Is it required to install a sprinkler head in a small telecommunication closet (not located in a residential building)? Is there a minimum size to be considered according to NFPA 13?
Aside of residential occupancies, I cannot find anything in regards to it in NFPA 13.
NFPA 13
Sprinklers throughout...
If under IFC there are a few omissions, but your case would not be one.
