Orpheus Theater Chooses Bosch Praesensa Evacuation System

One of the five largest theatres in the Netherlands, Theater & Concert Orpheus, has selected Bosch’s Praesensa for its new evacuation system.

The theatre has three halls with a seating capacity between 242 and 1,286 and a restaurant.

The requirement was to upgrade the current solution to meet the necessary regulatory requirements for public buildings and ensure it received the required EN certification. As an advanced and extremely cost-efficient fully IP-based system, featuring a smart-power concept and integrated redundancy, Praesensa is perfect for both centralized and decentralized network topologies.

The main challenge was the integration of the house PA and background music system with the voice evacuation system. The aim was for a solution that would give the theater complete control over all of its Dante-based audio facilities from one interface. Achieving this aim relied on Praesensa’s built-in OMNEO networking architecture. OMNEO is an IP-based architectural approach to connecting devices to exchange information such as audio content and device control. OMNEO is able to seamlessly integrate with Dante networks ensuring the voice evacuation system and the communications operate together.

The evacuation system needed to be able to completely take over from the house PA and background music system in the event of an emergency, but also give sufficient flexibility on the background music channels when the system is in normal operation.

A 32-channel Dante matrix sits at the heart of the solution, allowing the user to manage the entire house system without effecting the Praesensa public address and voice evacuation system.

The result is a combined solution that delivers what the client required. “Due to the very good cooperation between all involved parties, the migration went very well, without hiccups,” says Henry Bax from Connect AV, the systems integrator responsible for the project. “The goal of upgrading the evacuation alarm system to the latest regulations have been achieved.”
