The Kidde Hardwire Interconnectable Ionization Smoke Alarm with Battery Backup makes it easy to expand the protective coverage of your current interconnected system. A single 9-volt battery is all it takes to provide backup protection to you, your family and your home or business in the event of a power outage. The alarm uses wireless technology via a radio frequency to both transmit and receive messages about the presence of invisible fire particles, so when 1 smoke alarm sounds others also become activated.
