IP-based emergency solution for stadium

The Praesensa public address and voice alarm system from Bosch is at the heart of the new safety system at Wycombe Wanderers’ Adams Park stadium. The football club chose infrastructure design specialist and system integrator Landways to design, fund and install this new system, alongside high-performance solutions for Wi-Fi and security, to help realise owner Rob Couhig’s ambitious vision for a great match-day experience.

The stadium officials eventually decided on the fully IP-based Praesensa system from Bosch, which covers all public areas of the 10 000-capacity stadium and features a smart-power concept with integrated redundancies to save on energy, hardware and space. Supporting the required intelligibility for voice evacuation, the system assures security for fans, complying with the requirements set by both the English Football League and the local council for ground safety and survivability in the event of an emergency. The solution can be utilised for pre-recorded messages from the system controller’s digital message storage, or for live announcements from two Praesensa emergency call stations.

The audio signals from Praesensa are fed into nine Dynacord MXE5 digital audio matrices via the built-in OMNEO IP architecture. This matches the benefits of a combined prosound and public address system with the mandatory requirements for voice alarm systems to be fully compliant to the required standards. Functioning as a communications hub, the MXE5 can be used for all peripherals, with comprehensive supervision and monitoring of all system-wide commands.

The seamless integration of all IP-based systems ensures that during an emergency, Praesensa messages are always ready to broadcast at the highest priority, with the entertainment audio automatically muted.
