CO alarms manufactured in accordance with standard EN50291 will activate if it has detected a certain concentration for a given time, as described below:
- 50 ppm: Alarm between 60 and 90 minutes
- 100 ppm: Alarm between 10 and 40 minutes
- 300 ppm: Alarm within 3 minutes
This ensures that the alarm activates when dangerous levels of CO have built up and immediate action is required. Please refer to the manufacturers instructions for specific guidance on the carbon monoxide alarm.
