I don't believe there is a requirement either way. But I personally think it best to locate the check valve as close to the FDC as possible (without getting into freezing problems). It's got to be easier on the system if it is ever charged by the fire department; and it gives a degree of supervision of the pipe between the check valve and the riser (in for form of dripping water if a leak were to occur).
