The room contains an extractor fan and a fresh-air fan.
Both fans are monitored by a flow sensor.
The pressure in the room must not be allowed to rise
above atmospheric pressure.
The fresh-air fan must only be switched on provided reli-
able functioning of the extractor fan is signaled by the
flow sensor.
A warning lamp indicates if one of the fans fails.
