As of January 1, 2011, all homes will need a fire sprinkler system in place. While the majority of American homes have a smoke alarm, this is only an effective tool if someone is around to hear it. If no one is home, your smoke alarm will not be able to put out a fire. A fire sprinkler can. Fire sprinkler heads can be installed using fire sprinkler hangers and must be installed by a licensed professional.
For reference, the official International Code Council (ICC) code states: "Effective January 1, 2011, an approved automatic fire sprinkler system shall be installed in new one- and two-family dwellings and townhouses in accordance with NFPA 13D".
