The CO2 TFT is a electro-chemical carbon dioxide detector. CO2 is slightly lighter than air. The recommended position to mount the CO2 sensor is 5ft 6″ inches above ground level. When the sensor head detects carbon dioxide at a level exceeding 4500ppm for the attached system will trigger into the alarm state. This is re-settable by rectifying any gas leak, improving air flow allowing the sensor head to clear and restarting the Merlin panel.
