NFPA 14, 2019 edition and NFPA 14, 2016 6.1.1 Location of Dry Standpipes. Requires that Dry standpipes be monitored with supervisory air in accordance with NFPA 72. In the 2013 edition supervisory air was required where standpipe piping is concealed.
However, under a manual dry standpipe the piping is not under air pressure. Is the intent to require supervisory air for manual dry standpipes per the revision in the 2016 and 2019 editions?
