Jim, This was settled in MN by an administrative law judge back in the early 90's. Nothing has changed thus no RPZ or double checks required in MN. Doesn't matter what AWWA or plumbing inspectors have to say. There's even a staff opinion floating around the in the Dept. saying the same. Be careful you are not being played. I started this latest argument.
Now if it is a foam or anti-freeze system they have an issue. They really need to use some common sense. Anything a fire truck is going to put in is no worse than what is already in water. And they are having a hard time understanding fires are rare in sprinklered buildings and it's almost unheard of for a FD to use the FDC even when it's a fire in a sprinklered building. Remember most fires are out when the FD arrives. In 10 years in St. Paul and 16 years riding big RED trucks in other departments I only know of one case where the FDC was used on a sprinkler system.
