What does the acronym FDC stand for in fire service terminology?

• A. Fire Department Connection
• B. Fire Distribution Center
• C. Fire Data Channel
• D. Fire Dispatch Console

Answer: (A)

The concept tested is recognizing a common fire service acronym and its practical use. FDC stands for Fire Department Connection. This is the external point on a building’s standpipe or sprinkler system where firefighters attach hoses to pump water into the system. It allows the fire department to supply or boost water to the interior piping when hydrants alone aren’t enough or when the building’s internal supply needs augmentation. You’ll often see it as a Siamese-type connection with multiple inlets to enable a quicker, larger-volume water flow. The other terms don’t describe this specific external connection used to feed the fire protection system.
