Would someone happen to have an old spec sheet for this older fire sprinkler: Central R-1M / 3.9k/ 3/8" ORIFICE 160F
I need to calculate a portion of an existing system but cannot find any sign of this sprinkler online. Tony _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
