Regular price $199.00 Sale

The AS-4 CO2 Alarm Station with a Blue light alarm module comes with a Blue light LED display indicator and an LCD digital ppm level reading. It is designed to be mounted outside of the space to be monitored and will display the CO2 ppm level. The AC-4 can be linked to either the low or the high-level CO2 sensors, or it can be linked to both sensors for complete redundancy. The AS-4 will sound an audible alarm and blink the Blue LED indicator in the event of the CO2 level going above the user’s preferred level set in the main controller.

Please Note: The AS-4 requires the SPH-1 for supplemental power.
