It is a fairly common occurrence to have partially sprinkled parking structures in my neighborhood (Atlanta). We see a lot of situations where a seven story parking deck might have a few levels underground that are sprinkled, with the rest of the deck not being sprinkled. In these situations, are the tops of the stairways required to be protected with sprinklers? Almost always, the only standpipes are dry manual so the only supply is off of the highest level dry system which would require routing pipe through multiple stair landings to get to the top.
As always, thoughts are appreciated!
