If I have a floor area completely covered by sprinklers, and I have an opening for a couple of dormers. Sprinklers were added in the dormers. My question is; if the dormer sprinklers cover the same floor area as previously calculated sprinklers, do I need to add the dormer sprinklers to my calculations?? The dormer sprinklers are open the the floor below.
I have attached a picture of the area, highlighting the dormer sprinklers,
