Digital PA and emergency sound system

November 2008 Infrastructure

Bosch Praesideo is a fully digital public address and emergency sound system. The system’s optical network offers total in-system design, interference-free audio and a high level of redundancy that traditional systems cannot offer. It is fully programmable and interfaces with other security systems.

With 28 dynamically assigned digital audio channels, digital message management and background music (BGM) routing to a virtually unlimited number of zones, Praesideo is ideal for medium- to large-scale public address and voice alarm applications. The system is IEC60849 certified and complies with all major standards for emergency evacuation.

Bosch Praesideo is fully supervised, and constantly monitors system control, amplifier operation, microphones, loudspeaker line integrity and individual loudspeakers. Built-in redundancy and automatic spare amplifier switching guarantees continuity.

Praesideo offers low cost of ownership. New or upgraded installations are highly cost-effective thanks to its dual public address and voice alarm functionality, expandability, modular architecture and programmable flexibility. Praesideo’s high reliability guarantees lower maintenance costs.
