By no means a definitive answer (or code-based approach), but we typically separate the scope at the system-side flange of the backflow preventer serving the fire sprinkler system. Plumbing contractors regularly install the backflows so it is a fairly easy break-point, although the valves on the backflow still need to be of indicating type and monitored by fire alarm.
