NOTICE
This is not a safety function for extracting smoke from buildings
The function can only be used as a supplement to use the air supply system in
support of extracting smoke in the rooms with VAV extract air as long as the
associated components are still operational.
All supply air and extract VAV in the rooms can be used to purge room air if
both digital commands are activated together for HVAC positive and negative
pressure. The command is executed at the highest priority and cannot be
locally overridden in the room or from another central operation.
HVAC devices can only be manually or automatically operated after this digital
command is reset.
All supply air VAV and extract VAV are controlled in the room to a configured air
flow if the digital commands are activated for this type of HVAC purge. The
value can be configured separately for all supply air and extract air VAV in the
room.
