The Kidde i12060 is an AC/DC powered, ionization smoke alarm that operates on a 120V power source with 9V battery backup. This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. The front load battery operation speeds installation and reduces battery replacement time and effort by eliminating the need to remove the alarm from the ceiling. Alarm is packaged with two universal adapters that allows easy installation when replacing other branded smoke alarm.

  • Front door battery provides easy access which reduces the installation time and battery replacement time
  • Smart interconnect feature
  • Battery pull tab prevents draining battery until permanent AC power is connected - reduces callback's for battery replacement
  • Dust cover provided protects sensors during construction
  • Ionization sensor with nominal sensitivity of 0.50 to 1.06% ft. and temperature operating range is between 40 Fahrenheit and 100 Fahrenheit and unit includes a piezoelectric horn that is rated at 85 decibels at 10 ft.

Rated 5 out of 5 by Love these! After our power went out several times within 10 minutes, our old smoke detectors would go off at random times and were difficult to silence. We also realized the old ones were expired. I purchased the new ones at Home Depot and installed them myself. I didn't need any new connectors because the old smoke detectors were made by Kidde. I changed the housing on the ceiling without any issues. I replaced five of them in less than an hour. An added plus is that we don't have to take the detector down to change the battery when it's low, whereas on the old ones we did. Just push the battery door and it pops open, change the battery, and push the battery door shut. January 7, 2014
Rated 5 out of 5 by Excellent product for the purpose. I needed to replace my 16-year-old wired smoke alarms (should have done it after ten years) and the original product was no longer available as the company was no longer in business. This product was a perfect replacement and the adapters made the install a snap. I now have fresh smoke alarms, good for another ten years with much better battery access and easier maintenance than the alarms that were replaced. And, because I needed four, shipping was free.

Rated 1 out of 5 by Random chirping problem with detectors Replaced two old detectors with the Kidde i12060a and about 12 hours later one started to chirp. I bought another and replaced it and about 6 hours later both were chirping. Searched internet and found solution to random chirping for this model. You must remove 120 volt and battery power then hold down push to test button for 30 seconds. Then install, close battery door, restore 120 volt power and no more chirping. Apparently a code is stored in the detector when 120 volt power is applied before the battery is installed which causes the random chirping. This isn't in the enclosed manual. Thank you China!

Rated 4 out of 5 by A good product well priced I purchased this to replace the old model 1275 (6 units). Installation took about 20 minutes since the 1275 bracket mounting holes were compatible with the new unit. Also the 1275 wire harness was compatible with the new unit so no need to do any rewiring. Housing was easy to mount on the mounting bracket. There is no cotter pin to worry about dropping and losing. Easy access battery compartment is great. February 24, 2014
Rated 2 out of 5 by Ten Percent Failure On Sept 13, 2014 I bought 9 of the Kidde i12060A smoke alarms to replace 10 year old First Alert smoke alarms that the builder had put in the house. That Saturday and Sunday I replaced the nine which included reconnecting the wiring pig tail and mounting the face plate to the boxes. An easy job, but a lot of climbing. I tested them all and the alarms sounded. Done, I thought. Sunday night my wife noticed one of the alarms was chirping (bad battery sound). Monday I located which was chirping and put a new 9V battery in and retested. That night it is chirping again. I took it down and took down one that works. I can see that the battery compartment for the chirping detector has a lose spring floating around and the slide that holds the batter in is either missing or stuck. Time for a warrantee action! Except I have to mail it back to Kidde and pay for return mail. Ridiculous extra cost on a $15 item. I took the broken unit back to Home Depot and they graciously exchanged it for a new one. Thank You Home Depot. It pays to shop locally! There was only one replacement on the shelf. I tested it by pushing on the battery inside the plastic case. It sprung back, so I knew it did not have the same defect. My experience 1 out of 10 failures, but you can test them in the store and avoid the defective units. Pros - I assume they will work as designed and detect fires. They have two nice 110V adaptors, but neither worked with my older First Alert builders models. Rewire was simple. Battery replacement will be easy because the door faces down. Cons - 10 percent failure - lose 2 stars, bigger than First Alert - lose 1 star. September 18, 2014
