What does the fire department use the FDC for?

• A. To supplement the sprinkler system
• B. To drain the system
• C. To test the water quality
• D. To activate the alarm system

Answer: (A)

Fire department connections provide an external water source for the building’s sprinkler system. Firefighters attach hoses to the FDC to pump additional water into the system, boosting flow and pressure when the building’s own pumps or supply can’t meet the demand during a fire. This supplementation is the primary purpose, helping the sprinkler system operate effectively. The FDC isn’t used to drain the system, test water quality, or activate the alarm system—those tasks use other components like drains, test connections, or the detection/notification system.
