You would still only sprinkler at the top of the stairs and the lowest landing if it’s not combustible. My concern would be if it required a standpipe.

But Todd, you think if a building has exterior, non-combustible stairs (such as say a fire exit), then it should be sprinklered? I haven't thought of it as that way, that is why I'm asking.

If the stairs are not heated can it be considered outside the building envelope? Which leads to a side observation. We provide sprinklers for balconies and below combustible overhangs that are over 4 feet wide. And won't that be outside the building envelope? So would not sprinklering outside the building envelope be a valid argument?

An NFPA 13, 2013 building has emergency stairs on the exterior of the building. Now it has been decided to enclose it, but will remain unheated. (1) Is it required to be sprinklered, if not enclosed? (2) Would the answer to (1) be different if enclosed?
