Product Description

Product 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.

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. (Click each to enlarge)

Batteries don't fit!
4 Stars
Batteries don't fit!
I bought one of these units to replace the one that was on the wall when I bought my house four years ago. It seems like it worked really well so I purchased another one just like it when it expired. The batteries they send with the unit are supposedly special AA batteries for the unit. However, they were virtually impossible to fit into it. I eventually got two of the batteries to go in but the third one was not going to fit at all. So I just used a regular AA battery in that position. This was not fun for a person with severe rheumatoid arthritis. If you compare the battery they sent (left) to a usual AA battery (right), you can see that the positive end extends too far up on their battery.
Thank you for your feedback

Tal cuál se describe en la foto. El botón de prueba me parece muy útil para checar su funcionamiento semal, el sonido es bastante fuerte... aunque creo que como dice en las instrucciones es necesario uno para cada piso de la casa. El precio se me hizo muy accesible y acorde a la calidad del producto.
Hasta ahora no he probado la sensibilidad del aparato, pero he encontrado como hacer la prueba en internet... lo revisaré pronto
