ABB LDGRB-01 输入输出模块

火灾报警时，报警控制器通过输出模块启动需要联动的外控设备，如防排烟阀、送风阀、防火卷帘门、风机、警铃等，并可接受设备的动作回答。

输出模块连接在控制器的回路总线上，可以安装在所控设备的附近，也可安装在楼层端子模块箱内。采用电子写码，可以现场编码。输出模块的输出控制逻缉可以根据工程情况编程完成。当控制器接收到探测器的报警信号后，根据预先编入的程序，控制器通过总线将联动控制信号输送到输出模块，输出模块启动需要联动的消防设备；设备动作后会接受一个信号回答。

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（如海湾GST-LD-8301),相对应的还有双输入输出模块、多输入输出模块等等。

When a fire alarm occurs, the alarm controller activates the external control equipment that needs to be linked through the output module, such as smoke exhaust valves, air supply valves, fire resistant rolling shutter doors, fans, alarm bells, etc., and can accept the action response of the equipment.
The output module is connected to the loop bus of the controller and can be installed near the controlled equipment or inside the floor terminal module box. Electronic coding can be used for on-site coding. The output control logic of the output module can be programmed according to the engineering situation. After the controller receives the alarm signal from the detector, according to the pre programmed program, the controller transmits the linkage control signal to the output module through the bus, which starts the fire equipment that needs to be linked; After the device operates, it will receive a signal response.

The input and output module, also known as the control module, can output signals or provide a switching signal when there are control requirements to activate the controlled equipment. At the same time, it can receive feedback signals from the equipment to report to the host. It is an important component of the fire alarm linkage system. The input and output modules on the market can provide a pair of passive normally open/normally closed contacts to control the controlled equipment, Some manufacturers’ modules can be set to active output through parameter settings (such as Gulf GST-LD-8301), corresponding to dual input output modules, multiple input output modules, and so on.
