Methinks it is on him to show you where something is rather than your job to show him where it isn't. You could suggest your proof is the absence of any such requirement in the collected written codes of all time starting with Hammurabi and then challenge him to prove you wrong. Doesn't burden of proof rest with the plaintiff? In all the legal definitions I could find about this sort of dispute the term was "preponderance of evidence." Since you have four nationally recognized code models that are appropriate and do not mention this requirement I'd say it's now in his court to prove that his jurisdiction has a legally adopted law/code/ordinance/administrative ruling/etc., either statewide or local, and that this requirement exists in writing as legal text, enforceable within the definition of his warrant and authority. That said, I can't find anything after a perfunctory look at the IBC either. If I were to stretch it though, 903 requires water flow detection and also floor control valves. If I really wanted to be double anal and was of that type of mindset I might be able to convince myself that these two issues were related (which they're not). But in that case I could argue that if all the floor control valves were off and there was a fire in the stairwell I wouldn't have a signal going to the central station. Of course this would also apply to any number of other no flow scenarios I can construct that are based on highly unlikely conditions like all the water in the pipes being frozen, or interference from an EMP, or alarm signal eating cockroaches having a nest in the FAP, etc., and I haven't yet gotten to Osama bin Laden, Area 51, communist plots, or Mexicans crossing the border to steal our fire alarm signals.
