Which component routes AFFF concentrate to sprinklers and hose reels?

• A. AFFF supply
• B. Station control
• C. AFFF service
• D. Hycheck

Answer: (C)

The component that routes AFFF concentrate to sprinklers and hose reels is the AFFF service. This part of the system is where the concentrate from the storage supply is drawn in, metered to the correct foam-water ratio, and then pushed into the foam piping network that feeds the sprinklers and hose reels. In other words, the service unit handles the actual foam generation and delivery to the discharge devices. The AFFF supply is just the source of concentrate, not the routing mechanism. Hycheck is a valve that prevents backflow in the concentrate line, guarding against siphoning but not directing concentrate to the discharge points. Station control is the control interface for starting and monitoring the system, not the component that routes concentrate.
