In general, large buildings are equipped with fire control system according to the provisions of the national fire protection law. When a fire occurs, the smoke sensor installed on the roof (hereinafter referred to as smoke sensor) first receives the smoke signal and gives an alarm to the control system. After identification, the fire control system connects the power supply of the fire shutter door in the fire area to make the fire shutter in the fire area go down at a certain speed. When the roller shutter goes down to about 1.8m above the ground, stop going down to facilitate personnel evacuation and evacuation. After the fireproof rolling shutter door stays in the middle for a certain time, it continues to go down until it is closed. The downward speed and intermediate residence time of the fireproof rolling shutter door can be adjusted during installation.
The manufacturing requirements of fireproof rolling shutter door are high, that is, the whole system is required to withstand the high temperature test of about 1100 ° for a certain time. The fire resistance time of fireproof rolling shutter door is the main index of fireproof rolling shutter door.
Steel fireproof rolling shutter is an important fire-fighting facility for fire compartment and fire partition in public places. It is a fire-fighting product with comprehensive mechanical and electrical performance. Therefore, the installed fire rolling shutter should always be in a normal state. During the use of steel fireproof roller shutter, special equipment shall be used and kept by special personnel, and have certain basic knowledge of electrician and machinery.
During operation and use, the operator shall not leave the operation site without authorization, and shall pay close attention to the opening and closing situation and implementation. No one is allowed to stand or walk under the roller shutter during opening and closing. To prevent travel switch failure, roller shutter jamming, motor obstruction and other accidents. The steel fireproof rolling shutter of fire compartment and fire partition is not frequently used at ordinary times. In case of fire in the area, the rolling shutter shall be put into use effectively. The automatic control fireproof roller shutter with linkage control and control center control must be carried out according to a set of control instruction program.
In case of any abnormality during use, emergency measures shall be taken immediately to cut off the input power supply and eliminate the fault. A regular maintenance system shall be established for the fireproof roller shutter, and the maintenance records of each roller shutter shall be made and filed. The roller shutter that does not open and close for a long time must be maintained once every six months, including eliminating dust, painting, adding lubricating oil to the sprocket and roller chain of the transmission part, etc. Check whether the electrical circuit and electrical equipment are damaged, whether they operate normally and whether they comply with various instructions. If they are damaged and do not meet the requirements, they shall be repaired immediately.
