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.

  • 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

Rated 4.7 out of 5 by 10 reviewers.
Rated 5 out of 5 by Easy Installation AC wired smoke detector was fairly easy to install; wirelessly interconnected with 4 battery powered. When tested, detector sounded alarm as did the others. One product I hope I never have to 'use'. July 1, 2014
Rated 5 out of 5 by worked great for what we needed We had a remodle with three bedrooms with split floor plan in condo.The ceiling from one side to the other was concrete.And no way to interlock detectors without a lot of wall damage. saved time and money. April 16, 2013
Rated 5 out of 5 by Great product I am a licensed electrical contractor. This item is not readily available on the market. I have had tremendous success with this item and my customers are ecstatic that they now have interconnected smoke alarm protection and no drywall damage. April 17, 2010
Rated 5 out of 5 by Excellent This alarm allowed us to interconnect the new smoke alarm chain in our new addition to the alarms in the old portion of the house. Couldn't have been simpler to install and set up! Now when any one alarm is triggered, they all go off. September 11, 2012
Rated 5 out of 5 by Great product This fire alarm is great because of its wi-fi technology that connects each alarm without having another wire pulled. When one alarm sounds the other alarms activate for added safety. April 17, 2012
