Dubai International Airport equipped with Public Address and Emergency Sound System from Bosch

With more than 120 Active Line Arrays, 3500 ceiling speakers, 250 sound projectors and 400 XLA Line Arrays, the extension of Dubai International Airport with Terminal 3 and Concourse 2 is a huge Praesideo-controlled installation. All these speakers are driven by more than 300 amplifiers interconnected with 125 Cobranet units in a single system controlled by 44 Network Controllers in a redundant configuration that is fully EVAC compliant.

Moreover, it is just what this absolutely no-compromise, high-quality customer experience demanded for the main hub of the United Arab Emirates' main carrier: Emirates Airline. Terminal 3 is perhaps the most powerful example yet that Dubai International Airport is totally committed to comfort, style and professionalism.

The heart of the system
The central control of this system consists of a software application provided by the Building Information System (BIS) from Bosch. It is the heart of the system that takes care of central logging, redundancy handling, PC call-station functionality and the interfacing to the automatic announcement system, as well as other airport systems such as the fire alarm, flight information and building management systems.

Innovative thinking
Given the size of this project, new ways of designing, logistic processing and shipments needed to be developed on the fly. For the special architecture of this airport, the German company Rahe-Kraft was subcontracted to provide an optimal acoustic design to meet the customer's specifications. This was proven during a successful trial period that ended in October 2010. With Dubai International Airport, Bosch has completed an immense project and gained a great deal of useful experience to be shared with its partners.
