It's not a valve controlling a fire protection water supply by definition, so I would say that it's okay to not electronically supervise. Would opening the valve ring a flow alarm? If not, that's a consideration, but not a compelling prescriptive, IMHO.

I am going to install a 4” butterfly valve on a sprinkler manifold. This will give us an outlet to perform a Forward Flow. Does the valve need to be monitored or will it be OK to use a chain to lock the valve in the closed position? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
