Signal wiring and Pump Remote Start button questions

Question asked by paperdimension on Apr 20, 2017

Hi all,

I have questions, I am working to install a 3 diesel pump engine based on NFPA 20 in US:

1. Is Modbus architecture acceptable to bring the pump running, controller status (manual/auto), and common trouble signal/status to a manned station (distance is ~1300 ft from pump room to the manned control room) or does it have to be hard-wired?


2. Does a remote start button required at the manned remote control room? Will it suffice just to have the pneumatic/electrical solenoid which open the deluge valves which in turn will turn on the pump?




Thank you in advance,
