If the code guys says that's permitted he should be fired. If you're responsible for the design of a system such as this you better know the codes and not just NFPA 13. Special hazard design will take you through a myriad of Codes and Standards and you need to know where to go to find answers.

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.
