Waterflow alarms on fire sprinkler floor control manifolds would not fulfill the requirement of 5.6.1, but neither is it intended that each individual standpipe be furnished with an alarm. At least one "master" flow alarm on every SYSTEM, except for manual dry.
The foregoing is my opinion only and does not necessarily represent the opinion or intent of the NFPA 14 Technical Committee on Standpipe and Hose Systems.

It also says Standpipe System - not standpipe, so is the intent as it sounds that one flow switch would satisfy the requirement for more that one individual standpipe that are interconnected?
