Here is what I was thinking. I agree if using standard coverage sprks Examples 2 and 3 would need a sprk added, but it is not due to the distance between B and C. Due to the round pattern and square spacing I believe Example 4 is (at least) equivalent to Example 1. Anyone with me on this? thanks, Brad _____ From: Sprinklerforum [mailto:[email protected]] On Behalf Of Kenneth Berman Sent: Sunday, June 12, 2016 2:03 PM To: [email protected] Subject: Re: Angled Wall Spacing using extended coverage allows further distance from walls, which brings heads closer than 21-2 1/2.

Example 3 is closer to being correct, as the sprinklers at B and C aren't more than 7'-6" from a wall, measured perpendicular to the wall. The error, to me, is the distance of 21'-2½" between B and C. I don't see how that would be allowable, even if you were using extended coverage sprinklers. Table 8.8.2.1.2 limits the distance between such sprinklers, with the maximum being 20'-0" in OH and LH occupancies. I don't see how that would be allowed.

If you draw a 15X15 square template on your drawings you will see an obvious void of sprinkler coverage requiring protection.

What I'm concerned about is the distance between sprinklers B and C. In example 3 all the sprinklers are spaced correctly from the walls but B and C are 21'-2 1/2" apart. The way I understand it, they still need to be 15'-0" along that wall, even though they're spaced correctly from every wall. Is that correct?

What I mean is walls not at a right angle. The PDF I made in the link below really helps explain it. In example 1, four heads are spaced correctly at 225 sq. ft. In examples 2 and 3 one of the walls is angled. My question is, are either example 2 or 3 correct, or are they both wrong? My thought is that example 2 is incorrect, and for example 3 to be correct there would need to be an additional sprinkler along the angled wall between sprinklers B and C. <https://www.dropbox.com/s/7fg0l79rtwbawne/Angled%20Wall%20Spacing.pdf?dl=0> https://www.dropbox.com/s/7fg0l79rtwbawne/Angled%20Wall%20Spacing.pdf?dl=0 James _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org -- Benjamin Young _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
