Where first-aid hose is direct-coupled to such standpipes an approved reducing coupling may be installed with not more than seventy-five (75) feet of one and one-half (1-1/2) inch hose connected thereto. The two and one-half (2-1/2) inch valve provided for Division use shall control the water supplied to the first-aid hose.
(b) In addition to the two and one-half (2-1/2) inch valved outlet, where this Fire Prevention Code requires first-aid hose stations to be located in public hallways, corridors or spaces separate from the standpipe locations, a one and one-half (1-1/2) inch branch shall be extended from the standpipe riser to the hose station and equipped with an approved shut-off valve sealed open by an easily broken seal at the point of connection with the standpipe riser. A sign indicating the purpose of the branch and of the shut-off valve shall be permanently secured at or to the shut-off valve.
