what it takes on stuff like this. It helps when the plan reviewer is actually a very nice person. He acknowledges that they take a different interpretation, and understands the other side, but this is what their department has arrived at. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct

I was informed from the AHJ that they would accept a "technical question" answer from NFPA only if he agreed with it. Otherwise, it would take a formal interpretation. As I said, some days you just really have to love what you do. Thankfully I do. Travis Mack, SET MFP Design,

for area of sprinkler in 13R. So, you may have to choose the larger k factor residential sprinklers. We typically do a 4.9k pendent, but you may have to go to the larger ones depending on your requirements. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax

You can only have a maximum of 4 QR sprinklers per dwelling unit, not just compartment. If you need more than 4 standard spray sprinklers, you can't comply with 13R. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107 email:tm...@mfpdesign.com

I think the issue is that ESFR sprinklers can’t be less than 8’. You can do <6’ with SSU/P sprinklers as the standard references baffles in those instances. ESFR is a different animal. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-

I didn't even read that. NFPA 13 uses nominal k-factors. There is no difference in a K17 and K16.8. Look in Chapter 6. You will see anything with a range of 16.0-17.6 is to be calculated at k16.8 Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505

Dig into the areas of 13 about that. I don’t have the reference off hand, but you have provisions to use sprinklers in different orientations for the exhaust duct. So, just put a pendent sprinkler in the horizontal position. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert
