NFPA 13 required sprinklers in concealed spaces where the space is in excess of 6" between the bottom of the joists and the ceiling. It also requires that sprinklers listed for use in concealed spaces under 36" deep be used. The Viking Coin, Tyco CC1 and 2 and the new Reliable concealed space sprinkler are listed for spaces from 12" to 36" deep. What are you supposed to do when the space is only 9" deep?
