Product Overview

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.
  • Powered by 3 AA alkaline batteries for continuous protection, even during power outages
  • The wireless inter-connect feature only pairs with with additional Kidde 900-0225-RF and connect up to 12
  • Voice alert tells user to if the battery is low
  • 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
  • Ionization sensor may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms
  • Interconnect is not required; this alarm also functions as a stand-alone Smoke and Carbon Monoxide detector
  • 10-year limited warranty
  • Many cities and states have created legislation requiring smoke alarms or specific types of smoke alarms in various settings. Certain laws also specify when homes need carbon monoxide alarms or other safety products. Understanding your local requirements can help you keep your home safe from the dangers of fire.
  • Smoke and carbon monoxide detector utilizes an ionization sensor to detect fire hazards and sounds an 85 db alarm when a hazard is detected
  • UL/CSFM Ref. Kidde Part KN-COSM-B-RF
  • Add a Kidde Fire Extinguisher to complete your Fire Safe Home
  • *Check with your state and local fire and Building/Safety codes for specific information regarding smoke & Carbon Monoxide Alarms.

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.

    This is a follow up review. I originally had issues with the first one of these I bought but Home Depot and Kidde were quick with solutions. I like being able to have a push notification go to my smartphone if an alarm is triggered. Also it is very easy to set up in Wink. If you have more than one of these connected to a single wink hub they all show up as one unit.
