The entire system is powered from a single 110V socket which provides high visibility for gas detection and temperature on a white-on-black LCD display. Audible and visual alarms are provided for three concentrations of CO2 for the default settings at 5,000, 15,000 and 30,000 parts per million (ppm). It is not recommended to change these levels, but for special circumstances it can be done.
