I am not a firefighter myself, but have worked around many for over 10 years, most of whom have never even hooked up to a sprinkler only FDC, 30 year career types in many cases. Seems that the sprinklers do such a fine job there is not much to take care of.

Limited area does not require to be monitored- although there will be local audible alarm- I guess when you get there, if the bell is ringing, and you need to, go ahead and take the time to connect? -----Original Message----- From: Richardson, R [mailto:[email protected]] Sent: Monday, May 10, 2010 9:22 AM To: [email protected] Subject: RE: FDC on Limited Area Sprinklers If the scenario is AHJ say so - we do it, no questions allowed, then make the AHJ decide this question as well. Seems kind of hard to consult for a project when there is an unbridled authority making up stuff in the first place. Personally if I were the consultant and was not inclined to question the AHJ, I would not specify an FDC in this situation.

Your statement that the "The bldg is 'too small to REQUIRE sprinks', but the AHJ wants some heads in a particular area." is worthy of further exploration. What exactly is the hazard at issue here anyways?

The area is actually quite a bit less than 2000 SF. The bldg is 'too small to REQUIRE sprinks', but the AHJ wants some heads in a particular area. EC is correct to stay less than 20, though, bcoz there is some 'above and below'. All heads will be calc'd (on one level). It is in the consulting stage, so by the time it is bid, the Sprink will know whether or not to include the FDC. I took the '2000 SF building' to mean 2000 SF of sprinklers, remembered we deal with emergency situations, and thought about the 'probable waste of time' thing for Limited Area sprinklers.

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) _______________________________________________ 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)
