Fireproof rolling shutter door is a type of fire prevention and insulation facility suitable for large openings in buildings, which plays a certain role in the design and installation technology of the product. What is the function and effect of the fireproof rolling shutter door? Let's take a look & nbsp; Fireproof rolling shutter door is based on steel rolling shutter, with the transmission part modified and equipped with fireproof electrical appliances to achieve fire prevention effect; The fireproof motor is controlled by the fireproof electrical control box, and the rolling shutter door is opened and closed by driving the scroll through the variable speed device. In case of power outage, the manual handle on the fireproof motor can also be used for manual operation. In mechanical relative motion, couplings are used instead of chain wheel transmission, and copper plates or nylon are embedded at the friction points inside the track. Suitable for use or storage of flammable gases, volatile chemicals, and other highly flammable materials in engineering and warehouses where there is or may be a fire hazard of explosion. 1. Internally, an integrated bus is used for reliable and fast data transmission. 2. It has the functions of automatic phase sequence detection, correction, and phase loss protection. The main power supply and backup power can automatically switch functions (with backup power). 3. It has rich reserved interfaces that can be linked with fire control. 4. The full electronic learning memory limit remains unchanged regardless of the upper or lower limit positioning. 5. Adopting microcomputer processor technology, stable and reliable, without upper limit height range restrictions. 6. It has the functions of synchronizing smoke and temperature sensing signals and step-by-step detection. 7. Setting operating parameters is simple, convenient, and accurate. 8. It has a manual limited escape function. In the event of a three-phase or main power failure, the controller can use a quick release device to automatically lower the roller blind and close it.
