Richard, you can do what you are thinking. You will have multiple calc areas and will have to do a mixed calc area, 2,535 sf with both B2B and SSU sprinklers. TYCO’s data sheet explains all of this. If you have a decent water supply you shouldn’t have any real issues.
Thank you, Bob Knight, CET III Fire by Knight, LLC 208-318-3057 From: Sprinklerforum [mailto:[email protected]] On Behalf Of Richard Mote Sent: Friday, October 12, 2018 5:05 PM To: [email protected] Subject: Attic Sprinklers I have an attic that has 2, 24' deep x 86' wide areas. so in those areas I have to use standard spray sprinkler because attic sprinkler haven't been tested beyond 80' according to the data sheet. Most of the rest of the attic is 63'-2" wide and under normal circumstances I would use a row of BB' at the peak and a row of AP at each eave. Question is, is there any reason I couldn't use standard in the 86' wide areas and attic sprinklers everywhere else. Richard L. Mote, CET Rimrock Design Services, LLC P.O.
