卷帘门安装之后出现一直报警等此类问题，一般有以下几个原因：

There are several reasons for such problems as continuous alarm after the installation of roller shutter door:

1、卷帘门电机出现故障，不能完全将卷帘门升起，需检查维修；

1. The motor of the rolling shutter door fails, and the rolling shutter door cannot be completely raised, so it needs to be checked and repaired;

2、卷帘门的卷扬系统出现故障，不能动作是卷帘门升起或者降落，随着故障的严重，可能提升力会随之下降，需要检查维修；

2. If the winding system of the rolling shutter door fails, the rolling shutter door will rise or fall. With the severity of the failure, the lifting force may decline, which needs to be checked and repaired;

3、卷帘门自身故障引起，卷帘门是有两侧轨道固定升降，如果卷帘门出现倾斜或者不平衡，会出现卡住，不能升降的现象，随着故障的严重，可能会越卡越低，需要对卷帘门进行调整。

3. The rolling shutter door is caused by its own failure. The rolling shutter door has fixed lifting tracks on both sides. If the rolling shutter door tilts or is unbalanced, it will get stuck and cannot be lifted. With the severity of the failure, it may get stuck and lower, so it needs to be adjusted.
