Start the fire pump is generally divided into two kinds, the first way is to start in the bus system control mode, the fire hydrant starting through the action button in the linkage interface module will start the fire hydrant next to the signal sent to the requirements of the fire control room console switch contacts then output the fire hydrant startup. Second starting, is directly to the fire hydrant action button switch contact output to the fire hydrant pump starting box.
These two kinds of start-up mode can be used in practical design, before a connection, but in the bus system, hydrant linkage module programming to achieve the address encoding to monitor large fire hydrant. After the start of a simple and reliable, but also need to fire action signal back to the fire control room. The designer can select the size according to the actual engineering in the specific design, large scale and complex can be used before a start way, using a small scale after the start.
Since the start of the spray pump through the pipe nozzle is high temperature glass ball reserves under explosion, caused by network flow, and linkage alarm valve pressure switch, spray pump to achieve from the start. The water flow indicator alarm valve pressure switch or linkage module leads to the control room, fire control room can accurately reflect the action signal, at the same time the control room should be able to directly control the spray pump.
