What is the maximum pressure for standpipes and sprinklers when supplying the FDC?

The correct answer, which indicates a maximum pressure of 200 PSI, aligns with established guidelines for fire protection systems such as standpipes and sprinklers. This pressure threshold is important because it helps ensure the effective operation of the fire suppression systems without causing damage to the pipes, fittings, or the systems themselves.

Standpipes and sprinkler systems are designed to operate within specific pressure ranges to function optimally. Exceeding the maximum recommended pressure can lead to potential issues such as leaks, bursts, or the malfunction of components designed to withstand only a certain amount of pressure. By adhering to the 200 PSI limit for supplying the Fire Department Connection (FDC), firefighters can ensure that adequate water flow is available for firefighting operations while maintaining the integrity of the fire protection infrastructure.

Both national and local fire codes often specify this maximum limit to balance effective firefighting capabilities with the safety and reliability of the fire protection systems in place.
