BTW, I probably should have included in my comments, the requirements for floor
control valve assemblies in NFPA 13, 2019 edition section 16.9.11, which might
be applicable to Jerry’s situation. Again, I may have missed the point of the
original question…. But I’m old so I have an excuse!
I am going through a very similar situation-2 story lobby with the floors zoned
separately. I couldn't find anything that says explicitly which floor to pick
this up from. One could certainly argue that it would be first floor based on
the room number following first floor numbering. I decided
Jerry,
NFPA 13 is clear that it is the designers responsibility to design the system
and chose the design method. It is the AHJs (reviewer’s) responsibility to
review the submitted design for acceptance to adopted codes and standards.
Unless the reviewer in your case is the owner’s
I’d ask why. Is the fire sprinkler system acting as detection system for a
smoke exhaust system?
Best.

I ask because this time it will require a 40'-0" drop and seismic assembly for
each sprinkler

I believe there was a change somewhere, or just good practice, but responders
like the ability to shut the system off from the floor they are standing on.
In other words, if you can see it, then the control valve should be on the
level you are standing.
I have been meaning to research this
We've had cases where the 2 story volume area is required to be protected from
the 1st floor system, but not the entire building just off of one system
because of that.
