Fire Department Connection

A Fire Department Connection, or FDC, is an inlet and pipe system that allows a responding fire department to supplement the water supply of a fire sprinkler system in case of an emergency. The emergency responders can connect a hose line from their pumper truck to the FDC and pump additional water into the fire sprinkler system to ensure sufficient water and pressure to suppress the fire effectively and also act as a backup in the instance that:

The domestic water supply delivers an inadequate amount of water.

A valve is erroneously closed between the domestic water supply and the sprinkler system preventing water from reaching the system during a fire.

A change to the facility’s occupancy since the fire sprinkler was installed poses a more significant hazard than the original sprinkler system was designed to handle.

FDCs are required for all fire sprinkler systems and standpipe systems (the pipes which enable firefighters to connect and use their hoses within a structure) according to NFPA 13 and NFPA 14.

A Fire Department Connection (FDC) allows a responding fire department to supplement the water supply of a fire sprinkler system in case of an emergency.

During the fire event, firefighters will connect a hose line from their pumper truck to the FDC and pump additional water at high pressure into the fire sprinkler system to ensure sufficient water and pressure to suppress the fire.

When water pressure has been terminated, the ball drip valve will release all water from the FDC standpipe downstream of the check valve.
