My question references NFPA 13, 2010; please adjust as needed for later editions. Pages 13-76 & 13-77, Figures 18.104.22.168.2, 22.214.171.124.4, & 126.96.36.199.5. These show vertical & horizontal sprinkler head dimensions from free standing obstructions (i.e. obstructions not connected to ceilings or floors). The sprinkler heads shown are all down oriented. I have a condition where sprinkler heads are upright pendants with top deflectors. My question is: are these figures also applicable to upright pendant sprinkler heads?
