Kidde Nighthawk Carbon Monoxide & Explosive Gas Alarm

Yes, the Kidde Nighthawk is a dual-sensor device designed to detect carbon monoxide as well as explosive gases, specifically natural gas (methane) and propane.

Yes. While the unit plugs into a standard 120V AC outlet for primary power, it includes a 9V battery backup to ensure the alarm remains operational during power outages.

The digital display provides a real-time reading of carbon monoxide levels in parts per million (PPM). It also features a peak level button that allows you to recall the highest concentration of CO recorded by the device.

This alarm is designed for standard wall outlets. Because it detects both CO and explosive gases, place it in an area where you have gas appliances, but ensure it is not obstructed by furniture or curtains that could prevent air from reaching the sensors.

The alarm emits an 85-decibel signal at a distance of 10 feet, which is the standard volume required to alert occupants effectively in a residential setting.

You should test the unit regularly using the integrated Test/Reset button to ensure the alarm and sensors are functioning correctly. Additionally, be sure to replace the 9V backup battery at least once a year or whenever the low-battery warning sounds.
