当按下喇叭按钮时,电流会通过回路流到喇叭继电器的电磁线圈上,电磁线圈吸引继电器的动触点开关闭合,电流就会流到喇叭处。电流使喇叭内部的电磁铁工作,从而使振动膜振动而发出声音
如果没有电,应检查喇叭线束和喇叭继电器;
If there is no electricity, should check the horn and horn relay wiring harness;
每个传感器都有两个喇叭继电器和两个群继电器,并且每个警报主频都可以驱动任何一个通用继电器。
Each Annunciator can have up to two Horn relays and two Group relays and each alarm channel can be configured to drive any of these common relays.
由单片计算机控制的计数器自动产生通1秒停4秒的信号,使5路继电器输出带动电喇叭轮流通电。
By single chip computer control of counter automatically generate tong 1 second stop 4 seconds of signal, make no. 5 relay output drive electric horn turns electrify.
