Abstract
A system for remote-controlling a fire pump with a simple wiring construction is provided, being capable of conducting various kinds of control and display. The fire pump control system has an engine, a fire pump, an internal control apparatus, at least one external control apparatus located away from the fire pump including the internal control apparatus, and a twisted pair line for connecting the external control apparatus with the internal control apparatus. The internal and external control apparatuses form a network through the twisted pair line so as to control the fire pump through telecommunications from the external control apparatus. This network uses a p-CSMA system for communicating data, so that a high level of remote control can be carried out, with monitoring an operation state of the fire pump.
