Carbon Monoxide Alarm – AC Plug-In with Battery Backup & Digital Display KN-COP-DP-B (Part No. 900-0278)

The KN-COP-DP-B Plug-In Carbon Monoxide Alarm is an easy-to-install, AC-powered safety device designed to protect your home from the dangers of carbon monoxide (CO) exposure. It plugs directly into a standard electrical outlet and includes 2 AA battery backup, ensuring continuous monitoring even during power outages when AC power is unavailable.

This model features a digital display that shows real-time carbon monoxide levels detected in the environment. The display automatically adjusts brightness in low-light conditions for better nighttime usability and comfort.

For enhanced safety awareness, the alarm includes a Peak Level button, which allows users to view the highest CO concentration recorded since the last reset. This helps identify past exposure events that may otherwise go unnoticed.

The KN-COP-DP-B is designed for long-term reliability with a 10-year product life and includes an end-of-life alert system that notifies users when the unit should be replaced. These alerts are intelligently designed to reduce disturbance, with low battery and end-of-life notifications suppressed in dark conditions to prevent unnecessary nighttime alarms.

The combination of plug-in convenience, battery backup protection, and digital monitoring makes this unit a dependable solution for residential carbon monoxide safety.
