Are sprinklers required to be controlled by valves which are physically located on the same floor level?
Are sprinklers in high ceilings OK to be controlled by valves on the upper level, or do they need to be controlled by a valve on the same level as the floor?
A project with a second, or even third-story high ceiling in a lobby would be one example of this scenario. Another example could be an entrance to an underground parking garage with an NFPA 13 system.
It makes sense for valves to control the sprinklers on the level the valve is on, just wondering about a specific code reference. I know about the exception for the top of stair shafts. Thank you everyone!
