NFPA 13R

As I understand it, the 13R system can only be installed in Group R. I recently received a sprinkler plan for a school (Group E). The architect insists that a 13R is common practice on the west side of the state if the building is considered a light hazard. In Annex A of the NFPA it evaluates the reasoning for allowing the change from a full 13 system. Has anyone ever heard of a change, or interpretation which allows a 13R outside of Group R?
