Fire hydrant module of the 2 pump line received fire control cabinet, is not a 24V power supply, a pump line to start the pump?
I don't know very well about this module. As to what kind of cable you use, this is hard to say, but there are several necessary points to say here:1 fire hydrant button start signal: serial connected in the control cabinet labeled as fire hydrant switch terminals, cabinets built-in a BK transformer, power supply voltage is AC24V or AC48v.2 、 control center start signal: control center DC24V, power supply to control cabinet, a DC24V intermediate relay.Answer: 3, when the pump operation signal feedback to the control center, as an indication of the signal, using a set of general main contactor always passive signal, control the two pumps when the two pumps can be the normal open point in parallel.4, emergency start: some occasions need to set the emergency button, the general emergency start to consider when some electrical components can also damage when starting state, therefore, emergency start is generally directly to the power end to the emergency switch, switch wire connected to the coil of the contactor coil, the other end is connected with a power supply or the other 0 (voltage difference).This is the basic design requirements of fire control cabinet so you have to know that your fire module is fire hydrant, the start line group group is the control center start, the group is the answer signal, clear picture wiring OK.
You'd better be able to read the drawings. What you say is a 24V power supply and a startup pump is totally wrong. In fact, the two wires are connected in the control cabinet and labeled as the two point of the fire hydrant switch.
Fire hydrant starting water pump is through the hydrant button to close the signal, transmitted to the control cabinet as the starting pump switch signal. Generally AC24V (also AC48V), you can also understand the AC24V power supply in the control cabinet.
