What is the function of installing fire shutter doors?
The function of the fire shutter door, just like its name, is to prevent the spread of fire.The fire mode of the door is horizontal fire isolation fire in a certain space, and the door is separated by the curtain plate, the seat plate, the support, the roll, the box and other structures, so its installation position is generally separated by the firewall.Among them, fire shutter doors can be divided into steel fire shutter doors, composite fire shutter doors, inorganic fire shutter doors, etc., and according to the installation method, there are two kinds of fire shutter doors in the wall and fire shutter doors against the wall.If classified according to the opening direction, there are rolling shutter doors and side rolling shutter doors.Smoke detectors can detect fire signals faster than temperature detectors, and they can send out alarms faster, so. The first control signal is the alarm signal of the detector.Under normal circumstances, the fire roller curtain is automatically controlled by the following steps. After the fire shutter door receives the smoke detector alarm signal, the fire shutter door of the evacuation channel will drop 1.8 from the ground (building) surface to promote the escape of the building, and the other parts of the fire shutter door will drop to the bottom once; After a period of delay or temperature detector action. The roller blinds on the escape route descend to the bottom.2. Fire and rolling curtain action, fire rolling curtain alarm signal, half signal, bottom signal should be fed back to the fire control room3. When there is a fire, the fire alarm signal should be sent to the control room to control the water curtain solenoid valve to open automatically, so that the water curtain system can play a role.Although the fire shutter is equipped with dual power supply, if the power supply fails. In case of fire, the shutter door should not be powered on. The consequences are unimaginable.Therefore, the manual control device must be set on the roller curtain, that is, under the action of manual traction, through the pull rope. Pull the clutch of the shutter release and open the brake. The roller shutter closes by sliding through its own weight. In the design and installation, the release force should not be too dry, and the damping speed limiting mechanism should be provided to make the rolling shutter door drop at a uniform speed.It should be said that as long as it is a fireproof material that does not support combustion, it can pass the fire inspection. So from this point of view, there is no problem with plastic steel doors and Windows.Plastic steel doors and Windows are made of profiles + reinforced steel lining, which is a fireproof material.If the budget is more, you can consider the use of broken bridge aluminum alloy profiles and metal materials. Of course, they´re completely fireproof.
