Product Overview

  • Battery-operated smoke and CO detector; no hardwiring required
  • 10-year lithium battery lasts the life of the alarm
  • Protection during power outages and no low battery chirps
This Kidde 10-Year combination smoke and carbon monoxide detector is easy to install and alerts your family when a fire or elevated carbon monoxide levels are detected in your home. Smoke and CO sensing technologies work together to detect real fires faster and reduce cooking-related nuisance alarms. Combination alarms should be placed outside each sleeping area and on every level of the home. This alarm is powered by a 10-Year sealed-in, non-replaceable lithium ion battery. No hardwire installation required and no need to change the batteries over the 10-year life of the alarm. Simply replace the entire unit after 10 years.
  • Smoke and carbon monoxide detectors should be installed in a central location outside each sleeping area, on every level of the home, and in other locations where required by law
  • Reduces nuisance alarms by adjusting smoke sensitivity when carbon monoxide is not detected in order to better discriminate between a real hazard and a false one
  • The 10-year lithium ion battery is sealed into the alarm and cannot be removed, preventing unwanted tampering and ensuring your alarm is always on
  • No hardwire installation required
  • Smart hush feature temporarily silences nuisance alarms
  • Never replace a battery during the 10-year life of the alarm
  • No low battery chirps; internal timer alerts you to replace the entire unit after 10 years
  • Alarm is equipped with test/reset button which tests the alarms circuitry and horn and resets memory after an alarm has sounded
  • Alarm will automatically activate when attached to the mounting bracket
  • Green LED light indicates that the alarm is working properly
  • Alarm features a photoelectric sensor which may detect visible fire particles (associated with slow smoldering fires) sooner than ionization sensors
  • Alarm uses electrochemical sensor to detect carbon monoxide
  • 10-year limited warranty
  • UL/CSFM reference model P3010K-CO
  • Available in a 3 pack

Questions & Answers

What happens after the ten year battery wears out? Do you throw the whole unit away and purchase another one?

Asked by: AngieAAB
yes, Angie, and only use UL / NFPA recommended ones. most retail outlets only sell them. also don't compromise price for quality ( its not worth the safety risk)

Where do you mount these alarms?

On the ceiling? Wall? Do they need to be up high in the room? Do you need an electrical source for them?
Asked by: Wade6
Look on the web site for (or call) Your Local Fire Department. They should have a list of approved locations, quantity and other information regarding the placement and locations of fire alarms (and how many combination smoke & CO alarms) are required in your home.

Is it wired into the house? Does it meet or exceed all building codes?
Asked by: Doug
10 years is pretty much the limit on the technology. ( much like a car or smart phone) they should be replaced at least after 10 yrs, or malfunction.) it is NOT recommended that you replace the power source at the end of that period, but replace the unit. most of us recommend that when you replace the device, place a date on the inside, so you, ( or if you move) the next occupant, knows when they were installed.

Worry Free 10-Year Kitchen Sealed Lithium Battery Operated Combination Smoke and Carbon Monoxide Alarm is rated 3.8 out of 5 by 230.

These alarms only lasted 2 years before going off in the middle of the night for no reason. They were expensive. Around $50.00 each. We bought them thinking that it was a good investment. Home security for 10 years! ....what a scam! My son found if you smother them with a thick pillow they eventually quit. One of them we smashed with a hammer because it wouldn't stop. I would rather change a cheap battery than shell out this much money for rubbish. We bought 5 of them. One of them we paid more for because it talked. Kidde, you are getting rich by taking advantage of people! Buyer beware.

I bought this smoke alarm as well as 3 other regular living space smoke alarms 2 years ago. I have now thrown three of the four in the trash as they all started going off for absolutely reason and would not stop. I have a separate carbon monoxide alarm that I used to make sure that wasn't the issue when the first one went off, and it turned out everything was fine. The others were just smoke alarms and went off with no smoke present and then wouldn't stop even when taken outside, which meant I had to turn the screw in the back to shut them down, rendering them useless. I tried to reach the company because a ten year smoke alarm should at least last half of that time, but they never even bothered to return a call or an email. Don't waste your money.

Last night it went off in the middle of the night and could not be silenced. This model is disposable, meaning the battery cannot be changed. In other words, the battery cannot be accessed, because the unit cannot be disassembled. On the underside of the unit, there is a layer of card stock, which must be penetrated with a screwdriver to disable the battery. Once the battery is disabled, the unit must be disposed. Horrible design, especially considering how often it gives a false alarm.

Installed the kitchen smoke detector/CO alarm yesterday, and it went off today while making breakfast. So the idea that this was specially designed for kitchens is probably just a Kidde marketing lie. I also installed three bedroom smoke detectors in other rooms in the house, and now I'm worried they will go off prematurely.

I bought a pricier detector which after a few months would intermittently sound alarms. Even after cleaning which showed no signs of dust or insects the alarm would, usually at the most inconvenient times, go off. Not just an operational chirp but a full on alarm. This one seems to be working better.

The State of Maryland now requires that smoke and carbon monoxide detectors be installed outside sleeping areas of homes. The State requires that the battery cannot be removed by residents. I am sure that the property and casualty insurance industry supported this also.

Not having to worry about batteries for 10 years sounds great. 10 years is based on manufacture date, some may be months old or older when you purchase. If you can check dates on units before buying.

So whats not to love? Meets my expectations. Installation was not as simple as it could have been: seating the unit tp the connector requires patience.
