The Shenzhen World Exhibition & Convention Center in China, the largest trade fair and congress center in the world with 19 exhibit halls and total exhibition space of more than 500,000 square meters, is now served by a custom security and communication solution developed by Bosch.
Loudspeakers covering a 20,000 square meter space with ceilings up to 16 meters in height needed to be powerful enough for instructions to be heard clearly and intelligibly by visitors in the event of an evacuation. The need was met with Bosch Hemi-directional ceiling loudspeakers, with 425 units installed in the exhibition halls.
The loudspeakers form part of the networked public address and voice evacuation system PAVIRO. Dueto its system architecture and use of IP technology, the system is used for selective music and audio playback in different areas. “The system has to facilitate both building-specific audio signals and system-wide announcements so that visitors feel safe and comfortable in the huge building. For example, an announcement in hall 1 shouldn’t interfere with the music in hall 2 – except in the case of an emergency,” explains Kevin XU, product marketing manager at Bosch Building Technologies, China.
The complete security and communications package consists of 27 PAVIRO systems and over 9,000 other loudspeakers, including ceiling-mounted and column models. In addition, Bosch also equipped the facility with an intrusion detection system and 1,000 detectors as protection against potential intruders.
