Actually, there is no requirement anywhere in NFPA-70 or NFPA-13 (that I am aware) of that requires control valves on the piping feeding electrical rooms nor is there any requirement in either document requiring the sprinkler piping to terminate in the electrical room.
I know MOST electrical inspectors do not want sprinklers or sprinkler piping within "their" room, but to this day, not one (1) inspector can indicate to me WHERE these "requirements" or "prohibitions" are located and I have not yet found them on my own. To expand these thoughts, there are no requirements in the National Elevator Code for control valves nor piping terminations for elevator shafts nor elevator equipment rooms either (removed from the code in 1996), but we fight the same battles day in and day out with the elevator inspectors as well. Unless there are state-specific or local codes / ordinances that mandate these requirements, it simply is a point of contention between the electrical / elevator inspectors and the sprinkler industry. (We do it "to codes and standards" but they want something else.) That being said, we simply try to avoid creating these "conflicts". However, when building construction features or other site conditions are such that to avoid running thru these spaces is so much more costly, we do, at times, choose to battle the "we do not want it" mentality. You certainly want to pick and choose your battles carefully ;-) Ray Vance - SET Chief Sales Designer Wayne Automatic Fire Sprinklers, Inc. www.waynefire.com 407-877-5563 office 321-436-2184 mobile -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of G.

Mike, Usually the Electrical Inspectors that I have dealt with do not want sprinkler main piping that runs through the room. If a main is to pass through then there can be no joints within the space. If a sprinkler head is to be installed then we pipe it in from outside the room and usually are required to install a indicating control valve with tamper switch. G.
