Nighthawk AC Plug-in Carbon Monoxide and Explosive Gas Alarm with Battery Backup

The Kidde KN-COEG-3 AC powered, plug-in CO and explosive gas alarm protects you and your family from two deadly threats. The KN-COEG-3 includes 9V battery back up that provides protection during a power outage, when AC-only units can not provide protection. By pressing the Peak Level Button you can see the peak CO 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.

• 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
