Kidde’s KN-COPP-B-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. This unit features a large digital display indicating the level of CO that the unit is sensing, and it updates the status every 15 seconds for timely and accurate readings. The free-standing design allows for attachment to a wall or placement on a counter or nightstand for convenient and comprehensive protection.
The KN-COPP-B-LPM also includes a slide-out battery door (requires 3 AA batteries, included) 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.
However, one major concern the reviewers mentioned is that this device does not monitor or detect low non-alarm CO levels that could be hazardous in the long run.
Overall, the Kidde KN-COPP-B-LPM Battery-Operated Carbon Monoxide Alarm with Digital Display is highly recommended for its reasonable price and safety features. This device has an expected shelf life of 7-year and comes with a 5-year manufacturer’s limited warranty.
