The Kidde KN-COEG-3 is a dual-threat AC plug-in alarm protecting against both carbon monoxide and explosive gas (natural gas and propane). The digital display shows current CO concentration levels. Peak level memory recalls the highest CO concentration detected. A Test/Reset button silences alarms and verifies circuit operation. This alarm is ideal for homes with gas appliances, furnaces, or propane systems where both CO and explosive gas hazards may be present.
What types of explosive gas does the KN-COEG-3 detect?
The KN-COEG-3 detects natural gas (methane) and propane — the two most common explosive/flammable gases in residential settings. This makes it especially valuable in homes with gas furnaces, stoves, water heaters, dryers, or propane systems.
Can this alarm detect both CO and gas simultaneously?
Yes. The alarm monitors for carbon monoxide and explosive gas simultaneously. Each threat triggers the alarm independently with the appropriate alert signal. The digital display specifically shows CO concentration levels.
