You should probably confirm it with every one J.D. but it seems to me
if separation (protection, enclosure) is not required there would be
no reason to use sprinklers as an alernative for providing that
separation. It's been ten years since I last designed, calcd, and
listed a water curtain when it wasn't even required.
For history buffs-- water curtains were the first 'sprinkler
trade-off/equivalent'-- big multi-floor department stores with the
stairs in the middle. Instead of rated stair shafts they said closely
space open sprk (deluge) all around -- "walls of water".

Subject: RE: Vertical Opening [EXTERNAL]
Is this like an atrium?
What's the occupancy?
Any fire rating of floor/ceiling between levels?

Quoting JD Gamble <jgam...@lssofsheridan.com>:
I have a situation where we have 900sq.ft. vertical opening
communicating between two floors where a draft stop is not a viable
solution due to head room clearance. The design team isn't sure if or
how to protect it? Thoughts? Options?
It's a Light Hazard - Ord Hazard occ. The idea of "Barn Door" style
sliding doors is being proposed but my fear is these things being left
open in a fire situation.
I thought there was some direction in the 101 about communicating
spaces, but not sure. We do not recognize the 101 at the AHL level
but I think I could offer it as guidance .
