Then there's the alternative means and methods clause which pretty much allows someone to decide gasoline in the pipes to keep them new and shiny is OK as long as the AHJ approves it. Now gasoline is an obvious no-no even when the AHJ is the dog catcher by day, crime fighter by night & AHJ by hobby, but what about an abort switch if Mr. PE says it's OK? Even a semi-savvy, over-worked AHJ might think water damage in this "server" room might be devastating. The double interlock pre-action system is obviously better than single (even though designed originally for freezer warehouses--essentially an extra slow dry pipe) and way superior to wet--that is if your goal is to not stop fires but rather stop water damage. Then the abort switch makes even more sense and allows the stockroom clerk, who is, after all, on the scene, to make decisions about fire protection during an emergency situation. And then there's the precedence of an abort switch on the wonder gas system. Isn't the presence of the wonder gas successfully used over and over to argue against the need for sprinklers in rooms containing computers? The AHJ described above, not savvy to UL 864 (after all, what does a fire alarm panel listing protocol have to do with fire sprinklers?), just might be happy to defer to the "educational" and "professional" credentials of Mr. PE.
