The Kidde KN-COPP-B-LPM battery operated CO alarm provides continuous monitoring of CO levels, even during power outages when many CO incidents occur. The digital display feature allows for easy viewing of carbon monoxide levels from 30-999 PPM (parts per million). The KN-COPP-B-LPM will also detect and store concentration CO levels as low as 11 and up to 999 PPM with its peak level memory display. This alarm includes a slide-out battery door that gives immediate access to the batteries and a safety feature that makes it difficult to close the cover without the batteries being installed. It has a 10-year life and a 10-year limited warranty.

    Seems like a really good CO monitor for the money

    This CO monitor is nice in that it has a readout of CO level in parts per million (PPM) instead of only alarming after CO is detected for the requisite time per UL standard 2034, so if you are curious you can look at the display and see if even trace amounts of CO are indicated (except that display indicates "0" until at least 30PPM have been detected). Also, if you press and hold the Peak Level button, the display will indicate the highest CO level that has been detected since batteries were last changed or the unit was last reset using the Test/Rest button. When you first put batteries in, the unit alarms for about a second, and it seems dang loud to me (of course I'm holding it in my hands at that point rather than standing across the room or in another room). When the batteries need to be changed, the unit indicates "Lb" in the display and chirps every 60 seconds (like a smoke detector). The unit can either be mounted on the wall or placed on a flat surface (I'm using it that way on my desk at work). One reviewer said that this CO monitor does not have a display; I'm quite certain that that is incorrect. Perhaps an incorrect CO monitor was shipped to that reviewer. The unit I have is Model Number KN-COPP-B-LPM (Part Number 900-0146-LP) - this information is taken from a sticker inside the battery compartment. Note, though, that the packaging for my CO monitor omits the "-B" from the middle of the Model Number. See pictures attached to this review showing the CO monitor unit and the label inside the battery compartment.

    Seems to work well

    I recently had another Kidde CO detector hit its end of life, which it did signal, so wanted to buy a new one before turning on my furnace. I wanted a battery operated detector because my older house has precious few free outlets and this gives me much more freedom in placement. I also wanted one with a digital display because there is something reassuring about seeing it actually say zero. It was easy to set up, even for me - a person who winces while putting batteries into alarms, anticipating I'll set it off. It did make one sharp beep as I placed the final battery, but that is all. As someone else mentioned, it is (currently) less expensive on the Walmart site. I picked one up in the store, but it was more at the checkout and for whatever reason, they won't price match themselves! So I placed the order on my phone and picked it up a few hours later (probably even the same unit I'd had in my hand).

    Saved My Life

    I bought two of these and put them in my bedroom and living room. After almost two years of trouble free operation my alarm sounded in my living room at 41PPM. I later found out that the tankless water heater all the way across my house was putting out deadly CO and it had made its way to my living room across my house. I moved one of the detectors into the room where the CO was putting out. The levels got up to 249 before the fresh air took over and the levels came down. These detectors work. To measure levels below 30PPM just hit the peak level button to see if any CO levels below 30 have been picked up by your detector.

    meets expectations

    product has some nice features such as an 'End of Life' indicator and battery indicator. It also uses the LCD to display current CO2 levels inside the home. upon opening the original packaging I found that one of the CO detectors had a battery terminal that was damaged. after a simple repair both the CO detectors worked perfectly. The reason I marked 'meets expectations' as only 4 stars not 5 is that I shouldn't have had to repair a brand new product to make it functional.

    It's A Good Secondary Alarm

    Once I got it working, I looked through the manual and discovered it would take 60 to 120 min to sound an alarm once it detected Carbon Monoxide between 70ppm and 150ppm. I do not recommend this being the main CO alarm in the house, but I do recommend one of these in every bedroom to be used as a secondary alarm, just in case the primary alarms are offline. For the one I have, I checked its Peak Level right after I got it out of the package and discovered it had detected CO in the past at around 11ppm. This may be a sign that they actually test these in real world scenarios before they sell them, but it could be programmed in just to make it convincing. Either way, it should be reliable due to its UL rating. It'll do its job if you keep it maintain and it should pay off in the end.

    Much better value than the unit I replaced.

    This unit has more features and is longer lasting than the old Kidde Unit it replaced. My only question is why dosen't Kiddie Standardize the spread of the mounting holes? I had to drill another hole for this unit.

    good product for CO detection.

    Easy to install and setup. I have one on each level of home.

    Great for Travel

    Purchased this to use in hotel rooms as we travel. Need to be proactive for ourselves. Battery operated and small size, perfect solution.

    Peace of mind plus

    I own a gas furnace and water heater. As such, a Co2 detector is a must have. This has exactly the right features I wanted and need. The digital read out will warn you before an issue with your systems reach a critical concern. The audible alarm is great in that it is really, really loud. No chance of possibly sleeping through that! Mounting location is critical. As per advised, I mounted mine close to a vent in the bedrooms. Installation was a snap using 3D removable strips thus eliminating the need for new holes in the wall. I bought mine with free shipping to store and the process was simple. Stay safe my friends!

    Digital Kidde Battery Powered CO Alarm

    I cannot speak to the intended functionality (detection of CO) of this device since it has not detected any CO and there likely hasn't been any for it to detect. Otherwise, it set up properly when the included batteries were installed. It will stand up on a flat surface by itself, or it can be attached to a wall using the two screw slots. One of these replaced a previous Kidde CO detector that was wall mounted; I wish Kidde would standardize the distance between the mounting holes -- I had to drill another hole in the wall since I could not use the existing screws owing to their not being the proper distance apart for the new device.
