The KN-COPP-B-LPM Battery Operated Carbon Monoxide Alarm with Digital Display is an advanced safety device designed to provide reliable protection against the dangers of carbon monoxide (CO) in residential environments. Easy to install and suitable for all living areas, this alarm delivers continuous monitoring of CO levels—even during power outages when many CO incidents are most likely to occur.
A standout feature of the KN-COPP-B-LPM is its digital display, which shows real-time carbon monoxide levels ranging from 30 to 999 PPM (parts per million). The display updates every 15 seconds, allowing users to clearly monitor air safety conditions at a glance.
This model also includes an advanced peak level memory function, which records and displays the highest CO concentration detected since the last reset, with sensitivity as low as 11 PPM. This helps users identify previous exposure events for better safety awareness.
Powered by batteries, the KN-COPP-B-LPM ensures uninterrupted protection even during electrical failures. It also features a slide-out battery door for quick and easy replacement, along with a built-in safety mechanism that prevents the cover from closing unless batteries are correctly installed.
Designed for long-term reliability, this unit offers a 10-year operational life and is backed by a 10-year limited warranty, making it a dependable choice for modern home safety.
