Kidde COBDL10 Carbon Monoxide Detector — 10-Year Battery, Low-Level Detection, Backlit Display

Protective CO detection for home and family

The Kidde COBDL10 Carbon Monoxide Detector brings you advanced, continuous awareness of carbon monoxide levels in your living spaces. With a premium low-level alert, it can signal risks sooner, helping you act quickly and safely. This detector combines a loud 85 dB alarm, a clear backlit digital display, and LED status indicators to communicate current conditions at a glance.

Designed for everyday homes, it delivers a maintenance-free experience thanks to a built-in 10-year battery. You won’t hear low-battery chirps, and you’ll be reminded when the 10-year period ends so you can plan for a replacement. The Peak Level memory displays the highest CO concentration recorded since the last reset, giving you a concise history of exposure without guesswork. The test/hush button provides a quick check or temporary silence when conditions are safe to do so.
