I suspect it would require an RPZ ahead of it if installed off fire protection water in these parts. Around here no chemical can be added to a fire protection water source without triggering an RPZ. That probably applies to connecting to a plumbing supply. On this unit you have both hot water and cold water connections. The hot is for the wash down. Internally the hot and cold manifold together. The cold valve is supervised. The hot valve is not. Its not quite clear if the wash down goes to the suppression nozzles or not. Its hard to believe the wash down is also applied into the kitchen appliances as shown in some of the piping setups in addition to washing down the grease filters.
