3 System introduction
With PRAESENSA, Bosch has set a new standard in Public Address and Voice Alarm systems.
With all system elements being IP‑connected and using state‑of‑the‑art technologies, this
system combines cost efficiency and audio quality with ease of installation, integration and
use. IP‑connectivity and amplifier power partitioning enable new levels of scalability and
adaptability, and combined with local backup power facilities this makes PRAESENSA equally
suited to both centralized and decentralized topologies. PRAESENSA uses only a few different
but very flexible system devices, each with unique capabilities, to create sound systems of all
sizes for an extremely wide range of applications. PRAESENSA fits to an office with
background music in the reception area and some occasional calls, as well as to an
international airport with many simultaneous (automated) announcements for flight
information, and carefully selected music programs in lounges, restaurants and bars. In all
cases, it can be installed to operate also as a certified voice alarm system for mass notification
and evacuation. System functions are defined and configured in software and system
capabilities can be enhanced via software upgrades. PRAESENSA: one system, endless
options.
