Carbon monoxide (CO)
Warning: in detecting carbon monoxide (CO), the levels and
intervention times are processed and controlled by
a microprocessor. The “Sensitivity” control must
obviously be set in the “0” position.
– Carbon monoxide:
“thr time”
< 50 ppm: no alarm
50...100 ppm: 60 minutes
100...300 ppm: 10 minutes
> 300 ppm: immediate alarm
–Carbon monoxide (CO) pre-alarm:
time between
exceeding alarm threshold and alarm
