Fire apparatus can be connected to what on the outside of the building to supplement the automatic sprinkler system?

• A. Hydrant
• B. Standpipe
• C. Fire Dept Connection (FDC)
• D. Inlet

Answer: (C)

The Fire Dept Connection (FDC) is the exterior point firefighters use to feed water into a building’s sprinkler or standpipe system. When a large fire overwhelms the building’s own water supply, hoses from the fire apparatus are connected to the FDC so water can be pumped directly into the system, boosting both flow and pressure where it’s needed most. This external connection is specifically designed for firefighting teams to augment the sprinkler network, making it the correct choice. Hydrants are separate street water sources and, while firefighters may draw from them, they don’t directly connect to the building’s sprinkler system through a dedicated exterior port. A standpipe refers to the building’s internal or exterior piping that firefighters use with attack lines, not the external interface used to feed the system. An inlet is too generic a term to describe this purpose.
