The phrasing is to the effect "supply water to systems". If it's normally closed it can't be a supply and wouldn't need supervision. Similar to jockey pump valve, they don't feed the systems during a fire.
For example IFC 903.4 Sprinkler system supervision and alarms. All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and temperatures, critical air pressures and water-flow switches on all sprinkler systems shall be electrically supervised by a listed fire alarm control unit.

Is there a general requirement that all valves in a pump room be supervised? I am wondering about the valves in a flow meter loop that are normally closed.
