Hello Ronalf. It sounds like the alarm has not be activated or was deactivated. Try putting the alarm onto the small round bracket that it comes with, and do so firmly and quickly, pressing the alarm against the bracket. The alarm is turned on when you put the alarm onto the bracket. If that doesn't fix it, check to make sure no one has broken through the label and turned the screw slot on the back of the alarm next to where it says on and off. If the alarm has been turned to off, the alarm will never work again. If it is neither of these, call us at Kidde Product Support at 1-800-880-6788 with the alarm and bracket in hand and we will be happy to help you. Read Less

Rated 4.4 out of 5 by 38 reviewers.
Rated 5.0 out of 5.0 by Best Smoke/Carbon Monoxide Alarm ever! The best smoke and carbon monoxide alarm I have installed. Comes with a 10 year li-ion battery. You never have to worry about changing the battery for the next 10 years, one of it's best features. Another great feature is it has both a voice and beep warnings. It will alert you to smoke/fire detection; carbon monoxide detection, and end of life of the alarm battery. You can't ask for a better smoke/carbon monoxide detector, one of the easiest to install. June 23, 2015
Rated 5.0 out of 5.0 by Easy install and 10 year battery win win Install is as easy as it gets, one plastic screw into drywall. There are also screws and plastic inserts provided if you are installing on something other than drywall. Also a 10 year battery, thats a plus too. I never seem to have a 9-volt battery around when I heard the old one beeping telling me it was time to change. And then it would be weeks before I remember to change it. The warning for smoke and CO are loud and distinctive. There is also a voice warning to let you know if the alarm in smoke or CO. June 23, 2015
Rated 5.0 out of 5.0 by Nice compact unit worry free no battery replacement This SMOKE AND CARBON MONOXIDE COMBINATION ALARM WITH VOICE WARNING is a very compact unit no need to worry about changing battery as it has a built in lithium battery that will last 10 years no more removing batteries to silence the alarm. The voice command is a good feature as you can tell if the issues is smoke or carbon monoxide. June 9, 2015
Rated 5.0 out of 5.0 by Nice, but too easy I had expected this to be a direct replacement for my existing wired smoke detector, but it is not. Instead, it has a 10 year battery. It also provides a small 1-1/2 inch diameter mounting button, instead of the 5" round mounting plate that was there before (that covered the electrical box for the plug). So I bought a blank plastic cover plate to cover the electric box and mounted the button to the plate - this way I covered the location where the old smoke detector was mounted to hide the electric box. So the upside to this alarm is that it is incredibly easy to install - especially where no alarm existed before. The downside is that replacement is not as simple as plug and play with the previous attachments. Also, the 1-1/2 button is how this turns on, so you must use it. The other downside is that my old wired alarms sounded all the alarms in the house - this one operates independently. So I think I would actually prefer a wired alarm - with a 10 year battery backup. But this works as advertised - and is very simple - especially if it is new construction or an added detector. The detector includes the base plate, mounting screws and drywall anchors - everything you need. The battery is pre-installed, so you don't even need to do that. Very easy. June 2, 2015
Rated 4.0 out of 5.0 by these are the hardest reviews to write I mean, what do you say? "I really hope it never goes off for real, because that means something really bad is happening in my house."? Which, to be fair, is *exactly* what I hope (i.e. that it never has a good reason to go off for real). What I *can* say beyond that is that I really like the trend over the past couple of years of going to a 10 year sealed battery, as well as combining the smoke and CO functions into one alarm. As a homeowner and a landlord, I can tell you that keeping track of over a dozen different alarms on 4 different floors (some of which take 9V batteries, and some AA) can be a real pain. Especially when something starts chirping low battery in the middle of the night, and there's at least a couple of nearby alarms it could be. I've been transitioning mine over to sealed battery units as they start to die, so this unit fits perfectly with that pattern. One minor concern I'll mention is that when I tested it, while the beep was pretty loud, the spoken voice component (that tells you if it's detecting smoke or CO) didn't seem as loud. I suppose as long as something alerts you to a problem, you can pay more attention to the actual words. I only mention it because I purchased a different speaking alarm last year, and the spoken alert on that one was much louder. June 25, 2015
Rated 4.0 out of 5.0 by Simple install; long battery life This detector uses the same one as the other Worry Free units so if you're replacing one the install is as simple as removing the old detector and putting this one on the old mounting disc. If you have to install the kit comes with some wall anchors, screws, and a self-tapping center screw. To activate the alarm you simply spin it onto the mounting bracket. It will chirp and ask you to push the test button. Once the test is completed (its a little loud), the unit is armed and ready. I have this one in the kitchen and even with cooking it hasn't given me a false alarm yet. A drawback to this unit is you can't turn it off and on at will. I forgot to wrap my old one while a remodel was happening and it caused it to malfunction so I simply had to turn it off using the 1-time off toggle switch. The second drawback is the alarm during the test was loud and audible but the voice alert seemed muffled and soft. Ultimately, I don't have wired detectors and for the price and 10 year life span it is a good value. I've used Kidde products for 10+ years including fire extinguishers and found them to be high quality and reliable. June 11, 2015
Rated 5.0 out of 5.0 by Recommend this for everyone We literally plugged this in in just minutes, and have felt reassured ever since. CO2 poisoning is a problem with older furnaces and in many other situations, and we are happy to have this detector to add another layer of security in our home. The fact that one unit provides smoke and CO2 protection, with a voice warning, should we be sleeping, is just another reason we trust this detector. February 11, 2016
Rated 1.0 out of 5.0 by Did not last Combo Kidde smoke/CO detector lasted only 7 months. Kidde will not honor 10 year warranty without receipt. February 22, 2016
