Re: Dry System Size

I would review 2016 edition NFPA 13 7.2.3.6.1 What hazard is Dry system? figure A.7.2.3.7 is very nice (run big pipe for I.T. line) and if you are really hurting "It's Back" 7.2.3.9 subdivide with check valves in a heated room Chuck Bamford On Mon, Nov 1, 2021 at 6:42 AM Brian Harris via

For the record, I directed the development of the FDT program during my tenure as VP of marketing with Tyco Fire Products. The listing of the program was based on its accuracy in duplicating the delivery times of many different arrangements that had been configured and timed by the old Central

Cliff- I agree with you, I'm just gonna split this into (2) systems w/QOD's and be done with it. Brian Harris, CET BVS Systems Inc. bvssytemsinc.com -Original Message- From: Sprinklerforum On Behalf Of cliff--- via Sprinklerforum Sent: Monday, November 01, 2021 10:33 AM To:

RE: Dry System Size

If it's only Listed for Tree Systems, will the AHJ accept it on a loop system? Sounds a little risky. There must be some reason it's not Listed for loops. I'd prefer to be on the safe/conservative side and make it 2 systems. Cliff Whitfield, SET President Fire Design, Inc. 940 Summerbrooke

So that begs to question what are you supposed to do it you have a looped system? Brian Harris, CET BVS Systems Inc. bvssytemsinc.com -Original Message- From: Sprinklerforum On Behalf Of Travis Mack via Sprinklerforum Sent: Monday, November 01, 2021 9:59 AM To:

If I recall correctly, it may work for a loop, depending on configuration, but it is not listed for loops. Only listed for tree systems. Travis Mack, CFPS, CWBSP, RME-G, COC, SET Senior Engineering Manager MFP Design 480-505-9271 ext. 700 C: 480-272-2471

RE: Dry System Size

Brian, Unless they have changed the program in the last year or so, the FDT software will not work if your mains are looped. I believe it only works on a 'tree' type system. Cliff Whitfield, SET President Fire Design, Inc. 940 Summerbrooke Drive Tallahassee, FL 32312 Ph: 828-284-4772  

Re: Dry System Size

Somewhat for my own information, is fluid delivery time calculation required now? My understanding was that it is one option, but that a system over 750 gallons with a quick opening device just has to meet the 60 second water delivery time after instal. Obviously doing the calculation ensures

Dry System Size

I assume with a dry system size of 1200 gallons my options are to add a 2nd dry valve and have (2) 600 gallon system with quick opening devices or run delivery time calc's and see if by chance it's under 60 seconds? If the latter is true what do most use to run theses calc's? Brian Harris, CET
