The smoke extraction system, also known as overriding programmable logic control (OPLC) for Berlin’s much delayed future airport had its final test at the end of last week. The test was overseen by the responsible authority TÜV Rheinland (Technical Inspection Association) and was approved without any defects. The TÜV delivered the test reports regarding the highly complex Siemens equipment to the airport on April 15.
Prof Dr-Ing. Engelbert Lütke Daldrup, CEO of Flughafen Berlin Brandenburg GmbH commented: “The TÜV-approved smoke control system marks a milestone in the completion of BER Terminal 1. Siemens has completed this complicated system on schedule, and I would like to express my thanks for the good cooperation in this particular situation. I would also like to thank the FBB Project Management Team and FBB Team of Experts for the smoke extraction systems that completed the difficult technical installations in BER with tireless dedication.”
The overriding programmable logic control (OPLC) ensures functioning smoke extraction and controls the interaction between the circulation of fresh air and mechanical smoke extraction, such as between exterior openings and fans. In the event of a fire, more than 120 smoke extraction machines provide a 8ft (2.5m) smoke-free layer for around 15 minutes, in which time people near the fire can safely evacuate the building.
