CO2 Alarm Station (Amber light)（AS-3）
 
The AS-3 CO2 Alarm Station is an audible-visual alarm module that features a Amber LED display indicator and a LCD
digital ppm level display. It is designed to be mounted outside of grow-room or grow facilities to monitor the CO2 ppm level.
The AS-3 can be linked to either AL-1or AL-2 CO2 sensors channel, or it can be linked to both sensor channels for complete redundancy.
 
The AS-3 will sound an audible alarm and blink the Amber LED indicator in the event of the CO2 level going above the user’ s preferred level set in the Carbon-X main controller.
 
*Note: The AS-3 requires the SPH-1 for supplemental power.
