Description

The Kidde Carbon Monoxide Detector, AA Battery Powered CO Alarm with LEDs, model 900-0146, is a carbon monoxide detector that uses electrochemical sensor technology to detect carbon monoxide. The CO detector is powered by 2-AA alkaline batteries located in the back of the unit, providing easy installation & no wiring, plus coverage during a power failure. The alarm is conveniently designed and portable enough for travel - simply install it on a wall or place it on a tabletop. When carbon monoxide is detected, an 85-decibel alarm will sound & a red LED will flash. A green LED indicates that the alarm is receiving power. The test-hush button allows you to test the battery operations as well as temporarily silence the low battery chirp warning. Plus, peak level memory records the last time carbon monoxide was detected or when the unit was last tested. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Certified with a 10-year limited manufacturer's 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. KN-COPP-LPM Battery-Operated Carbon Monoxide Alarm At a Glance:Digital display allows for easy monitoring of CO levels Battery operation provides best protection during power outages Peak level memory displays the highest CO concentration since last reset Dimensions: 4.5 inches by 2.75 inches by 1.5 inches; weighs .66 pounds with batteries Five-year limited warranty Kidde's KN-COPP-LPM carbon monoxide detector is a free-standing unit, adding flexibility to placement around your home. View larger 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. What's in the Box One Kidde KN-COPP-LPM battery-operated carbon monoxide alarm with digital display and three AA batteries. The KN-COPP-LPM features an easy-to-read digital display in front and an easy-access door to the batteries in back.

This key feature adds an advanced level of protection that you have come to expect in a Kidde manufactured product. The battery operated CO alarm includes multiple mounting options, allowing installation on a wall or tabletop. This alarm has been carefully designed and tested to detect CO concentration in a residential environment. It 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-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 snap-on cover that gives immediate access to the batteries and a safety feature that makes it difficult to close the cover without the batteries being installed. Updates digital reading every 15 seconds, allowing you to see if levels change. The peak level memory displays the highest CO concentration measured since the last reset. The test/reset button tests CO alarm circuit operation and allows you to immediately silence the alarm. A low battery signal alerts users when the batteries need to be replaced. Includes informative LEDs: green LED for normal operation, red LED for alarm. The alarm alerts user to replace CO alarm after 7 years of operation.Sensor: Electrochemical. See more

  • Works Well, But Read the Fine Print!
Size: KN-COPP-B-LPM Color: Detector Pattern Name: Detector
Attractive; Easy to Activate; Detects and Alarms Appropriately. I always read the 1 star reviews before buying a product. Some disturbing comments were: "batteries are impossible to insert" -- I had no trouble inserting the batteries (fit firmly but install with gentle pressure); "Tested with CO and got NO Audible Alarm" -- this was a big red flag, so I tested my unit upon activation. At 500+ ppm CO got good LED visible readout, but NO audible alarm. Was ready to repackage and return, but re-read the product information sheet: "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." I retested, exposing unit to 400-650 ppm CO and got an audible alarm at around 6 minutes. Removal from source, display returned to zero and audible alarm ceased. Much more assured that the unit works properly. And Audible Alarm times are well within guidelines for exposure to CO and symptom development (see photo). Also really like that I can replace batteries. Previous units with sealed batteries didn't last anywhere near the 10 year "useable life" advertised. ... show more

  • Tested with CO in closed container at varying concentrations. Worked very well!
Size: KN-COPP-B-LPM Color: Detector Pattern Name: Detector
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. 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. ... show more

  • Inexpensive and quick to alert.
Size: KN-COPP-B-LPM Color: Detector Pattern Name: Detector
We had a CO alarm go off in our house while running a generator outside but it did not have a display so we could not tell how high the concentration was. I ordered this and a couple of other CO monitors from Amazon and compared them. The 3 monitors tested were: 1) AS8700A handheld - designed for house inspection, not for continuous monitoring - range 0-1000ppm, 1ppm resolution - can display peak level since last reset - tests continuously, alerts within 5 seconds - adjustable alert level preset to 24ppm - measures ambient temperature - I paid $57 but it can now be found on Amazon for $35 - 3 year lifespan - runs on 3 AAA batteries 2) Kidde KN-COPP-B-LPM - continuous monitoring - stands upright or can be wall mounted - range 30-1000 ppm - can display peak level since last reset - tests every 15 seconds - alerts within 60 to 240 minutes for 70ppm, 10 to 50 minutes for 150ppm, 4 to 15 minutes for 400ppm - $22 - 7 year lifespan, chirps after 7.5 years to remind you to replace it - runs on 3 AA batteries for approximately 2 years 3) X-Sense CO03B - continuous monitoring - wall or ceiling mount - range 30-300ppm, good enough since you should leave the area immediately for levels over 200ppm - no peak level feature - response time is 0-3 minutes for 300ppm - $26 - 10 year lifespan, chirps after 10 years to remind you to replace it - runs on one 9v battery for 3 to 5 years For testing, I filled a garbage bag with car exhaust and placed all monitors in the bag. - The handheld alerted in 5 seconds and read over-range. It - The Kidde alerted after 20 seconds and read 823 ppm - The X-Sense did not alert during the first 30 second test and read 0ppm. I placed it back in the bag for 30 more seconds and it alerted and read it's maximum 300ppm. All 3 worked well. The handheld is best for verifying detections on the other monitors and testing while walking through the house since it is instant read and not designed for continuous monitoring. I placed the Kidde downstairs since I wanted one to place on a shelf for easy access. Since the X-Sense has the longest lifespan and longest battery life, I ceiling mounted it upstairs. ... show more
