I'll bet the site system on such a large building also serves hydrants. Mark - I don't think there's any requirement for interconnection. 13 says that a "system" requires an FDC, not a "building". I have worked with fire departments to interconnect multiple FDC's on special consideration sites, and have interconnected multiple interior systems to a single FDC, all in the name of making it easier/safer for the FD to step down and plug in with as little drama and confusion as possible. But I'm 99% sure the standard is mute regarding interconnection ...
