What about the adjacent and unprotected combustible concealed space- doesn't that mean you calc 3,000 SF of that 2,000 SF area?

Now for a specific- Bldg code calls for 1 story, not over 2000 SQ FT - no FDC required-- what about a 4000 SF bldg (sprinklers not Required, but AHJ wants a limited area (less than 2000 SF) sprinklered)-- I know it is up to him/her on the FDC, what are your thoughts? -----Original Message----- From: Chris Cahill [mailto:[email protected]] Sent: Friday, May 07, 2010 12:40 PM To: [email protected]; [email protected] Subject: RE: FDC on Limited Area Sprinklers Even if the fire isn't in the area it doesn't harm anything to hook up to it. They will bring the system pressure up to 150 psi and it will be static. The sign is already required. Now if you want to debate FDC's and are they really needed on any system then sure. Talking simple sprinklers not standpipes. Think if it this way how many times does an FDC make a difference in the outcome? I suspect not often. But in the grand scheme FDC's are not a big portion $$$ of a job so we'll just keep them. Chris Cahill, P.E.

I think an fdc should be PROHIBITED on Limited Area systems- Probable waste of time is the reason. I guess an exception could be if there is a laminated diagram posted at the FDC- 'Attention Fireman- Unless the fire is in THIS area, do NOT connect' Thanks, Brad _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
