Bosch digital announcement system given for modern international airport at Bahrain

Bahrain International Airport is an important regional hub for all aviation activities because of its geographical location in the Middle East. The busy airport which is served through 30 different international carriers has around 8 million passengers every year. In order to handle a passenger capacity of 12 million in the near future there are plans to upgrade the airport with an additional terminal.

Business objective:

To provide announcements throughout the airport with high
clarity on a zone wise selection basis, the system in consideration had to provide the following essential functions:
- Digital base platform with full scalability
- Integrated digital audio database providing natural sounding
announcements in Arabic, English and Hindi
- Allowance for the automatic broadcast of Islamic Prayer Calls
(Aadhan = call to prayer) at 5 different times a day, varying
with each day throughout the whole year
- Allowance to be integrated to a "Flight Information Display System"

Solution:

Given the critical nature of the project, it was essential for the customer "Civil Aviation Authority Bahrain" to award the Bahrain International Airport. The fact that the earlier solution, based on Philips SM40 equipment (Philips-CSI was acquired by Bosch Security Systems in 2003) had served well over the last 12 years made the choice for a follow-up system fairly simple. An integrated Bosch Praesideo solution offered by the installer Mohammed Fakhroo & Bros was finally selected by the customer.

For meeting the requirements as well as the objectives of the customer, the following equipment design was defined:

1. An equipment rack consisting of a Praesideo network controller and an assortment of 22 Praesideo amplifiers, providing the possibility to integrate additional units as well

2. More than 1150 constant directivity ceiling loudspeakers distributed in 20 zones

3. 13 Praesideo call stations to be used in gates for local or common area announcements

4. A PC Master call station with geographic lay-out for selecting the particular required zone operational ease for multiple staff handling different shift duties was given.

5. A special audio server, with a customised audiodata base as well as the relevant interface to the Praesideo platform
and "Flight Information Display Sytems" (FIDS) supported by a XML file exchange mechanism
