Our jockey pump control panel in Chakan shows cut-in and cut-out settings. At what pressure should the jockey pump start and stop automatically?

In a typical system designed for 7.0 kg/cm² operating pressure: • Jockey Pump Cut-in: 6.2 kg/cm² (Starts when pressure drops due to minor leakage). • Jockey Pump Cut-out: 7.0 kg/cm² (Stops when line is fully pressurized). • Main Electric Pump Cut-in: 5.5 kg/cm² (Starts when flow exceeds jockey capacity, indicating active fire). The main pump must be stopped manually according to codes.
