How do fire pumps and jockey pumps interact during operation?

During normal operation, the jockey pump maintains the system pressure within the required range by compensating for small leaks or pressure drops. In the event of a fire, when the sprinkler system is activated and the pressure drops significantly, the fire pump automatically starts to provide additional water flow and pressure to the system, supplementing the efforts of the jockey pump.
