Do these operate off a 10 year battery only?
Asked by: cloe
They are warrantied for 10 years... The batteries 3-AA don't 10 years. Although some fire alarms do have Li-Ion battery that last ten years.

Rated 4 out of 5 by from Worked as expected, easy set up to operate wirelessly... may even be called fun! Very easy to set up as individual alarms -- like pull out of the package (takes a sharp knife!) The wireless set up was easy too -- just put on your glasses and make the DIP switches all have the same number and you are set and the fun begins. Of course you must in stall the 3 AA batteries also. Push the test button on one and it give audible and shrill beep we all know and hate, but a voice comes on and says "FIRE" and then it beeps and speaks again in testing the carbon monoxide. I mounted mine upstairs and down. At some point when wife upstairs, I pushed the test button down stairs and it went thru the "test cycle" and she got to hear it work upstairs as the wireless system alerts all areas when either alarm activates. Do we lack real fun in our life if this was FUN? The only reason I gave 4 stars and not 5 was because I foresee having to change batteries more often than with more typical 9V batteries found in other fire alarms. Time will tell...

We bought them because we were required by code to have interconnected smoke and carbon monoxide detectors, and these are some of the few battery operated ones on the market. They go through batteries very quickly (about every 3-4 months), which I suppose is to be expected from the wireless feature. We've had these nearly two years. After about 15 months of use, they began going off randomly, at random times. This happens about once a month. Sometimes one in a bedroom behind a closed door will start alarming. The batteries are fine, nothing has changed in the room, but the alarm is going off. It's extra fun when this happens in the middle of the night. When the random alarm goes off, the interconnected feature does NOT work. Only one alarm goes off, not all the detectors in the house. When tested, the interconnected feature still works (i.e. when I press the test button, all detectors in the house cycle through the alarms), but this makes me dubious the interconnected feature would work in case of an actual alarm.

They worked great at first. Easy to install just one screw, easy to sink them putting in the same code for each one. Make sure you put the code in before putting in the batteries to save time as it is behind the battery compartment. Then after 3 months one of the alarms started chirping every few minutes. When looking it up it was low battery. I put in new batteries then it had a constant chirping noise that would not stop. When looking it up it was a defective unit. The other two have been fine so far it's one bad unit.

Smoke and Carbon Monoxide alarms that are linked and all alarm at the same time when one is set off, and battery operated -- no wiring. Also, I like that they use AA batteries instead of 9V batteries like the old style smoke only.

Unfortunately, that means they only interconnect with the same model, and not with other Kidde wire free interconnected smoke detectors. I confirmed this with Kidde support. This was really unfortunate and I had to return the units.

I have one unit per floor in an old 1940's bungalow with plaster walls and the wireless signal has no problem sending alerts to the other units. Setup was a breeze with the simple toggle switch design to get all units on the same frequency. Highly recommend these for Fire/CO2 detectors!
