The fire shutter depends on the mechanical function of the fire separation function.

    Fire shutter is by mechanical action to complete its fire compartmentation function, and the mechanical facilities are bound to failure rate, if coupled with user management, not timely repair, such as reason, there may be a single failure when the fire broke out, and the mouth of the scale and is very big, so its safety reliability not high wall and fire door. Therefore, fire protection standard parts of the application rules of a clear, detailed constraints: used to close the openings on the floor, fire elevator room door, atrium corridors and other regional cohesion in and use a firewall to distinguish the fire zone and difficulties when available super fire shutter or general fire shutter differentiated water curtain protection, etc. These rules should be strictly adhered to in the planning of the project, and the scope of use should not be arbitrarily extended, and the fireproof shutter should not be used to "replace" the firewall or the partition wall.

    The fireproof shutter door adopts the control method of two steps down, and the alarm and action signal should be sent to the fire control room respectively, and emergency control measures should be taken in the special grade fire shutter. When the rapid fire shutter in the smoke detector announced before the signal, fire control room is on the active alarm plate should be announced the acousto-optic signal, active record time fire, fire site, fire prevention with zheng curtain door received signal, reduce to scheduled height, and appeared in fire control work station of indoor tray reflects the status of the rolling door in place. Rapid fire shutter in place after instruction by rolling shutter motor, gear drives the limiter screw rolling gear, collision block along the screw axial movement, affects in the micro switch on the corresponding position, through to the shutter, a signal of power supply. If the active alarm part light on the operating table is on, and the corresponding shutter door indicator light is not bright, it indicates that the electric control of the shutter door has some problems.

    At this point, it should be enabled immediately, with the shutter door control button located on the operating table to reduce to middle or bottom. If after the operation has not been able to make the shutter door lower azimuth indicator light, should send someone to the spot check the condition. It can be seen that the shutter door control of the fire control room should be reduced to the middle, bottom and ascending control buttons, and the indicator light with the middle and bottom position should be provided. Appearance check door rail, door fan has deformation, card resistance appearance, manual button is outstanding lock.
