CO-USB Carbon Monoxide Alarms
The CO-USB is the original version.
The CO-USB-Battery is the highest-end version and adds 8-hour battery life, a very loud 85 dB built-in annunciator, and a lanyard connection
The CO-USB-UP flips the orientation of the LEDs to better accommodate panel installation, while retaining the features of the CO-USB Original. However, it does not have the digital output port.
