan fireproof door can achieve the fireproof function: the fireproof motor is controlled by the fireproof electric cabinet, and the roller is driven by the speed change device to make the rolling shutter door open and close. In case of power failure, the manual handle on the fireproof motor can also be used to achieve manual operation. Henan fire door is driven by coupling instead of chain wheel at the relative movement of machinery, and copper plate or nylon is inlaid at the friction in the track of Henan fire door. It is most suitable for factories and warehouses that use or store combustible gases, volatile chemicals of Henan fire doors and other materials with high flammability, where there is or may be an explosion fire hazard.

1. The integrated bus is used internally, and the data transmission is reliable and fast.

2. It has the functions of phase sequence automatic detection, correction and phase loss protection. The standby power of main power supply can be switched automatically (with standby power).

3. With rich reserved interfaces, it can be linked with the fire control center.

4. All electronic learning and memory limit, good, no matter the upper limit or lower limit positioning will never change.

5. It adopts advanced microcomputer processor technology, which is stable and reliable, without upper limit height and range

6. It has smoke and temperature sensing signal synchronization and step by step detection function

7. The setting of operation parameters is simple, convenient and accurate.

8. It has the function of manual priority escape. In case of three-phase power or main power failure, Henan fire door controller can automatically lower the roller shutter through quick release device to close the roller shutter.
