This is out of NFPA 13 scope and NFPA 30 says nary a word about this situation, plus there does not seem to be an insurance company involved. The suppression methodology can vary from lots of water to any number of complicated exotica but the simplest with least maintenance cost is lots of water. The question is how much? Twenty minutes of any kind of EH2 or plus water has a big impact on the architecture. Allan Seidel St. Louis.
