We are upgrading the sprinklers in a bay where the insurance company wants it to comply with NFPA 30, meaning I will have to use 286 degree sprinklers. We will be removing the existing piping and sprinklers to install new in this bay. The other bays in the building will have 212 degree sprinklers still. The bays are separated by 30" steel beams, so the branch lines and sprinklers will be above that beam and separated from the other sprinklers. I know that NFPA 13 (2010) 8.4.6.4 requires draft curtains for for ESFR sprinklers when using with standard sprinklers, and I thought there was something elsewhere about temperature separations, but I cannot find it. Now the insurance company wants to know if the 30" deep beam is enough separation. Can any one refresh my feweble brain and tell me where it's at in 13? Thanks!
