Kidde KN-COPP-3 Carbon Monoxide Alarm

Yes. While the unit is primarily powered by a 120VAC outlet, it includes a 9V battery backup to ensure it continues monitoring for carbon monoxide during power outages.

The digital display provides a real-time readout of carbon monoxide concentrations in parts per million (PPM). It updates every 15 seconds to keep you informed of current air quality levels.

This model features a peak level memory function. By pressing the peak level button, you can view the highest concentration of carbon monoxide recorded by the device since the last time it was reset.

You have flexibility in how you place the alarm. It can be plugged directly into a wall outlet, positioned on a tabletop, or mounted using the included 6-foot power cord for placement in a more convenient location.

No, this unit does not support interconnection. It operates as a standalone device and will not trigger other alarms in your home if it detects carbon monoxide.

The alarm emits an 85-decibel signal at a distance of 10 feet, which is the standard volume designed to be loud enough to wake or alert occupants in the event of a danger.
