Draft curtains for an exit access stair

[Sifu]

When draft curtains and closely spaced sprinklers are required by 1019.3 #4 for a 3 story building they would need to be placed at every floor opening. So in a 3 story, at the ceiling of floor 1 and floor 2...correct. Seems like a silly question but I have a DP who didn't provide them at all on the first submittal, and only wants to provide them at the ceiling of level 3 on the resubmittal. Or is it just a silly submittal?

I think I found the answer-at least as directly as it gets. 2022 NFPA 13 says "the floor openings involved". So the floor openings and not the ceiling.

Section 1019.3, Item 4, does state "...and the opening is protected by a draft curtain..."

The openings are not at the ceiling--they are between the 1st and 2nd stories and 2nd and 3rd stories.

That was my logic, but the code is very vague and silent about draft curtains and since the DP is apparently unclear how they should work I want to provide them some clear guidance.
