防火卷帘门主要用于大型(大卖场)、大型、大型材料市场、大型展馆、厂房、仓库等有消防要求的公共场所。防火卷帘门拥有好的耐火强度及较长的耐火时间！

Fireproof rolling shutter doors are mainly used in large supermarkets (hypermarkets), large shopping malls, large professional material markets, large exhibition halls, factories, warehouses and other public places with fire protection requirements. Fireproof rolling shutter door has good fire resistance strength and long fire resistance time!

由于防火卷帘是应用于防火分隔之用，要求其必须在火灾事故现场拥有较高的耐火强度以及较长的耐火时间。因此防火卷帘门的制作要求较高，即要求整个系统能经受一定时间的高温考验，而防火卷帘门的耐火时间长短则成为防火卷帘合格与否的主要指标。

As the fire rolling shutter is used for fire separation, it is required to have high fire resistance strength and long fire resistance time at the scene of fire accident. Therefore, the manufacturing requirements of the fireproof rolling shutter door are high, that is, the whole system is required to withstand the high temperature test for a certain time, and the fire resistance time of the fireproof rolling shutter door has become the main index of whether the fireproof rolling shutter is qualified or not.

在通常情况下，大型建筑根据消防法的规定配置了消防控制系统。当火灾发生时，安装在房顶的烟感传感器接到烟雾信号，同时向控制系统报警，消防控制系统通过识别后接通火警所在区域的防火卷帘门电源，使火防火卷帘门域的防火卷帘按一定的速度下行。

Under normal circumstances, large buildings are equipped with a central fire control system according to the provisions of the national fire protection law. When a fire occurs, the smoke sensor installed on the roof first receives the smoke signal and gives an alarm to the central control system. After identification, the central fire control system connects the power supply of the fireproof rolling shutter door in the fire alarm area to make the fireproof rolling shutter in the fire rolling shutter door area go down at a certain speed.

当卷帘下行到离地面约1.5米位置时，停止下行，以利于人员的疏散和撤离。防火卷帘门在中间停留一定时间后，再继续下行，直关闭,卷帘门产品配置说明，采用材料制作。防火卷帘门的下行速度和中间停留时间可在安装时进行调整。

When the roller shutter goes down to about 1.5m above the ground, stop going down to facilitate the evacuation and evacuation of personnel. After the fireproof rolling shutter door stays in the middle for a certain time, it will continue to go down until it is closed. The product configuration description of the rolling shutter door is made of high-quality materials. The downward speed and intermediate residence time of the fireproof rolling shutter door can be adjusted during installation.

在此过程中，防火卷帘的耐火强度不够的话，就不足以支撑起在预计的时间里保证防火分隔的具体状态，而这对于火灾现场中的人们来讲则是灾难性的。因此，用来判读耐火强度的耐火时间，就成为了防火卷帘质量检测的关键。

In this process, if the fire resistance strength of the fire shutter is not enough, it will not be enough to support the specific state of ensuring the fire separation in the expected time, which is disastrous for people at the fire scene. Therefore, the fire-resistant time used to judge the fire-resistant strength has become the key to the quality inspection of fire-resistant roller shutter.

防火卷帘门的降落方式有两种：一步降和两步降落。作为防火隔断时，采用一步降落的方式。一步降落的报警触发条件：某防火区内任意两个独立的探测器报警，或者一个探测器与一个手报按钮报警，启动卷帘门一步降到底，并将卷帘门到底的状态信号，反馈给消防主机。

There are two ways to land the fire shutter door: one-step landing and two-step landing. When it is used as a fireproof partition, the method of one-step landing shall be adopted. Trigger condition of one-step landing alarm: any two independent detectors in a fire zone give an alarm, or a detector and a manual alarm button give an alarm, start the rolling shutter door to the bottom in one step, and feed back the status signal of the rolling shutter door to the fire host.

车道出入口的卷帘，必须采用两步降落的方式。两步降落的报警触发条件：防火卷帘两侧0.5米～5米内须安装有两种类型的报警探测器——感烟探测器和感温探测器。感烟探测器报警，控制卷帘门半降（距离地面1.8米），感温探测器报警，控制卷帘门降到底部。卷帘门半降的状态信号、全降的状态信号，要反馈到消防主机。

The rolling shutter at the entrance and exit of the lane must adopt the method of two-step landing. Alarm triggering conditions for two-step landing: two types of alarm detectors - smoke detector and temperature detector must be installed within 0.5m ~ 5m on both sides of the fire shutter. The smoke detector gives an alarm, controls the rolling shutter door to half lower (1.8m from the ground), the temperature detector gives an alarm, and controls the rolling shutter door to lower to the bottom. The status signals of the rolling shutter door half down and full down shall be fed back to the fire host.
