中继模块的作用
中继模块在消防联动控制系统中扮演着重要角色，其主要作用包括：12
增加系统的抗干扰能力。中继模块通过电气隔离总线信号的输入与输出，实现探测器总线信号的隔离传输，从而增强整个系统的抗干扰能力。
扩展总线通讯距离。在电磁干扰较强的区域或总线长度超过一定限制时，中继模块能够延长总线通讯距离，确保信号的稳定传输。
赋予非编码探测器地址码。在某些厂家型号中，中继模块用于接收非编码类火灾探测器的报警信号，并赋予这些设备一个地址码，使得它们可以接入火灾自动报警系统，并在控制器上显示探测器的具体位置。
提高系统的负载能力和可靠性。总线型中继模块通过信号整形、滤波稳压和信号放大过流保护电路等部分，增加联动总线的负载能力，从而提高消防联动控制系统的可靠性。
