Fire alarm in the high water tank in the flow switch how to connect the input and output module to start the fire pump
Whether the need to use an input module, when the traffic is over to the input module after the signal, and then the alarm host to the input and output modules to start the fire pump, if not the idea that is Zeyang?
And the pressure switch the same reason, need to connect input and output modules,
Any one behind the fire pump should have a control cabinet flow switch output relay analog signal electronic need to supply mechanical do not need dry contact signal can be Kiel China
because they need to feedback the signal and directly start the pump, a group of straight line and a set of feedback lines, the feedback line is the alarm line, straight line directly to the pump control cabine
