What is a fire department connection (FDC)?

A fire department connection (FDC) serves specifically as a point where firefighters can connect their hoses to the building’s fire protection system to supplement the on-site water supply during a fire emergency. This connection allows additional water to be pumped into the sprinkler or standpipe system from fire engines, enhancing the effectiveness of fire suppression efforts.

FDCs are strategically located to ensure quick access by firefighters in emergency situations, providing them with the ability to draw water directly from hydrants or tankers. They are typically marked with signage for easy identification and may vary in configuration based on local codes and standards.

The other options do not accurately describe what an FDC is. For instance, while a valve for controlling the water source is essential for managing the flow within systems, it does not describe the connection feature that the FDC provides. Similarly, automatic sprinkler heads serve a different function in fire suppression and are not related to the direct hose connection mechanism of an FDC. An alert system for fire department notification is also unrelated, as it pertains to communication rather than physical water supply infrastructure.
