Smoke alarms can save your life and the lives of people you love. Make sure your home has smoke detectors, change the batteries regularly and replace when needed.

Homes with Wired-in Smoke Alarm Systems - Indiana Fire Code

Built in 1998 or later:

  • If your home was built in 1998 or later, Indiana fire code requires smoke alarms in common areas on each level of the home and in each bedroom.
  • The updated fire code also requires that smoke alarms have a battery backup in case of a power failure.
  • The alarms are "interconnected,” meaning that they communicate with each other via an extra wire in the system. If one alarm senses smoke, it alerts the entire system.
  • If your house is ten years old or more, and you have the original alarms, it's time to replace your system.

Built before 1998:

  • Typically, alarms were only installed in common areas on each floor and not interconnected.
  • In most cases, alarms did not include a battery backup.
  • If you still have your original alarms, you are past-due to replace them with newer alarms.

No matter what kind of smoke alarm you have, most manufacturers recommend replacing your smoke alarm when it is ten years old.
