Kidde Carbon Monoxide Alarms & Detectors
Kidde Carbon Monoxide Alarms and Detectors
Kidde is one of the most widely recognized names in residential fire and life safety, and their carbon monoxide alarm lineup reflects decades of product development focused on reliable home CO detection. Kidde CO alarms use electrochemical sensing technology — the most accurate and stable sensor type for residential CO detection — to continuously monitor air quality and alert occupants before CO concentrations reach dangerous levels.
Kidde's CO detector product line spans simple battery-powered units through smart Wi-Fi connected alarms, giving homeowners options that match their home infrastructure, budget, and desired level of connectivity. All Kidde CO alarms are UL 2034 listed, meeting the nationally recognized standard for residential carbon monoxide alarm performance and alarm threshold requirements.
Kidde CO Alarm Features
Most Kidde CO detectors include a digital display showing the current CO concentration in parts per million — an important feature because it allows homeowners to identify low-level CO accumulation that causes symptoms like headaches and fatigue even when CO concentrations remain below the alarm threshold. The peak CO memory function records the highest CO level detected since the last alarm reset, providing a record useful for identifying intermittent CO problems from appliances that only produce elevated CO under certain operating conditions.
Kidde combination alarms detect both smoke and carbon monoxide in a single unit, eliminating the need for separate devices in bedrooms and common areas. These combination units use different alarm tones and voice announcements to distinguish between CO and smoke detection events, so occupants know what type of hazard requires their response.
Smart and Interconnected Options
Kidde's smart CO alarms connect to home Wi-Fi and send alerts to the Kidde app on smartphones, providing notification even when the homeowner is not present to hear the audible alarm. For homes with interconnected smoke and CO alarm systems, Kidde offers hardwired CO alarms that trigger all connected alarms simultaneously when any single unit detects CO — a whole-home alert that gives occupants maximum warning time to evacuate.
