Re: 27" Deep Beams Part 2

concrete alone gets that allowance (and then only for SSU/P and CMSA) since it takes a licking and keeps on ticking (even better than a timex). Roland Roland Huggins, PE - VP Engineering American Fire Sprinkler Assn. --- Fire Sprinklers Saves Lives Dallas, TX http://www.firesprinkler.

Re: Sprikler obstruction.

For standard spray sprinklers: 4" from the duct unless a sidewall (you could use a vertical type) and no closer the 6' from the next closest sprinkler. The rules are pretty clear. Unless you can find a sprinkler who's listing negates these rules you're stuck. On Wed, Oct 19, 2016 at 2:26 PM, Art T

Does an upright sprinkler have to be moved when a new duct was added less than 4" away from the existing sprinkler. I understand when a new sprinkler is installed it shall be 4" away from a wall. I have adequate coverage from the adjacent sprinkler in this basement meeting room space. Art Ti

That would be correct. So maybe you can space them so that every other line is positioned to spray under one beam or the other and add to make up that difference. Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] O

RE: 27" Deep Beams

In reality though the edge of the wide flange beams would be 3'-2" apart, with the deflector 5" above the bottom of the beam it looks like the minimum I would need to be away from each side would be 2'-0" to 2'-6". Brian Harris, CET BVS Systems Inc. bvssytemsinc.com F

RE: 27" Deep Beams

Then your deflector can be up to 22" down which would leave you only 5" above the bottom of the beam. At that point you may not have to do much more than lower branch lines. Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesp

RE: 27" Deep Beams

Depends on spacing of beams, deflector distance down from deck, and distance off of the side of the beams. If you can meet some of the obstruction criteria you may not have to add as many. Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun.

I already know the answer but thought I'd ask anyway. I have a mechanical platform that the owner just changed the W18's to W27's, no other way but a head in every pocket right? That's a whole lot of added heads and just so happens it's in the remote area too. Brian Harris, CET BVS Systems
