1.窗帘板的涂层脱落并生锈。帘板有明显的压坑、凹凸和透孔。济南卷帘门是一个完整的消防产品。如果帘板有问题，将直接影响卷帘式卷帘门的耐火极限指标。

1. The coating of curtain board falls off and rusts. The curtain plate has obvious indentation, concave-convex and through-hole. Jinan rolling shutter door is a complete fire protection product. If there is a problem with the shutter, it will directly affect the fire endurance index of the roller shutter door.

2.导轨变形或落地窗帘卡不平稳。卷帘门通常沿着导轨移动。如果导轨扭曲或断裂，卷帘门无法移动到指定位置，无法达到分隔的效果。

2. The guide rail is deformed or the floor curtain card is unstable. The roller shutter usually moves along the guide rail. If the guide rail is twisted or broken, the roller shutter door cannot move to the specified position and cannot achieve the separation effect.

3.卷帘的上下限位置失效或限位线连接错误。这种情况经常发生在中庭的卷帘上。由于中庭的卷帘有时安装在上层走道的外面，导致卷帘下的楼层无法关闭，大的缝隙漏出来，无法实现上下楼层的分隔。

3. The upper and lower limit positions of the roller shutter are invalid or the limit line is connected incorrectly. This often happens on the rolling curtain of the atrium. Because the roll-up curtain of the atrium is sometimes installed outside the upper walkway, the floors under the roll-up curtain cannot be closed, large gaps leak out, and the separation between the upper and lower floors cannot be achieved.

4、操作不动作，按钮触点烧坏，线路受阻或帘板只上下、相位不对、上下颠倒。一些卷帘门安装在普通走道或疏散走道上，通过这些走道需要疏散人员，这将不可避免地需要一个装置来手动控制卷帘门的移动。如果设备损坏，将会带来不必要的伤亡和损失。

4. The operation does not work, the button contact is burnt, the line is blocked, or the curtain is only up and down, the phase is wrong, and the up and down are reversed. Some roller shutter doors are installed on common walkways or evacuation walkways, through which people need to evacuate, which will inevitably require a device to manually control the movement of roller shutter doors. If the equipment is damaged, it will cause unnecessary casualties and losses.
