Gentlemen, You should be solving this puzzle using 15ft squares to comply with the usual rules with no uncovered floor areas.
Alternatively use a circle of 21-2 1/2 diameter and have no uncovered floor areas. The 15ft circle is not showing the correct solution. The circle is based on the diagonal of the 15ft square. Check that area of coverage and distance between sprinklers does not exceed the rules maximum spacing.

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 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
