In the fire engineering bus control module is installed in the horizontal level or installed in the fire control room?

In the fire project, the control module is there, basically distributed in different parts of the scene, according to the different needs of decentralized installation, or centrally installed in a module box, the module of different models can be realized in analog or digital input and output, of course, bus signals are included, the past has a four-bus system, and now a lot of products also have a two-bus system, out of the bus outside, will also be used in the line of power for the Some of the fire linkage equipment.

We mostly call control module, but have not called "bus control module", in the fire control room is the fire central console, the appearance, is a console, but the internal structure of the inside of the bus control devices and equipment (I do not know here can not be called a module).

I basically understand this.
