The AirKnight AK1000 was designed with a built-in CO2 alarm option. If enabled, this CO2 alarm
beeps when CO2 levels surpass 1000 ppm (which is above the desired range). The purpose of the
CO2 alarm is to notify you right away so the appropriate action can be taken immediately to improve
CO2 levels (i.e. by opening a window / door or stopping the activity causing the high reading).
CO2 ALARM
Note 1: The default setting for the CO2 alarm is OFF. The AK1000 CO2 alarm can be turned on by
simply pressing the LEFT button on the top of the monitor twice. Exposure to less than optimal
CO2 levels for an extended period of time may not be healthy and it is therefore recommended to
turn this CO2 alarm function ON.
Note 2: If you have elected to turn the CO2 alarm on, please be aware that the CO2 alarm’s beeping
will stop automatically even when CO2 levels are still above 1000 ppm if the CO2 levels are
decreasing.
