This smoke & CO detector has enhanced sensing technology that reduces false alarms often caused by cooking and sends fast alerts that help give your family more time to get out safely. To detect carbon monoxide, an electrochemical sensor is used. This alarm offers a modern 5-inch design ideal for all living spaces such as living rooms, hallways, kitchens, & bedrooms. Voice alerts clearly announce “Fire!” or “Warning Carbon Monoxide!” to help identify which hazard is detected. Comprehensively tested and designed to the latest UL standard for safety and reliability, the 5-inch smoke & CO alarm is powered by 120V AC wiring with a 10-year built-in lithium battery, so you never have to change a battery for the life of the detector (not a battery performance claim). In addition, it’s self-testing and easy to install with the included twist-and-click mounting bracket. Meets requirements of 9th Edition UL 217, UL 2034 4th Edition, FCC, and CSFM.

Works as advertised.. the fact that no need to change battery for 10 years is great.. Keep in mind that interconnect is not compatible with all brands.. always replace them with same brand to make sure when time counts they are all working. This model has a voice feature which is great instead annoying beep..

I installed 5 of these in my home to replace the old battery smoke detectors and they work great. They come with are different connector, so you have to. get an electrician or turn of the fuse if you have the skills to replace the electrical pigtail (wires) yourself. I would have done it myself but my wife wont let me climb a ladder anymore. Fast install and they work great, connected to my current security system and with a 10 year battery, I will no longer have to get up a 2 AM and try to find and replace the stupid battery. I just ordered 5 more to completely replace all of the old smoke detectors and add a new one to the garage where I charge my car at night. Great product. A little expensive, but you are getting carbon monoxide detection where I only had smoke detectors before and worth every penny, knowing I will not have to deal with them for 10 years.

I got these to replace expired 10 year old Kidde hardwired/battery alarms which had started chirping at random hours. The manufacture date on these new ones was only 6 months old. The alarms came in brown boxes (not the original looking Kidde boxes you see on the web site) with a Kidde label, wiring harness, alarm with base plate,a red dust cover, instructions, but no mounting screws.The first alarm I screwed together , it activated with a chirp, but then I could not unscrew it to make a wire harness adjustment. This would have been a disaster had it been firmly attached to the ceiling. I thought this might be a one off. The second unit, I could not get it to screw to the base. The battery screw on this second unit was pointing towards the on position out of the box, but pushing the test button did not elicit a beep or voice message. I opened a third unit and it did not screw easily onto the base and I decided to return them. There appeared to be some superficial damage in the center of the label on two of the units. I could not figure out why these units would not unscrew from the base or screw onto the base. The existing old Kidde alarms in my house easily unscrewed from the base. The old base can not be reused; it is the same diameter, but different structurally from the new base.I will probably try to find the new alarm in theoriginal Kidde packaging-other reviewers here are not reporting this problem.By the way, separately I recently reviewed the similar Kidde 10 year battery smoke carbon monoxide alarm-not hardwired-and the alarm screwed easily to the base plate with no installation problems; these came in original Kidde packaging with anchor screws and red dust covers.

Great item which was easy to install. Very easy to unhook the wiring from the old smoke detector and hook up the new ones. The mounting plate fit easily right on the old detectors mounting holes. Installed the new one in less than fifteen minutes. I like the fact that it tells you if is detecting smoke or carbon monoxide.

I purchased 4 to replace older smoke only detectors. Co2 is required by code, here, and it's good prevention anyway to upgrade if you have smoke only. I replaced one right near the heating equipment and we got an alarm the first night but I cleare it and it's been fine since. The others are in bedroms and a hallway on te 2nd floor.

These interconnected with my Kidde smart unit with IAQ perfectly. If one of these detects CO, the WiFi unit will alert me that it's CO, even though the detection was from one of these non-WiFi alarms. Easy install and look good

Was a replacement for an older model. Super easy to install and snapped into my existing mount. Pleased that this company continues to use the same mount and makes connection adapters. Easy for consumers and appreciate the quality and functionality!

I was sick of my alkaline battery Kidde units chirping every year, invariably when I was traveling. My wife HATED that. These new Kidde are powered units with lithium battery backup. Still, I had to replace the wiring harness becuase they didn't match the old units. It was all pretty easy. Also, I feel like they are less prone to false alarms. The one near the kitchen used to go off frequently. The new one has not sounded once during cooking.
