Cesar, You will have to go by the listing for the sprinkler. If it is specifically listed for Light Hazard only, you can't use it for OH. If it is listed for use in NFPA 13 occupancies, it could be used in Light or Ordinary. The Tyco RFII can be used in on OH occupancy, such as a retail store. If you are talking extended coverage, that may be a different animal.
