About This Product

The Kidde 2-in-1 Battery Operated Wire-Free Interconnected Combination Smoke and Carbon Monoxide Alarm with Voice provides two important safety devices in a single unit. The alarm is powered by 3 AA batteries and features a voice alarm that warns of smoke or carbon monoxide danger. The voice alert also lets you know when it's time to replace your batteries. This alarm features wire-free interconnectivity with other Kidde KN-COSM-B-RF units (up to 12 total). If one unit is triggered, all interconnected alarms will sound. Wire-free interconnectivity allows for easy interconnect setup and eliminates the need for expensive rewiring. You can even install this smoke detector in a detached garage or workshop and be alerted by another detector in the house.

  • Voice alarm announces "Fire! Fire! Fire!", when a smoke or fire hazard is detected and announces "warning! carbon monoxide" when a CO hazard is detected
  • Smart touch button temporarily silences nuisance alarms, low battery chirps, and tests the operation of the unit and interconnected units
  • Internal timer reminds you to replace your unit after 10 years to ensure the most reliable protection

Q:Do these ever expire (i.e. some detectors are good for 10 years and that's it), or do these last 'forever' as long as I keep changing the batteries?
by|Apr 15, 2024
1 Answer
Answer This Question

A:  All smoke alarms, per NFPA code, have to be replaced every 10 years and all of our carbon monoxide alarms are required by UL standards to have an end of life feature after their 10 year lifespan. These alarms last 10 years.

    Answer This Question

    A:  Hello. No, but we haven't made the HomeHero in about 10 years and they only had a 7 to 10 year lifespan. It would be getting to be time to replace them all anyways.

                Issues with faulty unit that has 10 year warranty
                We purchased a six pack of these 3 years ago and had no problems until recently. We now have one unit that is causing false alarms which makes the other five units go into alarm. This is a smoke free house and all units are located in large open areas away from the kitchen . Unable to find a replacement but hoping Kidde will warranty since they do have a 10 year warranty.

                Response from Kidde Product SupportMay 3, 2022
                Hello. False alarms are most commonly caused by something interfering with the sensor. To clean, after disconnecting the alarm and removing any removable battery: hold the unit by its edge and thoroughly blow through the gap on the side of the unit with compressed air (like keyboard cleaner). We recommend cleaning out all of your smoke alarms at least every 6 months to a year and at this point we would recommend cleaning out all of your other alarms as well as a preventative. It is also possible that some of your alarms may be in one the locations to avoid listed in the owner's manual. This would especially include alarms being installed within 3 ft (.9m) of a forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. We recommend that alarms not be installed near vents, flues, chimneys, or fans. We recommend that alarms not be installed near doors or windows near areas directly exposed to the weather. We strongly recommend not to install these alarms in garages, attics, and crawl spaces as you will get temperatures, dust, insects, and chemicals that can cause nuisance alarms. Try cleaning out the alarms If you have the issue again, call us with that alarm in hand at 1-800-880-6788 so we can get this resolved for you.

                  No mounting bracket
                  I don't even know how these work, because we haven't been able to mount them. There is no little mounting bracket included, and judging by the other reviews, this is a frequent problem. If you want to buy this, put the batteries in, hang them up and be done - this is not your product. Now we're waiting for Kidde to send the brackets through the mail. Batteries are included, so there's that.

                  Hello DeeGee,
                  Thank you for your input and we apologize that the mounts were not with the unit.
                    Simple install & wireless (not WiFi) interconnection works very well.

                    Easy to set up! Glad I made the switch to these. They work together when activated. I even put one in the garage in case something happens in there while were sleeping. If it detects smoke or carbon monoxide it will communicate with the one in the hall by our bedrooms to let us know!!!

                    Easy to install and link together. They are very loud when they go off so I have no doubt I will wake up when they go off. When one goes off they all go off.

                    These are a good product whether individual or "3-pack". The wireless connection was exactly what we needed and these are on all 3 floors and connect without issue. Easy setup and install with one screw. Tested one set off, and it will set all 3 off. Which I think everyone needs because you are not going to hear an alarm 3 floors away while sleeping etc. Hoping that the technology does work in an actual event while sleeping, but I believe this is still the best bet (bang-for-buck) for safety. I still have all my other separate smoke and CO alars, and while I am not home, my Leeo device listens for alarms and calls me in an event. Do not mess around. For ~$100 (daily deal) it is worth it. Even regular price is worth saving a life and possibly a house/building.

                    Installed 8 of these in my home in the fall of 2016. All of them activated within seconds one time since then from kitchen smoke. They are loud and sensitive. The carbon monoxide detector has not activated yet and I hope it never does. Look for the 2 pack ($80) if purchasing these as opposed to $50 for a single unit. I feel good knowing these detectors are protecting my home. The batteries haven't been changed yet and no low battery indication so far. I will change them in all 8 units when the first one indicates such then annually after that. I highly recommend these to anyone replacing or a new install.

                    Setup was very simple. Testing went exactly as advertised. Pressing the test button on one unit made all units sound the alarms. Once installed in the house, the lit match test near one unit worked flawlessly. The unit detecting smoke sounded the alarm first and announced "fire detected". Immediately followed by all three other units giving the same alarm. I purchased 4 of these at one time to replace aging units. The price for the twin pack was quite low. Get some piece of mind and get these.
