防火卷帘门如今应用的地方是越来越多了，所以我们应该多多去了解一些事项，以便以后能有所使用。在此说一个问题，防火卷帘门的有源和无源怎么进行区分？了解好这个问题，才能发挥出更好的卷帘门作用。

　　Fire shutter doors are now used in more and more places, so we should learn more about some matters, so that we can use them in the future. Here is a problem, how to distinguish the active and passive fire shutter doors? To understand this problem, we can play a better role of rolling shutter door.

　　消防模块大致可以分为输入模块，输出模块，输入输出模块，隔离模块，中继模块，切换模块，多线控制模块等等类型。开关量输入模块就是接收一个无源触点信号，通过该信号的输入接入到系统中，一般的输入模块可以用于接收水流指示器、压力开关、信号阀等等设备的报警、反馈信号。

　　Fire control module can be roughly divided into input module, output module, input and output module, isolation module, relay module, switching module, multi-line control module and so on. Switching input module is to receive a passive contact signal, through the input of the signal into the system, the general input module can be used to receive water flow indicator, pressure switch, signal valve and other equipment alarm, feedback signal.

　　综上所述无源所指的是模块。模块也分有源和无源。通常防火卷帘门控制箱也是无源的。常开指的是防火卷帘门没有收到消防控制的信号时，是处在常开的状态。防火卷帘门中无源常开就是不带电源的常开触点，也叫干触点。在防火卷帘门控制中常用在隔离和不同控制回路中传递和控制信号的接点。常开触点就是在线圈通电时处于闭合状态，在线圈断电时处于断开状态。

　　In summary, passivity refers to modules. Modules are also active and passive. Usually the fire shutter door control box is also passive. Normally open refers to that the fire shutter door is in normally open state when it does not receive the signal from the fire control center. Passive normally open fire shutter door is normally open contact without power supply, also called dry contact. In the fire shutter door control commonly used in isolation and different control loop transmission and control signal contact. Normally open contacts are closed when the coil is energized and disconnected when the coil is powered off.

　　济南卷帘门提示：有源就是有电，有发电方式，不仅供电，感应电，隔离都不好。电磁感应可以产生电、电弧等。因此，如果没有连接回路，只要触点在上述环境中容易产生感应电或回路电，就是有源触点。无源触点是在不同的控制回路中隔离传输和控制信号的触点。在不同的场合，防护等级和要求是不同的。当然，越高越好，这和使用环境有关。

　　Ji 'nan rolling shutter door tip: active is electricity, power generation, not only power supply, induction electricity, isolation is not good. Electromagnetic induction can produce electricity, electric arcs, etc. Therefore, if there is no connection loop, as long as the contact is prone to inductive or loop electricity in the above environment, it is active contact. Passive contacts are contacts that isolate transmission and control signals in different control loops. In different occasions, the level of protection and requirements are different. Of course, the higher the better, it depends on the environment.

　　防火卷帘门的有源和无源怎么进行区分？看完以上相信大家有所了解了。当然有源无源的使用是需要基于实际情况来作为的，不要随便乱使用，不然就会发生不好的影响。更多的内容就来网站www.jiahuawenti.cn咨询吧！

how to distinguish the active and passive fire shutter doors? after reading the above, i believe you have some understanding. of course, the use of active and passive needs to be based on the actual situation, do not randomly use, or it will have bad effects. for more information, please visit www.jiahuawenti.cn!
