Conference comms

by Mark Rowe

In Krakow, the International Conference and Entertainment Centre (ICE) is the city’s conference, exhibition and concert centre. Such large venues present a challenge to designers of evacuation systems. On the one hand, sound coming from the evacuation speakers must be loud and intelligible to inform every guest as to what he/she should do. On the other hand, the speakers should blend into the background rather than influencing the feel of the performance or audience space.

In Krakow’s ICE hemispheric loudspeakers from Bosch are part of a Bosch Praesideo Public Address and Voice Evacuation system. As a technician puts it: “If we had deployed standard loudspeakers for the evacuation system, we would have needed quite a few to establish an even sound coverage for the entire building. By using the hemispheric ones placed underneath the roof, five loudspeakers were enough to do the job, blending in discreetly with the room aesthetics.” The evacuation system was just one part of a comprehensive security and communications package at ICE built by Bosch. Almost the complete range of Bosch’s security and communication system portfolio is installed: not just evacuation, but also fire detection, video surveillance, public address, intrusion alarms, access control as well as conferencing systems.

The video surveillance in the facility is based on Bosch Video Management System as well as different types of cameras. Some cameras are the FLEXIDOME IP panoramic 7000 cameras offering 12-megapixel sensor resolution, with a fish-eye lens. These cameras provide a 180-degree or 360-degree overview without blind spots and enable capture of moving objects.

Decentralized Modular Fire Panel Series 5000 equipped with point-type and linear smoke and heat detectors are responsible for fire detection. Flat Fire Detectors Series 500 offering flush ceiling mounting were installed in representative rooms. Bosch provided the site with 2,000 fire detectors.

In July the site hosted the United Nations’ annual Convention for the Protection of World Cultural and Natural Heritage. Attending the UNESCO meeting were 1,966 delegates, another 1,000 service-providers and journalists and some 700 police and security staff. Nearly 50 ‘side events’ accompanied the 35 main meetings at the ICE. At the heart of the multi-lingual communication, managing simultaneous interpretations, was an conferencing solution from Bosch, with the Integrus language distribution system and the DCN conferencing solution (receivers for up to 1,500 participants).
