Features

  • 2-in-1 Detection - Smoke & carbon monoxide detector combo alerts you to both smoke & fire events as well as poisonous, CO gas in a single device
  • Photoelectric sensor detects visible fire particles associated with slow, smoldering fires, while the electrochemical sensor detects carbon monoxide
  • An 85-decibel alarm sounds & a red LED indicates the smoke detector is sensing smoke or fire
  • Lithium battery operated: eliminates the need for battery replacement & provides reliable detection, even during power outages
  • Test-Hush button makes it easy to test the smoke detector and silence false alarms that occur from cooking or shower steam
  • The alarm will automatically activate when it is attached to the mounting bracket, there are no pull tabs, no switches, everything is automatic
  • At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement
  • UL listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim). Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that replacement is needed.

Description

The Kidde Smoke Detector & Carbon Monoxide Detector Combo with 10-Year Battery, model P3010K-CO, provides two fire safety detectors in one unit through the use of photoelectric sensing technology that senses visible fire particles, while an electrochemical sensor detects carbon monoxide. When a smoke, fire, or carbon monoxide event occurs, the Kidde fire alarm warns with an 85-decibel alarm sound & a flashing LED. The Kidde combination smoke and carbon monoxide alarm is powered by a 10-year lithium battery, which eliminates the need for battery replacement while providing coverage during a power failure. In the case of a nuisance or a false alarm, the Smart-Hush button silences the unit for approximately 8 minutes, which is helpful when this smoke detector carbon monoxide detector combo sounds from things like routine cooking or shower steam. When installed, the green LED on the alarm will flash every 60 seconds in standby condition, letting you know that the unit has power & is operating correctly. Install a carbon monoxide smoke detector combo on every level of your home and near bedrooms to help keep your family safe. UL Certified with a 10-year limited manufacturer's warranty. Meets requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD).

  • Good deal product and easy installation
Size: 1 Pack Pattern Name: 30CUD10
Easy installation, we tested the product and it seemed to work well. The price was excellent, it was a better deal than purchasing it at the store. It only took a minute to put up. I love the fact that the battery does not have to be replaced and hopefully will last 10 years as promised.

  • What's to not like
Size: 1 Pack Pattern Name: 30CUD10
I've had this very model detector in my house for 12 years and it finally gave out so I feel like 12 years is a pretty good lifespan so I just bought another one!

  • Works perfectly

Fits on previous model base. Took less than a minute to install. It’s worth the money

  • Good quality smoke and CO2 detector but I wish they would standardize brackets
Size: 1 Pack Pattern Name: 30CUD10
The time finally came. Our smoke and carbon monoxide detector (also a Kidde brand) from 2010 finally died and we needed a replacement and the unholy chirp constantly reminded us. After reading various reviews from various online sources, we settled on this newer Kidde smoke and carbon monoxide detector with a sealed 10 year battery. The detector itself was easy enough to install with the included bracket but my biggest gripe is that there is no bracket standard, not just between brands but within the same brand. So to install the new bracket I had to pluck the old wall anchors out and drill new holes for new anchors because the hole pattern was different. Very frustrating because a standard set of hole patterns would allow you to utilize the old anchor points, saving time. I'm too lazy to fill and repaint all the holes so the detector is covering up decades of various bracket holes. Positives + Sealed unit with 10 year life so no battery replacements + Easy enough to install + Easy to test and see function by color coded LEDs + Detects both smoke and carbon monoxide Negatives - No bracket standard hole pattern means having to drill new holes and possibly remove old anchors ... show more

  • Worth the money
Size: 1 Pack Pattern Name: 30CUD10
Love these. Worth the money if you have gas fixtures. One important feature is that they are all linked. If one goes off in the house it signals the others to go off. I love it because if there were a fire or carbon monoxide leak on one floor of my house, everyone at home would be alerted. They are super sensitive to smoke, mine have gone off a few times when I was cooking. Referencing my above comment, this was super annoying to everyone else in the house because all the alarms were going off as well. ... show more

  • Tricky to activate
Size: 1 Pack Pattern Name: 30CUD10
I gave this 4 stars because to me it was tricky to know if activated. I read negative reviews and learned from others what not to do which was a big help. I felt it really should get 3 stars for the difficulty to activate though. So...my detector has a red activator switch you turn clockwise to activate. If you turn it counterclockwise; your done and it's dead you just killed it and there's no turning back; you will need a new one. Once activated you can press to test/silence button to test. I had difficulty with this because the light turned amber, flashed and alarmed and didn't stop when I released the button. Finally I got it to settle down but wasn't sure if it was really active because no light at all illuminated. On most detectors the light is green to let you know it is working/active. Not on this model. After looking at it for what seemed like an eternity, it finally blinked green. Make sure the button is depressed and not raised as it is when removed from packaging. Depressed button is activated. You will just need to look at it for a minute to make sure it blinks green. Maybe it doesn't stay illuminated to save battery life I dunno but for a safety product it needs to be simpler for the consumer to operate/activate with out a doubt to know the product is functioning as it should. For this reason I felt it should be 3 stars but gave 4 because I assume it's working properly. It wasn't the easiest to operate/activate and I don't understand why it just couldn't have a pull tab to activate the battery/detector. I recommend this if you are unable to find a more user friendly brand that functions as both C02 & smoke detector; otherwise I don't recommend due to this not being as user friendly as I feel if could/should be. ... show more
