I understand and agree Todd, before I shot my mouth of to the layout
tech I wanted to make sure I was headed in the right direction.
Thank you!

Ken, I think you would have to with the check valve. I would push back
a little in that by adding a normally open valve and a flow switch or
manifold would not change the physics of the system enough to warrant
the additional vents. If you had a 2 story building without zone
valves, you would only need one vent. However, if you add normally
open valves and flow switches, you would now need 2 (or 3?). From the
standpoint of physics, why?

Yes, Todd, on each floor, as they're using a Victaulic UMC manifold
which includes a check valve.

Is there a check valve on the floor control assembly?

Forumites,
I'm working on a multi-story building protected per NFPA 13. 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?
