1. Fire-proof curtain doors are triggered by sensors to the control system. The control system sends instructions to the frequency converter according to the current position of the fast curtain doors, starts the driving motor to make the curtain rise rapidly, and the pedestrians automatically drop through the back curtain, closes the passage until the next opening signal opens again. As the name implies, the fast curtain doors The speed of rise and fall is very fast. It can't start and stop directly like steel coil gate. Frequency converter is usually needed to control the speed of motor. The faster the rise is, the better. When it is in place (about 20cm), a deceleration buffer stop process is needed to prevent impact on track, prevent clamping and reduce noise.
2. This is also a criterion for evaluating the performance of fast shutter doors. Fire shutter doors belong to the content of fire protection installation projects, and the installed fire shutter doors belong to building fire protection facilities, and can not be disassembled or changed at will. If we want to carry out relevant operations, we need to draw a plan layout map of the work site, mark the previous situation and the changed layout, and together with the company's qualifications, we will get the registration and filing of the fire department (small projects are generally large-scale management) window in the jurisdiction. Only after permission can we construct, we need to submit the application for acceptance and acceptance after construction.
