| **** | Number of fire department connections: The water supply flow of each fire department connection should be calculated at 10 L/s to 15 L/s. The number of fire department connections for each type of water-based fire extinguishing system should be determined by calculation based on the system design flow; however, when the calculated number exceeds 3, it may be appropriately reduced depending on the reliability of the water supply. |
