Class III standpipe systems are equipped with which configuration?

Explanation:
Class III standpipes are designed to be a hybrid, offering both a large-diameter supply and a smaller hose for interior use. The configuration includes a single 2½-inch connection at the standpipe outlet for water from a fire department pumper, plus a single 1½-inch hose stored in the standpipe for occupant or interior firefighter use. This combination lets occupants begin fire attack with the 1½-inch hose while the engine supplies water through the 2½-inch connection. Other setups lack one of these essential features: a standpipe with only a 2½-inch outlet has no built-in 1½-inch hose for immediate use, while a standpipe with only a 1½-inch hose lacks the large-diameter connection for external water supply.
