Sprinklers under underside of OPEN stair run??
(OP)
I was wondering what kind of protection is needed for the underside of the stairway (attached) if any? The stair run is 4'=6" wide.
Thanks
Thanks

Spaced to cover area under the escalator
Do you also have to provide opening protection ???

The first stair landing is at ~6'-10" while the top of the stair will hit the next level at 16'-0"
Here are some pictures i found on google:
