1、帘板涂层脱落、锈蚀，帘板有明显的压坑、凹凸、穿透性孔洞。济南卷帘门厂提醒您，卷帘门是一个完整的消防产品，帘板如果出现问题会直接影响到卷帘门的耐火极限指标。

1. The coating on the curtain board falls off and rusts, and there are obvious indentations, bumps, and penetrating holes on the curtain board. Jinan Rolling Shutter Factory reminds you that rolling shutter doors are a complete fire protection product, and if there are problems with the curtain board, it will directly affect the fire resistance limit index of rolling shutter doors.

2、导轨变形等帘板卡住或降落不平滑。防火卷帘门一般都是沿着导轨移动的，如果导轨扭曲或者断裂，会导致卷帘门无法移动到指定的位置，从而达不到防火分隔的效果。

2. The guide rail is deformed, and the curtain board is stuck or not landing smoothly. Fireproof rolling shutter doors generally move along the guide rails. If the guide rails are twisted or broken, it will cause the rolling shutter door to be unable to move to the designated position, thus failing to achieve the effect of fire separation.

3、卷帘上，下限位失灵或限位线错接。这种情况经常会出现在中庭的防火卷帘上，由于中庭的防火卷帘有时候会装在上一层走道外，这就造成卷帘下无楼板与其闭合，漏出一条很大的缝隙，上下层的防火分隔就无法达到。

3. On the roller shutter, the lower limit fails or the limit wire is wrongly connected. This situation often occurs on the fireproof rolling shutters in the atrium. Due to the fact that the fireproof rolling shutters in the atrium are sometimes installed outside the upper walkway, there is no floor below the rolling shutters to close them, resulting in a large gap that cannot be reached for the fire separation between the upper and lower floors.

4、操作不动作、按钮触头烧坏，线路不通或者帘板只上不下或只下不上，相位错接，上下颠倒。部分防火卷帘门是设置在普通走道或者疏散走道上的，人员需要通过此处疏散，这就势必需要一个装置来手动控制卷帘门的动作，如果装置损坏会带来不必要的伤亡和损失。

4. Operation not working, button contacts burned out, circuit blocked, or curtain board only up and down or only down and not up, phase misaligned, upside down. Some fire-resistant roller shutter doors are installed on ordinary walkways or evacuation walkways, and personnel need to evacuate through this area. Therefore, a device is necessary to manually control the movement of the roller shutter door. If the device is damaged, it will cause unnecessary casualties and losses.

5、卷帘门上方或两侧未完全封堵或封堵材料耐火极限不符合要求。这个问题在消防验收过程中经常出现，一般施工单位或者卷帘门厂家都是将防火卷帘门安装在防火墙开口处并调试好，卷帘门电动机上方或者卷帘门两侧和导轨之间都未进行封堵，这就造成灼热的烟气通过分隔不到位的电动机上方、卷帘门两侧的缝隙和导轨之间，串到下一防火分区，从而导致大范围火灾蔓延。

5. The upper or both sides of the roller shutter door are not completely sealed or the sealing material's fire resistance limit does not meet the requirements. This problem often occurs during the fire inspection process. Generally, construction units or roller shutter manufacturers install and debug the fireproof roller shutter door at the opening of the firewall, but the motor above the roller shutter door or between the two sides of the roller shutter door and the guide rail is not sealed, resulting in scorching smoke passing through the gap between the motor that is not properly separated, the gap on both sides of the roller shutter door, and the guide rail, and running to the next fire compartment, This leads to the spread of large-scale fires.

6、业主安装不锈钢卷帘等未经检验机构检测的产品。部分单位由于对消防产品知识不了解，认为只要是钢铁的卷帘门都可以达到防火分隔的效果，殊不知防火卷帘门具有防火、防烟和隔热的功能，普通的卷帘门在火灾发生时，要么融化要么无法隔热防烟。

6. The owner installs products such as stainless steel roller blinds that have not been tested by national inspection agencies. Some units, due to their lack of knowledge of fire protection products, believe that as long as it is a steel rolling shutter door, it can achieve the effect of fire separation. However, they do not know that fire rolling shutter doors have the functions of fire prevention, smoke prevention, and insulation. Ordinary rolling shutter doors either melt or cannot withstand heat and smoke during a fire.

7、卷帘升降速度不符合要求。规范要求防火卷帘门的平均升降速度为3米/分钟，在消防验收过程中有时候会出现火灾情况已经确认，消防联动已经开始，可是卷帘门下降速度过于缓慢，整个过程持续将近6分钟或者更长，灼热的烟气早已串另一防火分区，防火卷帘门的防火分隔功能完全无法达到。

7. The lifting speed of the roller shutter does not meet the requirements. The national regulations require an average lifting speed of 3 meters per minute for fire resistant rolling shutter doors. During the fire inspection process, there may be situations where the fire situation has been confirmed and the fire linkage has started. However, the lowering speed of the rolling shutter door is too slow, and the entire process lasts for nearly 6 minutes or more. The hot smoke has already spread to another fire compartment, and the fire separation function of the fire resistant rolling shutter door is completely impossible to achieve.

8、业主自行改装卷帘门。现在许多高档场所一味追求富丽堂皇，嫌防火卷帘门过于难看，对防火卷帘门进行改装，比如在底板下加装装饰物，导致卷帘门无法下降到地面；又比如由于空间不够，将双轨双帘无机复合防火卷帘导轨之间的距离压缩，导致产品原先的耐火极限要求无法达到等，这些看起来都是小改动但都将卷帘门的防火分隔效果降低了。

8. The owner shall modify the rolling shutter door on their own. Nowadays, many high-end places blindly pursue grandeur and find fire-resistant rolling shutter doors too unattractive. They have modified fire-resistant rolling shutter doors, such as adding decorations under the base plate, which prevents them from falling to the ground; For example, due to insufficient space, the distance between the double track double curtain inorganic composite fireproof roller shutter guides is compressed, resulting in the original fire resistance limit requirements of the product not being met. These may seem like minor changes, but all of them have reduced the fire separation effect of the roller shutter door.

综上所述防火卷帘在安装调试过程中存在如此多问题，以引起安装调试单位重视，按照技术标准调试正常，真正使其起到防火分隔作用。更多相关内容就来我们网站http://www.jnhsjlm.com咨询吧！

In summary, there are so many problems in the installation and debugging process of the fireproof roller shutter that it needs to be taken seriously by the installation and debugging units. The normal debugging according to technical standards truly enables it to play a fire separation role. For more related content, come to our website http://www.jnhsjlm.com Consult!
