How do we use fire shutter doors?

    Everyone knows the fire shutter door or a good ban on fire, so how does it develop fire protection when the fire breaks out? Here are five things to know:

    1.. When fire occurs, smoke sensors installed in the roof (smoke) first received smoke signals, report to the central control bits and pieces at the same time, fire chirm central control through a process to identify the fire shutter on fire areas after the power and make the fire shutter press surrounding the fire may not speed up. When the curtain descends to about 1.5 meters from the sky, it stops descending to facilitate the cluster and evacuation of personnel. The fire resistant steel door is stranded in the middle and may not work, then continue up until the blockade.

    2. When a fire occurs, the fire shutter in the middle of the fire control system under the control of, according to the preset program to put down (down), so as to stop the fire from other scale lock function, taking valuable time for the implementation of fire extinguishing the fire.

    3. The descending rate of fire shutter door and the intermediate stop light will be developed at the time of installation.

    4. In some cases, the building equipment fire control of the central discipline and finely, fire shutter only depend on in the fire shutter fire control electrical box to complete the fire shutter operation criterion of fire prevention regulations. In this kind of environment, when the fire is produced, the smoke sensor takes over the flame and the flag signal is transmitted directly to the fire control electrical box of the fire shutter door. In the condition of power failure, only through the pull chain will fire shutter door down. Fireproof steel door equipment manual, only one way down, cannot be selected.

    Whether the fire shutter can effectively stop the spread of fire. There are many places where the fire shutter is used, and everyone should worry about a title, which is whether it is practical or not. Here's a look:

    The special grade fireproof roll curtain is the fire protection equipment for public fire protection zone and fire prevention interval. It is a mechanical and electrical interpretation of the compliance of fire-fighting products, in order to set up good fireproof rollers should always be deformed. In the process of application, special equipment should be used to make a living, and there must be common knowledge of electrician and machine root. In the process of monopolizing the application, the staff shall not be allowed to move out of the operation place, and should pay close attention to the condition of opening and closing and the situation of execution. In order to prevent the route switch failure, the shutter card dies, the motor hit the wall and other causes. Fire protection zone and fireproof partition of steel fire shutter usually do not make frequent use, once the area of fire, the curtain should be effectively put into use. It is necessary to carry out the passive control fire shutter with linkage control and peripheral control.
