Chris, In jails I've seen electrically operated zone valves with a 90 second time delay before the valves were opened, an "open now" override, and an abort to each valve but that required CCTV and a constantly manned station wherein the operator had complete control over the cameras and operation of the valves. These are always on wet systems and I'd suspect that they required a PE to bless them.
