Which connection is used by firefighters to access the water supply?

• A. Test Connection
• B. Fire Department Connection
• C. Pressure Gauges
• D. Discharge Criteria

Answer: (B)

Fire Department Connection is the point firefighters use to access the water supply for the sprinkler system. This exterior inlet lets a fire department pumper connect hoses to the system to pump water into it or to boost the supply when the building’s own water source is insufficient. It’s typically a Siamese-type connection with two 2.5-inch inlets and backflow protection to prevent water from flowing back out. The other options serve different purposes: a test connection is used for hydraulic testing and flushing, pressure gauges monitor system pressure, and discharge criteria relates to how water is discharged—not a access point for firefighting water.
