Features
The KN-COPP-LPM is an essential device to help warn you and your family of dangerous carbon monoxide levels in your home. This alarm measures the exposure to carbon monoxide over time; it is designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million) of CO for 60 to 240 minutes, 150 ppm for 10 to 50 minutes, or 400 ppm for 4 to 15 minutes. The easily visible digital display indicates the level of CO that the unit is sensing, and it updates the status every 15 seconds for timely and accurate readings. Its free-standing design allows for attachment to a wall or placement on a counter or nightstand for convenient and comprehensive protection. The KN-COPP-LPM also includes a slide-out battery door that provides immediate access to the power source as well as a battery safeguard that makes it difficult to close the cover without batteries installed. An LED lighting system on the unit signals power levels and sourcing: the green LED will flash once every 30 seconds to indicate the alarm is operating properly when power is present, and the red LED will pulse to indicate carbon monoxide has been detected until the device is reset or the CO threat is eliminated. This device has an expected 7-year lifespan and comes equipped with a five-year manufacturer’s limited warranty.

With emergency products like CO detectors, it's hard to know if they really work unless you're actually being exposed to dangerous amounts of CO. And if a CO detector doesn't work, you wouldn't know; instead, you'd just be poisoned while thinking that nothing was wrong. The only way to really find out if it works is to put it in an airtight container and generate CO.

Because I like to play with dangerous chemicals at home, I decided to try this out. Adding formic acid to concentrated sulfuric acid causes the formic acid (HCOOH) to break down into CO and H2O. I got both of these chemicals for less than $10/liter apiece, plus shipping. I put some sulfuric acid into a graduated cylinder and placed it in a 1-gallon airtight plastic container. I then added small amounts of diluted formic acid and rapidly closed the container.

Sure enough, it worked! It registered CO concentrations that were well within the ballpark of what I'd expect to get with the amount of formic acid I added (using the ideal gas law to figure out what the maximum CO level would be). In high concentration tests, I found that the alarm goes off within 3 minutes of hitting 500 ppm (which is dangerous but would take several hours to kill, giving plenty of time to get to fresh air). In another test, it went off after about 20 minutes of CO levels around 190 ppm, which is dangerous but not lethal. Its peak reading is in the 910-920 ppm range; it doesn't display levels higher than that. Needless to say, it goes off within a minute or two of such high CO levels and anybody who sees 900+ ppm on the display should leave their house and seek medical help immediately.

It worked well in low concentration tests too. Due to some strange US regulation, it displays "0" for any reading below 30 ppm.

I did a lot of reading on all the different type of CO1 detectors offered here on Amazon. I chose this model not only for my own home, but also for the customers I install CO1 units into their homes (I'm a contractor). This is not the cheapest model available and the same company makes one without the digital readout which is less expensive, but I believe it's worth the extra money to have the readout. That way, I feel that if there is a problem, it may be caught sooner than later if the amount of emissions are listed. This unit is guaranteed to last seven years as opposed to the other model without the readout at five years. It's one place I would not want to cut corners. I also prefer the types that are mounted at eye level and not into an outlet.

I don't have a lot of experience with CO alarms, but my previous one was a Nighthawk model that was considerably bigger that lasted 7 years from date of Manufacture, but I think it was 1/2 that since I had it installed. When it died it displayed "Err" and beeped periodically. It was required to be plugged in with an adapter, and used a 9V Battery backup.

I bought two of these Kidde KM-COPP-B-LPM models as replacements so I could have one on each level. I wanted a battery only operated one so I would have more flexibility in placement of the device, and so it was easier to monitor without messy cords.

Installation was easy, but it would have been nice if they had mentioned a suitable drill-bit size for the plastic anchors to be inserted, not a big deal but they should have done it for the less experienced. On the positive side at least they privided anchors with the screws.

I was most pleasantly surprised with its compact size (uploaded image of it above light-switch panel). The instructions were fairly detailed and easy to read. I like that the unit has a internal timer and after 7 years will let you know it is time to replace unit. I'm a bit confused though because information on the packaging says the End-of-Life appears after 7 years, but a sticker on the unit says it shuts down after 10 years, I believe the instructions talk about the EOL indicator, but never mention a timeframe.

Overall this device was what I was looking for and Amazon offered a 15% discount if you purchased more then 1 unit so that worked out well too. Now I just have to hope for 5 years or more of problem free operation.

I ordered this to verify one (another brand CO detector with meter) I've had went off several weeks ago. The one that I had in the house for more than three years went off and showed around 40 PPM. Since it was over three years old, I thought that it was possibly bad. So I went to Wallmart and bought a cheap CO detector without a meter. I thought I was safe, because the new one never went off. Then I read that it will not alarm until it gets to 50 PPM. I decided to buy this Kidde CO meter. My old CO detector went off again and showed about 30 PPM this time (not as cold outside during this day). I looked at the Kidde and it showed 20PPM (the Kidde alarm did not sound an alarm though). I called 911 and the firemen came to my house and took readings with their meter and showed 19 PPM. They turned off my furnace and the gas. The gas company determined that my forced air gas furnace was blowing CO throughout the house, because the furnace heat ex-changer had holes in it. They said that CO builds up in your body and is potently lethal. I actually feel physically much better now that my furnace is fixed. Sure glad I got the CO detectors WITH a meter.
