## Description

desertcart.com Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air. The First Alert CO600 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. The test/silence button both silences a non-threatening alarm and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. UL listed.--Bree NorlanderWhat's in the Box One carbon monoxide alarm and user's manual Product Description The First Alert CO600 Plug In Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor to detect carbon monoxide. The plug in design of this personal carbon monoxide detector means you can simply plug the alarm into a 120 volt wall outlet, and the carbon monoxide detector is ready to go. When CO levels become elevated, a loud 85 decibel alarm alerts you to the threat. Designed to be simple to use, the CO detector has just 1 button that silences or tests the unit, as well as an end of life timer that lets you know when it is time to replace the device.

Review: Good Alarm - Since most of the major appliances, stove, heater, water heater etc in my home are powered by natural gas I decided CO alarms would be a good Idea. This alarm has a small form factor so it does not take up all the space of the electric socket, you will still be able to use the top plug. Its a plug and play application. Plug it in run the test and you are good to go. Although small the alarm has a loud warning alarm in case CO is detected. I haven't experienced any false alarms or weird behavior from the alarm and so far is has worked well. The US Consumer Product Safety Commission recommends buying and installing a CO alarm that meets the requirements of the current UL 2034 safety standard. I saw a review here stating that this alarm was not UL 2034 certified, which is not true. The CO600 is UL2034 certified. Underwriters Laboratories Inc. UL2034 defines three specific alarm points by which all residential CO alarms must alarm. They are measured in parts per million (ppm) of CO over time (in minutes). UL2034 Required Alarm Points: * If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES. * If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES. * If the alarm is exposed to 70 ppm of CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES. The detector must ignore CO levels of 30 ppm or less for at least 30 days and ingore levels of 70 ppm or less for at least an hour. There are detectors available that will alarm at a lower level. All detectors must have a silence button. Pushing it will silence the alarm for four to six minutes. If the concentrations stay above 70 PPM it will alarm again in six minutes. (Previously set at 100 PPM) The detectors have only two alarms, a full alarm and a trouble alarm. The second revision of UL-2034 detectors allowed (not mandated) warning alarms that sounded at low levels. Some found this confusing. Detectors manufactured under the new standard should reduce the number of nuisance alarms. These detectors must not alarm in the presence of the gases listed in the following table below the indicated level. Methane 500 PPM Butane 300 PPM Heptane 500 PPM Ethyl Acetate 200 PPM Isopropyl Alcohol 200 PPM Carbon Dioxide (CO2) 5,000 PPM More info on UL-2034 can be found on Underwriters Laboratories website ul.com If the device starts to malfunction/ give false alarms I will update my review.
Review: Accurate and dependable - I ordered this as a replacement for the exact same product. It produced the ‘end of life’ warning seven years after installation almost to the day. I never had an issue with false readings, and when I had my furnace serviced, I had the tech check for built up fumes to see if the sensor had missed a build up, and it was not misreading. The plug in feature is great…no need to replace batteries!

### ⭐⭐⭐⭐⭐ good purchase
*by K***Y on February 5, 2026*

Easy to plug in and good to have the peace of mind knowing it’s there. Our previous alarm got to end of life and started beeping - I would appreciate a little more clarity which beeps are end of life and which beeps are the alarm!
