The AS-2 CO2 alarm station combines an audio visual alarm module with a color coded LED display indicator and a digital ppm LCD level readout. It is designed to be mounted outside the space to be monitored and will display the ppm CO2 level. The AS-2 can be connected to low or high level CO2 sensors, or it can be connected to both sensors for full redundancy.
The green LED indicator shows that the CO2 level is below 800ppm, which means that access to the room is safe. The yellow LED indicator shows a CO2 level equal to or greater than 800 ppm, which means that additional CO2 is in use. The AS-2 will emit an audible alarm and a flashing red LED indicator if the CO2 level exceeds normal or safe levels.
