This system is based on IP technology, compatible with Dante audio protocol and complies with EN-54-16 evacuation regulations.

Available on the market, praesensa's public address and voice alarm system that just introduced Bosch offers a comprehensive and advanced security solution, IP-based with Dante audio, incorporating. a new flexible power-sharing technology per channel.

When using an Omneo IP architecture, compatible with Dante audio, the system offers not only greater flexibility and scalability to the architecture, but safety and reliability, since the audio and control network can be encrypted to prevent unwanted computer attacks.

Thanks to the innovative architecture of amplifiers, power is intelligently allocated so that the system adapts individually to the loads of the connected speakers, ensuring high availability thanks to multiple integrated redundancies.


Specifically,, Bosch Praesensa features 600W IP digital stages, with versions of 4 (PRA-AD604) and 8 Channels (PRA-AD608), with adaptive power per channel. It also features a backup amplification integrated by channel, that doesn't occupy channel and no wiring, to deliver more power with fewer amplifiers, energy efficiency and costs.

Praesensa PRA-MPS3 equipment serves both as a main power supply and reserve via a single 12V battery, Omneo network switch with POE and fiber optic ports.

For its part, the calling stations of this public address system: PRA-CSLW (for wall mounting) and PRA-CSLD (Desktop), incorporate a touch screen, very simple to use, and a physical button with indicators.

Bosch Praesensa meets EN evacuation standard 54-16 and it's a comprehensive sound solution that adapts to all kinds of spaces, by curbing full control of sound by zones to create the right environment with music, as well as help meet intelligibility requirements in general messages (live or pre-recorded to different areas) or emergency, as well as in special environments where audio delays and signal processing are needed, like in a tunnel.
