Hi All, I have two questions: 1- In a 6 story residential building that I have Class III standpipes with a single 2½ inch outlet and a 1½ inch reducer connected to 1½ inch hose stations. While NFPA 13 allows 1½ inch hose stations to be directly connected to sprinkler systems, can I connect my Class III standpipe system to sprinkler system?
2- NFPA 13 allows 1½ inch hose stations to be directly connected to sprinkler systems, are these classified as Class II standpipe system? if yes, why there is no requirements in NFPA 13 for 65 psi outlet pressure as stated in NFPA 14?
