For fire main use a single O.S. & Y. valve shall be installed on the supply side of the approved dual check valve. The O.S. & Y. valve shall serve as the main control valve for the fire protection system. The assembly shall be listed in the "UL Fire Protection Equipment Directory" under "Backflow Special Check Valve Devices (BAEU)."

"Fire main" is that pipe, and its appurtenances, on private property between a source of water and the base of the riser for automatic fire sprinkler systems, open fire sprinkler systems, fixed water spray systems, fire standpipe systems and/or inlets to firefighting foam making systems. When connected to the public water system, the fire main begins at the supply side of the approved double check valve assembly or the approved dual check valve assembly. On NFPA 13D systems, the fire main begins at the point where the water supply line for the fire sprinkler system splits from the domestic water service.
