High-rise systems have 2 fdv's at the hmd location, pr or not. 500 is sometimes difficult to get through a single fdv and almost impossible to get through a pr fdv.
Tom Great question. I have seen them both ways but the local AHJ's allow us to use the one at the top and the next one down to facilitate testing. Greg McGahan Living Water Fire Protection, LLC 1160 McKenzie Road Cantonment, FL 32533 850-937-1850 Fax: 850-937-1852 It has been a while since I have delved into 14 and I can't get into AFSA's archives so please bear with me. 7.3.2.2 An additional 65-mm (2 -in.) hose connection shall be provided at the hydraulically most remote portion of the system to facilitate testing. Does this mean we have to have two 2.5" hose valves at the top of a standpipe? What about horizontal systems? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum
