The AS-4 CO2 alarm control panel is an acoustic-visual alarm module with a blue LED light indicator. It has a digital LCD display to show the ppm value. It is designed to be mounted outside of grow rooms or grow fixtures to monitor CO2 emissions. The AS-4 can be connected to one of the CO2 sensor channels AL-1 or AL-2, or to both channels for complete redundancy.
