Warning level 3 is not output in the default device parameter set.
Example for parameter set 1 'Balanced EU2' @ 55 ±5 ppm CO:
At 50 ppm CO, alarming must take place after between 60 and 90 minutes.
perating temperature of ≥80
°C, the CO sensor may not function reliably.
Irreversible signaling of a critical fault therefore follows after four hours.
The point detector may only be used in continuous operation within the specified
temperatures!
