My question references NFPA 13, 2010; please adjust as needed for later editions. Pages 13-76 & 13-77, Figures 184.108.40.206.2, 220.127.116.11.4, & 18.104.22.168.5. 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?
