The tyco sheets from 2010 include cross-slope diagrams. Those were removed in the 2014 data sheets. I figured it was because of the addition of the 'sloped ceiling' section in 13R and D.

Is it the intent that residential sidewalls can be arranged so they discharge cross-slope and up-slope? I don't think so ...

The picture shows only pendants, but it is in a section separate from the pendant/sidewall positioning sections. Section 10.2 also makes several references to general and sidewall spacing under slopes. Also - the tyco listings previously had multiple diagrams showing how to position residential sidewalls under sloped ceilings. Those were removed after the 13R/D code language was changed to the generalized description of heads under slopes.

Can a sidewall be oriented so it discharges down-slope? You comment sent me scurrying to our tech data library and also to NFPA 13D and 13. Both standards are mute regarding the positioning of residential horizontal sidewall sprinklers on/under sloped ceilings. Viking tech data sheets say to refer to the appropriate standard. Tyco says their RHSW sprinklers can be used under sloped ceilings but no specific positioning criteria is offered. If we use the spray sprinkler criteria, the sprinklers have to be oriented so they are placed at the peak of a sloped ceiling and spray downward. Am I missing something somewhere regarding RHSW sprinklers and sloped ceilings? Steve L.

Matt From: Sprinklerforum [mailto:[email protected]] On Behalf Of Richard Mote Sent: Tuesday, March 07, 2017 7:50 AM To: [email protected]<mailto:[email protected]> Subject: Cabinets Against a Wall NFPA 13D, 2017 (the edition currently in force in PA) 8.2.5.6.3 Where sidewall sprinklers are more than 3 ft. above the top of cabinets, the sprinkler shall be permitted to be installed on the wall above the cabinets where the cabinets are no greater than 12 in. from the wall. We have a case that meets all of the above criteria except for a 2" wide crown molding around the top of the cabinets, so the overall width is 14" around the top of the cabinet. Obvious solution is put the sprinkler on the other end of the room, however that wall is a rated wall with a un-conditioned space on the other side. Any sugestions?
