Having an interesting discussion with a senior field man.
He is concerned that some of the compressors pump to 125 +/-, and was asking about an AMD. I have searched, and also from a hands-on standpoint, do not believe one is required. It certainly is if we introduce a dry valve or deluge into the standpipe system, but then it gets a different name. NFPA 72 only mentions a 10 psi differential for supervisory circuits with air. Is an AMD required on this type standpipe? R/ Matt Matthew J.
