Product Overview

  • Battery-operated smoke and CO alarm; 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
  • 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
  • Smoke and carbon monoxide detector utilizes a photoelectric sensor to detect fire hazards and sounds an 85 db alarm when a hazard is detected
  • 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.

10-Year Sealed Battery Smoke and Carbon Monoxide Combination Detector is rated 3.8 out of 5 by 240.

I had purchased this item in 2016 and left this review on 10/03/2017: Purchased this item less than a year ago. It set off a false alarm when it was about 6 months old, but we were able to reset the alarm. About 3 months later another false alarm. This time our condo security had to access our condo. He called me at work and could not get the alarm to reset. I told him to rip it off the wall and break it open. Could not send unit back to Kidde because the unit was "damaged". Left a message with Kidde customer service but still no response. -------------------------------------------------------------------------------------------------------------------------------- After leaving this review on the Homedepot site, Kidde contacted me and sent me a new unit. I received it on 10/17/2017. Since then I have had numerous false alarms. 11/02/17, 11/06/17, 04/04/18, 06/01/18, 07/14/18, 07/19/18. I live in a condo and the neighbors and the association do not appreciate these false alarms. One good feature about this alarm is that it is loud and will wake you and the neighbors up from a deep sleep. DO NOT BUY.......

Rated 4 out of 5 by from Kitchen fume resistant The mounting ring on this unit is strange, only about the size of a USA 50 cent piece. (See attached photo of similar unit with same mounting system.) So they tried something different by having two different ways to mount it, one with traditional screws and anchors, and the other with a central drywall anchor screw. Neither gives me much confidence. To activate the unit, you have to give it a hard twist on the mounting system, and it felt like I was going to rip it right off the ceiling. I really would prefer a different, more traditional mounting system. Mounting issues aside, this unit is full of features. CO detection and kitchen fume resistance were why I got this unit. We have wired detectors in our house of ionization type, so the fact that this unit is photo-electric is a perfect complement for our kitchen area. The unit has passed our "broiler test" with flying colors. No more fanning the fumes from the detector. It can handle a few broiler fumes, no problem. I can't speak for the CO element. That's something I hope to never test. It is comforting to have as a second CO unit in our house.

Right out the box two of them were duds! None of the "troubleshooting" worked and they were recently manufactured. It's difficult to have faith in a product that does not come tested and ready to work, and makes one insecure that it will do it's job when needed.

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.

They don't meet the code here where the co2 and fire alarm must be able to distinguish to the occupants, which alarm is going off.
