From a code compliance standpoint Underwriters Laboratories is one of appx 22 Nationally Recognized Testing Laboratories (NRTL). Interestingly UL 199, 1626 etc. are the defacto standards for fire sprinklers which any of the other NRTL’s would use to test and list a fire sprinkler (aside from perhaps FM Global) should they choose to do so. So it’s not really UL itself but rather does the sprinkler comply with the applicable UL Standard. A UL Listed Quick Response Fire Sprinkler is a listed quick response fire sprinkler.
As for insurance companies and what they want well ask them, so long as it meets the applicable code its code compliant.

FM does not require Quick response, so the fact they don’t accept it as QR is irrelevant. Your real world AHJ should accept the UL listing.

FM does not have approval for those sprinklers. You have to get a variance from the FM reviewer. Then you may be battling an AHJ that says they don't recognize FM and you have to follow NFPA 13 criteria. These are real world scenarios that come into play daily for many of us. Not everything comes down to 15 significant figures and exponents to the 1000th power. Sometimes it is just dealing with what is available and playing the game.

SURVEY SAID! it's a tie. I.O.W., I.M.H.O., (opinion being entire weekends spent jacking with it bcoz i been divorced for 16 years and the kids are grown and on their own) activation is more about ceiling height, temp rating, and spacing than QR vs SR.

You then playing to two masters and which one will give. Probably FM but you have to get approval and ad was earlier stated your best served by getting it in writing.

And last I looked there are a number of QR concealed heads that are FM approved, only as standard response. Since your AHJ presumably uses NFPA/UL, they’re QR heads, and since FM doesn’t care, it’s fine that they accept them only as standard response. Since our client is all FM it’s always a picnic trying to design systems that satisfy both because it’s easier to deal with the AHJs without having to explain the FM design criteria in detail (they do accept them when its an issue though). > On Oct 6, 2016, at 6:29 PM, Mark Phillips <markphill...@webolton.com> wrote: > > Just ask their rep for a variance in a written letter. > > Have done many a hospital this way. > > Sent from my Verizon 4G LTE Droid > On Oct 6, 2016 6:13 PM, Scott Holman <shol...@rlhfp.com> wrote: > > Hello All, > > > > I have an FM job where the customer wants concealed sprinklers in light > hazard occupancies.
