ATS supply side but what about fire pump ATS

[hhsting]

Ok so I read in NEC 2014 somwhere in Article 230 I think?? that on supply side of service disconnect there is list of equipment allowed and ATS is not on the list.

So what about I have utiltiy transformer service conductors fed to straight fire pump ATS/controller and then to the fire pump? The fire pump ATS/controller would that be exception as fire pump equipment and be allowed on supply side?
