The Paviro public address and voice evacuation system from Bosch features ehanced
functions and is ready for larger applications, thanks to state-of-the-art IP networking
The PAVIRO public address and voice evacuation system from Bosch offers users new
hardware and software features for enhanced usability and for use in larger
applications. Using IP technolgy, PAVIRO provides a highly flexible, reliable and secure
system solution with superior audio quality and low latency. As installers can use
existing networks in the building infrastructure, relying on IP technology also results
in faster installations and lower implementation costs. Furthermore, PAVIRO can be
interconnected with other devices such as PCs or laptops over IP protocol,
allowing for efficient remote control, danostics and maintenance via the Internet.

The PAVIRO public address and voice evacuation system IP functionality and
connectivity is achieved via the newly released Dante network interface module (OM-
1) from Bosch. Now it is possible to create a 16-channel Dante audio network
between the individual controllers. This not only improves the size; the IP networking
architecture allows users to create multi-controller network topologies for larger
areas via up to four de-centralised controllers. This also means less cabling – a big
cost-saving factor in some applications.

At the maximum configuration level, the PAVIRO system can now address up to 984
zones with a total of 164,000 watts of amplifying power in one system, making the
system suitable for bigger installations in which a large number of zones and
loudspeakers are needed. It also caters to existing installations whenever the
infrastructure of building changes and additional rooms have to be addressed. In
addition, the network configuration provides redundant channels for safety
purposes – in case of an emergency these channels will always work for evacuation
signals, even if a controller loses network communication.

PAVIRO is a unique, high-quality Public Address and EN 54-certified Voice Evacuation
System from Bosch. The certification allows architects, planners and specifiers to fulfil
mandatory requirements specified in many tenders. In addition to professional
audio quality, PAVIRO’s highly adaptable system architecture makes it ideal for small-
to mid-sized offices, regional airports, mid-sized hotels, factories, schools and
department stores. PAVIRO now also includes loudspeaker zone monitoring
and 30 minutes of flash memory for recordings of evacuation-related communication.
