My question references NFPA 13, 2010; please adjust as needed for later editions. Pages 13-76 & 13-77, Figures 188.8.131.52.2, 184.108.40.206.4, & 220.127.116.11.5. 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?
