In addition to the main hall, the ICCW is a 5-storey building, with a three-floor entrance atrium, meeting rooms, two car park levels and kitchens, as well as a 1500 raked seating auditorium, which proved a major challenge. “After considering Stage Electrics’ requirements we came up with the most fitting topology for every space, considering all parameters,” he said.
The large atrium presented a particular challenge with regard to STI, and this was overcome, with the design validated by EASE measurements, based upon predicted performances.
This approach fulfilled the pre-conditions for a consistent design. In the main hall, DP 1420EN aluminium sound projectors, deployed at a height of nine meters from floor level on a rain-diffusion basis, allow for a measured average STIPA figure that exceeds performance requirements of the Voice Alarm standard.
Regarding EN54-16 certified electronics, signal distribution is via three technical rooms, sharing monitored data and audio (Dante) upon an Ethernet fibre ring-configured network. Besides the emergency facilities, the VA system needed to allow for local inputs broadcast on a zonal basis supporting a third party audio-over-IP distribution system that manages routing and room combining capability by means of wireless control surfaces.
Finally, the client turned to RCF’s wiring department for PAVA rack building, device wiring, testing and pre-configuration. Acceptance testing activity with Stage Electrics was also managed at RCF’s Reggio Emilia HQ. The final count consisted of six cabinets housing EN54-16 certified electronics (matrices and amplifiers), EN54-4 certified battery chargers for secondary power feed (including batteries), distributed in the three technical rooms and interconnected on an Ethernet fibre ring-configured network supported by dedicated network switches programmed by RCF.
The PAVA installation (and wider technical requirements) were commissioned by RCF personnel alongside Stage Electrics team members, comprising Simon Cooper, technical project manager Chris Brant, site team leader Aaron Godsmark and commissioning engineer Steve Chappell.
Speaking of the success of the integration ICCW Head of Technical Services, Simon Denman-Ellis, said: “What the team liked most is the ease of use with the RCF systems. Everything just works seamlessly, a real plug and play set-up but with the high-end sound and reliability you would expect to find in a much more complex system.”
