What is a FDC connection?

The Fire Department Connection (FDC), also know as the Siamese Connection, is an important component found on most sprinkler and standpipe systems. When a sprinkler system activates, the fire department connects hose lines from a pumper truck to the fire department connection.

What does FDC stand for on a house?

FDC stands for Fire Department Connection. This is a connection on the exterior of a commercial building where a responding fire department can attach a fire hose and pump water into the building’s stand pipe system supplementing the water pressure to the buidling’s sprinkler system.

What pressure do you pump through a FDC?

150 psi
All pumpers will pump their capacity at 150 psi at the pump, so increase the throttle slowly until your discharge pressure is at 150 psi while being careful not to run away from your water supply. If your pumper is equipped with a multi stage pump, place the pump in the volume stage.

According to NFPA 13, the FDC should be installed on the fire sprinkler system’s side of its water supply check valve. When responding to a fire, firefighters hook the female end of their hose to a pumper truck and connect the male end of the hose to one of the FDC’s female swivel connections.

What pressure should I pump my standpipe?

The minimum pressure while flowing the required standpipe flow (500 GPM from the hydraulically most remote standpipe and 250 GPM from each additional standpipe, up to a maximum of 1000 GPM for a fully sprinklered building) shall be 100 psi at any valve outlet while flowing 250 GPM through each valve.
