I'm new in using NFPA 13 and I would appreciate your help for the following matter:
For class IV rack storage according to NFPA 13 I have two options to design my sprinkler system: -control mode density area -large drop sprinklers and specific application control and mode sprinklers. According to table 16.2.1.3.2 I have to use fig 16.2.1.3.2(d) curve E. For me to reach sprinkler density I must use ELO sprinkler K 11.2. My question is: can I still use control mode density or do I have to use large drop application, because according to table 16.2.2.1 for K 11.2 sprinkler the minimum sprinkler operating pressure is 3.5 bar for class IV. This is an existing system and the pump can't deliver that much pressure. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
