What I meant by 'wavy' as opposed to flat. Brad [email protected] _____ From: Sprinklerforum [mailto:[email protected]] On Behalf Of Brad Casterline Sent: Wednesday, March 29, 2017 11:22 AM To: [email protected] Subject: RE: 1x6 Slatted Ceiling I would be skittish about that Ron because I think I understand the reasoning behind the max 7'-6" between the beams and the max 6" below the plane of the bottom of the beams--I think it is to make the bottom of the ceiling jet 'wavy' as opposed to flat like you get with smooth ceiling. I've been modeling this in my head since yesterday, so I got the talking part done. I'll check the tenability conditions at 6'-0" A.F.F. with smooth ceiling @ 12" deflector vs 18" deflector.

Rooms less than 300 sqft with full height walls should facilitate heat collection better than exposed beams. If the construction is called panel then the deflector could be at 18" and eliminate the sprinklers above the slats?

You could then locate the pendent bulb in the gap at 9'-0" A.F.F., and the bottom of the slats at 1" above the deflector. Brad From: Sprinklerforum [mailto:[email protected]] On Behalf Of Gregory Lindholm Sent: Tuesday, March 28, 2017 2:31 PM To: [email protected] Subject: 1x6 Slatted Ceiling We have an office that has the grid ceiling at 10'-0", and we have a 8' x 12' area that has 1" x 6" boards as slats (The slats end up being 1x6's, 12' long), that are about 6" apart. The top of the slats are @ 8'-8" (1'-4" below the ceiling). This slatted area is in a 12' x 16' room. I believe that we obviously have to have a normal layout of sprinklers at the grid ceiling, but we would also have to have something below, because the slats would break up any pattern from the ceiling level heads. My 1st assumption would be a level of heads with the deflectors just below the slats, but how would they ever activate, with no way for the heat to collect down to them. This is one that I have never run into. ???? Greg Lindholm
