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.
Kidde’s KN-COPP-LPM battery-operated carbon monoxide alarm with digital display helps to provide your home with extensive protection against the dangerous threat posed by the odorless and colorless gas. With an increasing number of state and local governments passing legislation requiring CO detectors in homes, it’s never been a better time to safeguard your family against carbon monoxide exposure.
Kidde's KN-COPP-LPM carbon monoxide detector is a free-standing unit, adding flexibility to placement around your home. View larger
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.

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. If you press the "peak level" button, though, it will tell you what its peak reading was even if it was below 30 ppm. This works down to the 10-15 ppm range, below which you don't really have to worry about CO at all. Prolonged exposure around 50 ppm leads to an alarm after a couple of hours.
Another, simpler test (which anyone with a CO detector should do to make sure it's working) is to light a candle in an enclosed container with the CO detector, then close the container. The candle will burn through the available oxygen and a fair amount of incomplete combustion (releasing CO instead of CO2) will occur as it runs out of O2. I tried this and got 96 ppm with a small candle in my gallon container; a larger candle would probably release more. I then tried it by lighting a crumpled piece of newspaper in the container and got >910 ppm, which is reasonable because paper and wood experience pyrolysis, which releases lots of CO. Combustion of small amounts of acetone (a fairly clean fuel relative to paper) resulted in 300-550 ppm depending on how hot the fire got before I put the lid on; the lower reading relative to paper helps confirm that it's reading accurately.
In conclusion - this $20 detector works very well when tested with real CO. It's accurate, the alarm goes off at dangerous CO levels, it only goes off if CO levels are dangerous, and it might just save your life.
- Battery operated with three AA batteries included!!
- Easy to read large medium display even in low light conditions
- Designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million of CO)
- 5 to 7 year End of Life
- None so far
Overall i like this unit much better than my old one because the older unit only had a LED blinking letting me that there was CO present or the batteries were dying.
I was woken up at 4 am by my old CO alarm beeping constantly, after checking the unit it only had a blinking LED to tell me that 5 blinks meant the unit was at the end of life! I was scared and decided to open all windows and doors anyway having family over i stayed up until everyone was up.
I suggest you getting few of this just in case depending how big is your place and always have an extra one sealed in case they go off!!!
Amazon has the lowest price for this unit so i got an extra one! :-)
