What role does a fire department connection (FDC) play in a standpipe system?

The fire department connection (FDC) is a crucial component of a standpipe system that allows firefighters to connect additional water supply lines, which is essential during a fire emergency. The FDC is typically located on the exterior of a building and serves to supplement the water supply available through the standpipe system. This is particularly important in situations where the existing system's capacity may not be sufficient to combat a large fire or when the building's internal water supply is compromised.

By connecting to the FDC, firefighters can bring in additional water from fire engines, enhancing the flow and pressure available for firefighting operations. This can be especially key in high-rise buildings or large facilities where the internal water supply may fall short. The FDC is strategically designed to allow for rapid and efficient connection, ensuring that firefighters can access the needed resources promptly when every second counts.

In essence, the FDC enhances the overall effectiveness of the standpipe system by providing an important means of augmenting water supply during firefighting efforts, ultimately improving occupant safety and property protection.
