输入输出模块也称为控制模块，在有控制要求时可以输出信号，或者提供一个开关量信号，使被控设备动作，同时可以接收设备的反馈信号，以向主机报告，是火灾报警联动系统中重要的组成部分

市场上的输入输出模块都可以提供一对无源常开/常闭触点，用以控制被控设备，部分厂家的模块可以通过参数设定，设置成有源输出,相对应的还有双输入输出模块、多输入输出模块等等

Input and output module is also known as the control module, when there are control requirements can output signals, or provide a switching signal, so that the controlled device action, at the same time can receive the feedback signal of the device, to report to the host, is an important part of the fire alarm linkage system

Input and output modules on the market can provide a pair of passive normally open/normally closed contacts to control the controlled device, some manufacturers of the module can be set through parameter Settings, set to active output, the corresponding double input and output modules, multiple input and output modules and so on
