The Kidde plug-in carbon monoxide (CO) and explosive gas alarm protects you and your family from two deadly threats: Carbon Monoxide and Natural Gas leaks. It includes 9V battery back up that provides protection during a power outage, when plug-in only units cannot provide protection. By pressing the Peak Level Button you can see the peak carbon monoxide level recorded by the alarm since it was last reset or unplugged. The continuous digital display shows you the level of carbon monoxide (if any) the unit is sensing as well as if gas is present. The gas sensor is a metal oxide sensor designed to detect natural gas (methane) or propane.
FEATURES
- Digital Display – Displays the level of carbon monoxide the unit is sensing.
- Test/Reset Button – Tests unit’s electronic circuitry operation and allows you to immediately silence the alarm.
- Peak Level Memory – Recalls the highest carbon monoxide concentration detected.
OPERATION
- Sounder Alarm – Offers a loud 85-decibel pulsing alarm that will sound to alert you to a potential problem.
- Carbon Monoxide – Four quick beeps, followed by five seconds of silence, followed by four quick beeps. Repeat with a number showing in the display (CO concentration in parts per million).
- Gas – One second of alarm on, one second of alarm off, repeating with “GAS” shown in display.

At DTE, safety is our highest priority. That's why we're making combined carbon monoxide (CO) and natural gas detectors available through the DTE Marketplace—to help you add another layer of protection for their home or business.
Detectors can provide life-saving alerts, but they are only one part of an overall safety plan. We encourage customers to stay informed about carbon monoxide and natural gas safety and to follow all manufacturer instructions for installation, testing and maintenance.
Know the Difference
Natural Gas
- Natural gas is odorized with a "rotten egg" smell to help with detection.
- If you suspect a natural gas leak, leave the area immediately, go to a safe outside location where you no longer smell natural gas, and call 911 before calling DTE at 800.947.5000. It’s a free service for customers, 24/7.
- Do not attempt to locate the leak or create a spark by using appliances, electronics, phones, light switches, garage door openers, matches, lighters, or other open flames.
- Do not re-enter until first responders or DTE says it is safe to do so.
Carbon Monoxide (CO)
- Carbon monoxide gas cannot be seen or smelled.
- Carbon monoxide poisoning symptoms are similar to the flu: Breathlessness, dizziness, fatigue, headaches, and nausea.
- If your carbon monoxide detector alerts you or if you suspect a carbon monoxide problem, immediately leave the building and get into fresh air.
- Call 911 and, if needed, seek medical assistance.
- Do not re-enter the building until it is determined to be safe by first responders or DTE.
