Potter Roemer had one in their catalog years ago we nicknamed "dust pan", I THINK it was U.L. listed. I guess if these things were at least 48.01" wide and we called them a duct, they would be required, not frowned on!

I think the product was listed for the application however not intended for sprinklers only for HAD's . I assume same principals would apply to a HAD as a sprinkler. ASCOA was selling these in 1995 when I left Automatic. I recall customers ordering this product because it was called a Heat Collector and used them rather than a pie plate which was used rather extensively in the State of CA on drops installed in a spec office building with no ceiling installed. After a someone was moving in the ceiling was installed and the Pie Plates where removed. As I recall this was done frequently in Northern CA Sent from my iPhone On Aug 2, 2012, at 1:52 PM, "Brad Casterline" <[email protected]> wrote: > http://www.hss.doe.gov/SESA/Analysis/oesummary/oesummary2002/oe2002-20.pdf > > here's one. > > -----Original Message----- > From: Brad Casterline [mailto:[email protected]] > Sent: Thursday, August 02, 2012 1:26 PM > To: [email protected] > Subject: RE: NFPA 25 inspection of sprinklers with heat collector plates > installed > > http://www.dps.alaska.gov/fire/PRB/docs/codeforum/AutomaticSprinklers_Sprink > lerHeatCollectors.pdf > [email protected] > http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum > > Just FYI-- i'll search for the "evidence" mentioned in the article. > > _______________________________________________ > Sprinklerforum mailing list > [email protected] > http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum > > _______________________________________________ > Sprinklerforum mailing list > [email protected] > http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
