Praesensa: high-performance IP public address and voice evacuation system

All Bosch Praesensa components are networked, ensuring maximum flexibility and scalability, from small to large centralized systems.

Developed by Bosch, Praesensa's new voice evacuation and public address IP system incorporates this manufacturer's Omneo IP architecture, that supports Dante audio networks, AES67 and AES70 protocol, as the company has recently shown during its participation in Sicur 2018.

With features that ensure data security, as well as a redundant network connection, this system is based on the concept of absence of a single point of failure, and only a limited number of different devices are required to respond to the needs of the system and the user.

Praesensa's multichannel amplifier architecture, with intelligent power allocation through the amplifier outputs and with integrated backup amplification, significantly improves the effective use of available power, regardless of the distribution of speaker load in the areas.

The result of this technology is that installations need fewer amplifiers, saving up to the 50% space, power and battery backup, according to the data provided by the company, which translates into a competitive cost of ownership of the system.

Available on the market from July 2018, Praesensa has an interface that combines a touch screen with radio buttons that improves the user experience, with clear information on the progress of ongoing actions and the state of the system.

Praesensa is a comprehensive system that complies with the EN evacuation standard 54-16 and easily adapts to changing needs. Offers full sound control by zone to create the right environment with background music, as well as to meet the intelligibility requirements required in commercial and emergency operations.
