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.

Battery Operated Smoke and Carbon Monoxide Combination Detector with Wire-Free Interconnect and Voice Alarm is rated 4.5 out of 5 by 477.

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.

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...

The other night when one went off (because we were cooking!) it was very nice that the ones upstairs also started beeping. This is an important safety feature for us as so we could hear an alarm throughout our home.

Rated 3 out of 5 by from We bought three of these and three Kidde smoke detectors... We bought three of these and three Kidde smoke detectors without the carbon monoxide detectors. All 6 were supposed to link together. Unfortunately only the same models have linked. These were easy to install and this model is much nicer than the model without the CO detector.

Each also fits on the base of the prior alarm that I had to replace so I did not have to put any new holes in the ceilings or repaint any thing. Its a good thing.

One thing to note, these install with a single anchor in the center and since I was installing them over existing smoke detector spots where we had wired detectors previously I had to rig up a mounting bracket. Otherwise they worked great!

Quickly configured and installed 6 of these. I had also bought 3 of the fire only but they were not compatible with these so I took them back and had to get three more of the same model.
