· Die Konzentration sollte nicht viel höher als 1000 ppm liegen, sagt das Umweltbundesamt (PDF), Ein CO2-Sensor kann Alarm schlagen, wenn dieser Wert erreicht ist. CO2-Sensoren werden deshalb auch schon CO2-Ampeln genannt. Sie liefern eine Anzeichen dafür, dass sich Aerosole im Raum verteilen. Zwei Lehrerinnen im Bekanntenkreis erzählten mir, dass sie es nicht immer schaffen, …
The gas sensors in CO alarms have a limited and indeterminable life span, typically two to five years. The test button on a CO alarm only tests the battery and circuitry, not the sensor. CO alarms should be tested with an external source of calibrated test gas, as recommended by the latest version of NFPA 720. Alarms over five years old should be replaced but they should be checked on ...
