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.

  • ionization-sensor technology to detect invisible fire particles
  • Allows for expansion of current hard wire system
  • Radio Frequency communicates with battery operated wireless units
  • When one alarm sounds, others will too
  • 120 Volt AC
  • Smart Touch Hush button silences a low-battery chirp for up to 12 hours
  • Smart Touch Push and hold button to test the operation of the alarm and interconnected system
  • 9-volt battery backup
  • Compatible with Kidde 0919-9999/RF FM DC
