Yes, each floor. The key word in the requirement for air venting is system. Definition of a sprinkler system basically defines a UMC.

As each floor has a separate control valve, is a means to vent trapped air required on each floor? Or is it only required at the highest level of the building? My thinking is that each floor has a separate fire sprinklers system. Any thoughts?
