What does a foam concentrate supply system typically include?

• A. Tank, transfer pumps or gravity feed, and supply lines to the proportioning device.
• B. A single container of foam concentrate with no pumps.
• C. A network of chilled water lines.
• D. An external feed line only.

Answer: (A)

The essential idea is that a foam concentrate supply system must store the concentrate, have a way to move it, and deliver it to the device that mixes it with water. A typical setup includes a foam concentrate storage tank, a means to transfer the concentrate to the mixing point (either a transfer pump or a gravity-feed path), and the supply lines that carry the concentrate from the storage/transfer point to the proportioning device. From there, the foam concentrate is blended with water at the correct ratio for distribution through the sprinkler system. If you only had a single container with no means to move the concentrate, there would be no reliable way to feed the proportioning device. A network of chilled water lines isn’t related to foam concentrate supply, and an external feed line alone omits the storage and moving components needed to actually supply the system.
