BETA CO detectors warn the gas presence in the environment where they are installed with an optical and acoustic signal.
CO version are calibrated to detect the following concentration: 50 ppm x 70 minutes / 100 ppm x 20 minutes / 300 ppm x 1 minute. This threshold are guaranteed for a maximum period of 5 years.
After that period, an optical signal warns to replace the unit.
