I believe you are looking for '02-14.4.4.4.3 and yes you don't add any heads under obstructions unless it's ESFR '02-14.4.4.4.4

Box 69 Waverly, MN 55390 Location: 4439 Hwy 12 SW Waverly, MN 55390 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Bitton Sent: Thursday, May 27, 2010 12:19 PM To: 'Sprinkler Forum' Subject: Sprinklers under overhead doors I am looking for confirmation that sidewall sprinklers under overhead garage doors should not be included in the hydraulic calcs since if the door is closed, only the heads at the ceiling would operate and if the door is open, only the sidewall sprinklers under the door would operate. Personally, I see no need to include both heads above and below the door in the design area. However, I found no reference to this situation in NFPA 13. David Bitton, Eng.
