## Description

Product Description The Kidde Carbon Monoxide Detector, Plug In Wall with 9-Volt Battery Backup, Digital LED Display uses electrochemical sensor technology to detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm. Setup is easy as the Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet in your home, while a 9-volt alkaline battery (included) works as a backup in the event of a power failure. When carbon monoxide is detected, the digital display shows the level of carbon monoxide the alarm is sensing and updates every 15 seconds. Peak Level Memory records the last time carbon monoxide was detected or when the unit was tested. 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. Extension cord (included) allows for placement on a table or shelf. 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). From the Manufacturer The leading cause of accidental poisoning deaths in North America, Carbon Monoxide is odorless, tasteless and invisible, it's a silent killer. Kidde CO alarms include the most accurate sensing technology available, the patented Nighthawk electrochemical sensor. This alarm can be mounted three ways: plug directly into AC receptacle, mount on tabletop using 8 foot power cord, or wall-mount. The digital readout continuously displays carbon monoxide levels from 30-999 parts per million. This unit has a loud, 85-decibel alarm that sounds when CO reaches dangerous levels. One of the features of this product is peak level memory, which means this unit will recall highest level of CO present since previous reset. Install at least one CO alarm on every floor and in sleeping areas. Make sure CO alarms are at least 15 feet away from cooking or heating appliances to prevent false alarms. Replace CO alarms every 5 to 7 years to benefit from the latest technology upgrades.

Review: Inexpensive insurance. - I have a number of these throughout our house. They have worked flawlessly. They alerted once when a carpet cleaner turned on his generator while his vehicle was inside our garage. Numbers were high enough that the fire department ventilated our house. Could have been a disaster had they not alerted us. This purchase replaced a similar one that failed after many years. Made in Mexico now, but I expect the same performance. Battery backup is important to me as we experience frequent power failures.
Review: Carbon Monoxide Protection for your Home - I purchased the Kidde Carbon Monoxide Detector for my home to replace another unit that had expired. The Kidde Detector plug-in design with a 9-volt battery backup is very convenient & easy to use. It offers continuous protection even during power outages. The digital LED display clearly shows CO levels, which is helpful for peace of mind. Unit came ready to use, with battery already installed. We just pluged it in and it was ready to use. We feel confident that our family has chosen a great carbon monoxide detector for our home.

## Questions & Answers

**Q: what is the manufacture date on this? I see a lot of reviews showing old out of date units received.**
A: Ordered in January 2017.  Date of manufacture: October 2003.  People must be careful when ordering these, especially from third party sellers.  I bought one from a third party seller for a ridiculously low price -- big mistake, as the unit was over 13 years old!  (Note: The date of manufacture is on a label on the BACK of the unit, which is not visible when the unit is encased in its original packaging.  There is no way to know the date of manufacture unless you physically remove the unit from its hermetically sealed packaging and examine the label on the back of the unit.)

**Q: Can the alarm funtion be disabled? i want to use in a space where i want higher than normal levels of co2.**
A: Do NOT simply clip one wire to the transducer as in a smarter device a monitoring voltage may discover the alarm is disabled and disarm the monitor entirely. Depending on construction, you also should not remove any coating from a pcb and unsolder the correct terminal. That would probably break the alsrm and a federal statute.

**Q: The Kiddi web site says this has a 10 year life and 10 year warranty for this model900-0076. Are these old ones that your selling?**
A: My old one lasted 7years 5 days 36 minutes.  I just put the new models in and they work fine.  As far as how long they warranty 10 years.

**Q: Can someone explain how to insert the battery?**
A: Remove unit from packaging and turn unit so the AC power connector is facing you.  There is a U shaped section around the AC connector with a series of dashes on both upright section.  Push both of those towards the opposite end of the unit. This will unlock the U shaped cover.  Remove the cover.   My unit came with mounting screws and a drier pack that where inside the battery compartment.  The connector for the battery is visible after removing the items in the compartment.  Connect the battery and install the back cover, you are good to go!

### ⭐⭐⭐⭐⭐ Quality CO detector. Worthwhile investment.
*by A***J on April 28, 2024*

Quality Kidde brand CO detector. I replaced my original one with this identical one after 10 years of service, when it finally beeped and showed "END" in the display, which renders it useless, which is by design. Ironically, I never had any CO issues or alerts, until about a few months before its 10th anniversary in service. My home's natural gas boiler was over 25 years old, and begin leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded. Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detectors audible & visual alerts. Hope they're still making this model 10 years from now, when I will need another one, or if I decide to move and want to purchase a new one. It's certainly not the cheapest CO unit on the market, but it's a good value for the money. Oh, it plugs directly into any standard 110-volt power outlet and it has a 9-volt battery backup, battery included. Although they recommend you replace the 9V backup battery every few years, I never replaced mine, and it was still almost as good as the day it was installed. My Kidde CO detector is plugged into an outlet in our upstairs hallway just outside of our bedroom. Fortunately, it also fit perfectly next to (below) my plug-in doorbell, which was a huge plus! I'm planning on installing one in the basement, near the gas boiler as well. Should have done that years ago, as we would have likely received an earlier "heads-up" that there was a combustion problem with the boiler. One last note: You can remote wall-mount this unit also. Cool feature! If you look at the last picture that I posted with this review, you can see that when the rear access cover is removed to access the backup battery, there is extra cord stored on the opposite side of the battery. The connected main power source plug can be easily removed and relocated/extended, via the corded connection, in order to have the CO detector located somewhere other than directly plugged into the power source. There is also a handy little clear plastic packet included, containing two wood/mounting screws and two wall mount plastic expanding inserts. (Not shown in picture.) Just can't say enough good stuff about this unit. Very pleased with it!
