防火卷帘门具有哪些优势特点?

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、内部采用集成总线，数据传输可靠、迅速。

1. The integrated bus is adopted internally, and the data transmission is reliable and rapid.

2﹑具有相序自动检测，纠正及缺相保护功能。主电源备用电可自动切换功能(带备电)。

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

3、具有丰富的预留接口，可与消防控制联动。

3. It has rich reserved interfaces, which can be linked with fire control.

4、全电子学习记忆限位，更准确，无论上限还是下限定位永远不变。

4. Full electronic learning and memory limit, more accurate, no matter the upper limit or lower limit, the positioning will never change.

5﹑采用先进微电脑处理器技术，稳定可靠，没有上限高度范围限制.

5. Advanced microcomputer processor technology is adopted, which is stable and reliable without upper limit height range

6、具有烟﹑温感信号同步﹑分步检测功能.

6. It has the functions of smoke and temperature sensing signal synchronization and step-by-step detection

7﹑运行参数的设置，简单﹑方便﹑准确。

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

8、具有手动优先逃生功能。在三相电或主电有故障时，控制器可通过速放装置使卷帘自动下降从而起到关闭卷帘的功能。

8. With manual priority escape function. When the three-phase power or main power fails, the controller can automatically lower the rolling shutter through the quick release device, so as to close the rolling shutter.
