Abstract

The acoustic sound of water flowing to/from activated sprinkler heads is used to identify fire location in a region(s). Acoustic transducers, such as microphones, can be located in the vicinity of sprinkler heads. Active heads, spraying water, will produce sounds of flowing water to which the transducers respond. Alternately, acoustic flow sensors can be coupled to sprinkler head feed pipes.
