Anyone who happens to know the system, I'd be interested in the proper designations for these.

Talkgroup 10864 - ID'ed as '1F - Emergency'.
Talkgroup 25040 - 'Plant', 'Lab', 'Security'. Seems to be a security channel at least primarily. Units affiliating with it do not seem to use any other talkgroups. Security (gate) calls lab for authorization to let delivery folks in, with things like caustics, FedEx deliveries.

SDUSD. When the emergency button on their radios is pressed the radio jumps to this TG.
