I have a 3 story older building being renovated with sprinkler system being added. My question is can AHJ require a floor control valve to be added to each floor. Plans only show 1 floor control valve for the first floor. 1st floor being business, 2nd and 3rd floor being residential and attic space being sprinklered also. Concern of freeze and break in attic on older building and to be able to isolate a floor after a fire.
Thanks Chris Jones, Fire Marshal Urbana Fire Division
