Each area is connected with a fire alarm controller, and will the signal power line be divided into circuits?
To.The power line can be divided according to the situation and the system composition, that is, a host computer, then the signal line of this layer must be connected from the controller of the layer.
Each floor is followed by an area fire alarm controller. What you mean is the floor indicator. There are usually two kinds of layer display, the middle of the system displays the signal line separately, which is called system type, and the other is the layer connection circuit, which is called loop type from the detector signal line.If it is a fire alarm controller, that is a mainframe, then you have to signal this layer from the layer controller.The power line can be divided according to the situation and the system composition. There is no communication and no compatibility problems. Mainly considering the late line maintenance, convenient inspection, pressure drop and other issues can be.
The main consideration to the late line maintenance inspection is convenient, no compatibility problems, system alone significantly middle signal line, said should be the floor indicator (explicit), is from the signal line detector, called the system of each layer is connected with a regional fire alarm controller.
