I'm working on a four level student housing project (NFPA 13R) at the University of New Mexico where we have a single unheated trash room that can't be reached with the wet sprinkler piping. The only options I'm aware of are either a dry system, preaction system, or an anti-freeze loop. Since either option would only be serving a single sprinkler head, I found that in NFPA 13, 2007 section 8.16.4, listed heat tracing is allowed but must be specifically listed for use on branch lines and must be supervised, and specifically listed for use on branch lines.
Of course, this head is at the end of the system, so I'm wondering if there's anything that wouldn't have to be traced all the way back to the riser. I'm also wondering if this would even apply since we're using NFPA 13R on this project. Thanks in advance for your help.
