Kidde offers the first UL-Listed wireless smoke alarms. The Kidde Wireless System includes battery operated and AC powered alarms to fit almost any residential structure. The Kidde Wireless System is easy to install and only involves a few simple steps. The first step is to determine what type of smoke alarms are currently in your home: battery powered, hardwired, or interconnected. 

Worldwide, fire causes 20 times more deaths than tornados, hurricanes, earthquakes, and floods combined. Having working smoke alarms dramatically increases the chance of survival when a fire occurs. From battery operated to hardwired to interconnected, our smoke alarms will fit a home's specific needs. Our smoke alarms meet or exceed standards set by Underwriters Laboratories, an independent third-party testing agency, as well as guidelines set by the National Fire Protection Association.
