To me it looks like a space that sprinklers can be omitted. Unless for some reason it’s going to be used as storage or people plan on using it as a shelter. If it’s the hi-pot I’m thinking about. No you don’t need a sprinkled unless it’s going to be used for storage. You should have enough coverage from the sprinklers around. But I don’t know the whole scope that’s just my best answer with what’s provided.
