Kidde Carbon Monoxide Detector – Plug-In CO Alarm with AA Backup (3rd Edition)

Protect your home with Kidde CO Detector

The Kidde Carbon Monoxide Detector is a plug-in device that uses an electrochemical sensor to monitor carbon monoxide levels in your living spaces. When CO is detected, an 85 dB alarm may sound to alert you and your family, while a bright LED indicator shows the device is actively protecting your home. The unit plugs into a standard 120V outlet, and two AA alkaline batteries are included to provide backup power during outages. This combination of continuous monitoring and reliable backup can enhance your safety routine without requiring complex setup.

A digital CO display updates every 15 seconds, offering a real-time view of the current readings. The Peak Level Memory records the last detected CO event or the most recent test, helping you review past activity at a glance. If a false alarm occurs due to steam from cooking or showers, the Smart-Hush button silences the alarm for about eight minutes, allowing you to resume your day while maintaining ongoing CO detection.

UL Certified and backed by a 10-year limited warranty, this detector is designed for residential use and aligns with common safety standards. For best protection, consider placing a detector on every level of your home and near bedrooms to ensure audible alert coverage even when you are sleeping.
