Kidde Worry-Free Digital Carbon Monoxide Alarm

Kidde Worry-Free carbon monoxide (CO) alarms offer 10 years of continuous detection from the leading cause of accidental poisoning deaths in America – carbon monoxide. The UL-listed alarms are the first and only models to contain a 10-year sensor as well as a sealed-in lithium battery proven to power the alarm for a decade. These two state-of-the-art technologies combine to create a premier level of protection. Digital Display Screen clearly shows the level of CO in that room and updates the reading every 15 seconds. Homeowners have peace of mind knowing their CO alarm is always on, and they never have to be hassled by low-battery chirps or battery replacement. Until now, a CO sensor operated for five to seven years, based on the manufacturer. The Worry-Free alarms last nearly twice as long as the average model.

Long-Life Sealed Lithium Battery: Why It’s Needed

Each year, fire departments respond to an average of 72,000 CO poisoning incidents, according to the National Fire Protection Association. Known as the ‘silent killer,’ carbon monoxide is odorless, tasteless and invisible. The only safe way to detect it is with a working CO alarm. Industry surveys find approximately half of U.S. homes have a carbon monoxide alarm installed, most of those are battery-operated. A recent survey conducted on behalf of Kidde found homeowners’ number one fire safety complaint is a low battery chirp.

Worry Free Benefits

The C3010D carbon monoxide detection unit provides one decade of protection; the sealed lithium batter provides 10 years of continuous power. It is also both maintenance-free and hassle-free; never replace a battery during the alarm’s operating life and no need to worry about the batteries being removed. Additionally, this Worry Free unit is the longest sensor life available and is proven effective for ten years with quick and easy installation by simply sliding the alarm onto the mounted bracket which activates it automatically. Money savings: no batteries to buy and replace every six months, save up to $40 over the life of the alarm.

What's in the box

One single Kidde Worry-Free Digital Carbon Monoxide Alarm. A ten-year limited warranty.

Specifications

  • Digital Display Screen clearly shows the level of CO in that room and updates the reading every 15 seconds
  • UL Listed – tested by an independent nonprofit testing agency to ensure it meets the US standard
  • 85 decibel alarm – loud enough to wake the average sleeping adult
  • Nighthawk electro-chemical sensor, which is proven to be the world’s most accurate based on claims by major manufacturers
  • Test-Reset Button tests the alarm circuitry and horn, resets memory after alarm has sounded
  • End-of-life signal chirps every 30-45 seconds when alarm needs to be replaced – approximately 10 years after power
  • Deactivation switch disables the alarm and makes the batteries safe for disposal once the unit has reached the end of its 10-year life
  • Tamper resistant feature prohibits a disabled alarm from being placed back onto the mounting bracket
  • 10-Year Limited Warranty lasts the life of the alarm

Did the candle test - CO sensors Work!

Did the candle test - CO sensors Work!
Just got this today but so far, so good! The CO sensor definitely works, as I did a little test. I’ve been suspecting there might be low levels of CO in my apt coming from the heating system in my building. I am hoping I am wrong but nonetheless decided to get a CO detector with a digital display so I can monitor.Reviews on the model seemed good and I wanted one that is battery powered and portable to be placed anywhere. I wasn’t sure about the lithium batteries but the ones with replaceable batteries are out of stock so I went with this one.Opened package, (mfg date 2/2108, not bad but not great since it’s already Dec 2018.), activated it and all worked properly, display at zero.I wanted to be ABSOLUTELY CERTAIN the CO sensors were working properly so I did the candle test. I placed the unit in a stainless steel kitchen pot along with a lighted tea candle. Placed a pan over the lid to create an air tight environment. And waited about 3-4minutes. When I opened it back up the sensor was reading 90. Over the next 2-3 minutes, it rapidly went back down to 0. After it went back down to 0, I pressed the peak level button and it showed 90.So now I feel confident that this unit does what it’s meant to do. I can’t speak yet to battery life since I just got it.This is great because the digital display is constant and can be seen at all times.Highly recommend getting one of these for every bedroom in your house and placing it next to your bedside.

5.0 out of 5 stars Best Carbon Monoxide Detector on the Market
Reviewed in Canada on December 25, 2019
I did not get paid or receive anything for my review. I personally ordered and paid for this item at Amazon.ca: Verified Purchase.

I have owned several of the Kidde ( pronounced KID-AH ) larger plug in type Carbon Monoxide detectors ( square and with a 9 Volt backup- approximately $70. ) and as they state you will get approximately 7 years before they start to chirp every 30 seconds indicating that the unit needs to be replaced. For less than $50. though you can buy this model and its totally 100% portable and can be placed anywhere in your home ( on a shelf or out of sight ) and it will last 10 years with its sealed 10 year lithium battery. To me that is a better buy at less than $50. There is no green light that stays on permanently as indicated in the advertisement photos. The green light in the top centre position only flashes every 30 seconds and the numerical screen in the centre of the unit never lights up but does display LED numbers. The wall bracket is simply taped to the back of the unit when it arrives. You must slide this wall bracket plate into the unit ( from the bottom up - slots on both sides ) in order to power the unit on. I hope you enjoyed my review and it was helpful.
