Starting from rest, when the toxic gas concentration overcomes the ventilation level 1 in the
zone, this ventilation activates after having been above this level for a time greater than the
activation delay time 1.
If the toxic gas concentration in the zone drops below ventilation level 1, it will stop after the
stop delay time.
The Table 3 shows the default values and range of values that can be configured through the
