防火卷簾門如今應用的地方是越來越多了，所以我們應該多多去了解一些事項，以便以后能有所使用。在此說一個問題，防火卷簾門的有源和無源怎么進行區分？了解好這個問題，才能發揮出更好的卷簾門作用。

　　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.

　　消防模塊大致可以分為輸入模塊，輸出模塊，輸入輸出模塊，隔離模塊，中繼模塊，切換模塊，多線控制模塊等等類型。開關量輸入模塊就是接收一個無源觸點信號，通過該信號的輸入接入到系統中，一般的輸入模塊可以用于接收水流指示器、壓力開關、信號閥等等設備的報警、反饋信號。

　　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.

　　綜上所述無源所指的是模塊。模塊也分有源和無源。通常防火卷簾門控制箱也是無源的。常開指的是防火卷簾門沒有收到消防控制的信號時，是處在常開的狀態。防火卷簾門中無源常開就是不帶電源的常開觸點，也叫干觸點。在防火卷簾門控制中常用在隔離和不同控制回路中傳遞和控制信號的接點。常開觸點就是在線圈通電時處于閉合狀態，在線圈斷電時處于斷開狀態。

　　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.

　　濟南卷簾門提示：有源就是有電，有發電方式，不僅供電，感應電，隔離都不好。電磁感應可以產生電、電弧等。因此，如果沒有連接回路，只要觸點在上述環境中容易產生感應電或回路電，就是有源觸點。無源觸點是在不同的控制回路中隔離傳輸和控制信號的觸點。在不同的場合，防護等級和要求是不同的。當然，越高越好，這和使用環境有關。

　　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.

　　防火卷簾門的有源和無源怎么進行區分？看完以上相信大家有所了解了。當然有源無源的使用是需要基于實際情況來作為的，不要隨便亂使用，不然就會發生不好的影響。更多的內容就來網站m.santoncc.cn咨詢吧！

　　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 m.santoncc.cn!
