You stated "lone sprinkler", there are no other sprinklers in the structure?
If not, what supplies this system, what pressure, what gpm, what pressure was the sprinkler system tested to, what material was used for the sprinkler system, etc., .... ?
If so, then there should be more sprinkler heads in the basements for the coverage required of sprinkler systems.
