Bus system usually consists of two to four wire circuits, a bus all detector and on the back, has its own independent address code, each detector controller according to the different address signal access each detector. Bus system thread, construction is convenient, strong scalability, can integrate other equipment easily through the input/output module, and simple expansion, most don't have to change the controller structure, so widely used. But bus system reliability is relatively low, a detector failure, may hurt behind all the nodes, and bad compatibility between different manufacturers products. Bus system is suitable for the large number detector, distribution, and the distance controller.
