I'm reviewing a fire sprinkler system under 2019 NFPA 13D for a single family dwelling.
The living room basically has "reverse" ceiling pockets as the pockets are lower than the rest of the ceiling (pockets are at 10'-7", the ceiling is at 12'-1").
They have 2 sprinklers in each of the 3 lower sections of the ceiling but no sprinklers in the higher areas (except for a room to the side but in the same area).
It seems off to me to omit sprinklers in the higher area but can't figure out how to apply a code to it.
Would you apply the ceiling pocket rule if the higher area exceeds 100 cubic feet or is it fine as designed?
