What is the purpose of a fire department connection (FDC) on a sprinkler system?

• A. To drain excess water from the system
• B. To provide additional water supply for firefighting
• C. To connect multiple sprinkler systems together
• D. To check system pressure and flow

Answer: (B)

The purpose of a fire department connection (FDC) on a sprinkler system is to provide additional water supply for firefighting efforts. When firefighters arrive at a scene with an active fire, they may need to supplement the water supply available through the building's system to effectively combat the fire. The FDC allows firefighters to connect their hoses and tap into a municipal water supply or a dedicated water tank, ensuring that there is enough water pressure and volume to support their firefighting operations. This connection is critical, especially in larger buildings or during significant fire events where the existing water supply may not be adequate. While draining excess water, connecting multiple sprinkler systems, and checking system pressure and flow are important functions in their own right, they do not represent the primary function of the FDC. The focus of the FDC's design is specifically to enhance the firefighting capabilities during an emergency situation by ensuring that a sufficient water supply is readily available.
