Bosch has announced the launch of PRAESENSA, the latest Public Address and Voice Alarm System that is IP-connected and fully-featured, setting a new industry benchmark within the region. All components of the system are networked, thereby ensuring the highest flexibility and scalability from small centralized to large decentralized systems.

The innovative multi-channel amplifier architecture with intelligent power allocation across the amplifier outputs and integrated spare channel significantly improves the effective utilization of available power, regardless of the loudspeaker load in each zone. As a result, fewer amplifiers are needed, saving up to 50 percent on space, energy and backup battery power and leading to a very competitive cost of ownership.

PRAESENSA offers the highest level of data security and full network link redundancy with smart integration of functions and backup facilities. No single point of failure is core to the system concept and only a few different devices are needed to fulfill all system and user needs.

The intuitive interface of the call station provides an optimized user experience through an effective combination of touch screen and selection buttons. Clear progress guidance and status feedback ensure comfort and ease of use for operators.

PRAESENSA is a comprehensive system that is compliant to the evacuation standard EN 54-16 and adapts easily to changing needs. It offers full sound control per zone to create the right atmosphere with background music and to meet speech intelligibility requirements for business and emergency operations, making it a fit-for-purpose solution for consultants, installers and building owners alike.

Being a trusted partner with more than 90 years of experience in Public Address Systems, Bosch introduced the first networked digital Public Address and Voice Alarm System 15 years ago and continues to develop innovative technology and solutions.
