The system has been in Sentinel for a while:

What isn't in RRDB nor in Sentinel is the talkgroups in use. Because of that you'll need ID Search turned on for the system (once you add it to a Favorites List) and then you'll be able to hear everything on the system until the talkgroups are identified.
Once you start to see the talkgroups in RRDB, Sentinel usually updates every Monday, and you'll have to update your favorites list once that happens. Since it looks like the primary dispatch channels for police and fire got added to RRDB today, they'll likely show with the Sentinel update on Monday.
Of course that doesn't mean you can't add them manually.
