Flow switch, input and output module, spray pump, what linkage relationship
Spray pump and fire hydrant projection refers to the multi-line linkage module, not the input and output modules, is used to control the room directly to start the fire pump
Are input and output modules, because they need to feedback the signal and directly start the pump, and the sprinkler system is the same pressure switch, a group of straight line and a set of feedback lines, the feedback line is the alarm line, straight line is Directly to the pump control cabinet,
1, Flow switch and pressure switch need to take any module?
2 ,Fire system diagram, there is a flow between the water switch, and then flow control next to an input and output module, and then straight line straight line to the fire control cabinet, what the relationship between the three, how to wiring? Fire pump and spray pump are input and output modules and what mean? The
