PRAESIDEO Digital Paging & Mass Notification and Voice Alarm System

Bosch PRAESIDEO is the world’s first fully digital, networked, public address and emergency sound system. The system’s unique optical network offers total freedom 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. PRAESIDEO redefines the boundaries of quality, flexibility and reliability.

The decentralized network architecture of Bosch PRAESIDEO facilitates simple ‘daisychain’ interconnections. Units can be added or removed as required for total freedom of configuration.

To support longer distances or multi-site applications, PRAESIDEO provides supervised communication using CobraNetTM or OMNEO/ DanteTM in a Local Area Network (LAN). The system can even be used in a multi-subnet Wide Area Network (WAN), using Voice over IP technology on networks with limited bandwidth, or using OMNEO Audio over IP for multi- channel, high quality, low latency, perfectly synchronized interconnections.

The network can be configured as a ‘redundant loop’ for extra reliability. This ensures that even a physical break in the fiber-optic cable won’t affect operation – critical for uninterrupted operation in emergency sound systems. To increase the system reliability even more, also other system elements can have a backup or spare device, up to the level of the network controller.

The OMNEO interfaces support Rapid Spanning Tree Protocol (RSTP) for automatic recovery of IP-audio connections when a network link would fail.

Bosch Building Technologies offers a total commitment to certification.

PRAESIDEO is EN 54-16 and ISO 7240-16 certified. Furthermore, it is compliant to many local evacuation standards.

To guarantee EVAC compliancy, installation must also be carried out according to exacting standards. Bosch runs a certified partner program with trained installers to add extra assurance that these requirements are met.

The system is straightforward to configure and re-configure, either locally or remotely, facilitating a quick response to changes. With the PRAESIDEO Logging software, logging information of multiple systems can be accessed for remote monitoring and diagnostics.

The Bosch PRAESIDEO products are easy to operate. Operators require very little explanation to competently use PRAESIDEO. Even the biggest systems are easy to operate via a PC or touch screen using the system’s open interface.

Bosch PRAESIDEO offers low cost of ownership. New or upgraded installations are highly cost effective thanks to its dual Paging & Mass Notification and voice alarm functionality, expandability, modular architecture and programmable flexibility. PRAESIDEO’s high reliability guarantees lower maintenance costs.

PRAESIDEO is the perfect solution for complex applications. It’s a fully digital system capable of handling even the biggest international airport. The Paging & Mass Notification and emergency sound system for an airport must deliver exceptional performance and reliability. Spoken messages must be intelligible even in zones with high background noise, like baggage handling areas.

PRAESIDEO is the perfect Paging & Mass Notification system to create a pleasant atmosphere for cruise ship passengers and ensure their safety in the event of an evacuation. Flexibility is guaranteed with a virtually unlimited number of zones and high number of audio channels, each with local source and volume control.

PRAESIDEO is the perfect solution for large venues with many zones such as stadiums. It handles message routing, public announcements, emergency voice evacuation, commentary for events and background music. PRAESIDEO also features advanced signal processing for perfect speech intelligibility.

PRAESIDEO is easily configured to meet the voice alarm, background music (BGM) and message requirements of large shopping centers. Its cost-effective system architecture uses a “daisy-chain” network topology, which allows system units to be located at any point on the network. Future expansion without major restructuring is possible.

PRAESIDEO is the perfect solution for larger applications with several locations, such as universities. It handles message routing (paging), emergency voice evacuation, local amplification for lecture theaters, commentary for sports events and background music in the catering zone.

PRAESIDEO is the ideal solution for effective sound management in large mosques. The world over, mosques stand proudly in cities and towns. They vary from small single-storey buildings to complexes with classrooms, offices, minarets, gateways and domes. Paging & Mass Notification in a mosque is primarily for amplifying prayers.

PRAESIDEO, with its extensive possibilities for integration, multi-zone functionality, standards compliance, and superb sound and speech reproduction, meets all the requirements for medium- and large-scale buildings for their voice evacuation systems. To improve safety and reduce response times, the system is often linked to the building’s fire detection system. That way, public alarms and voice evacuation programs can be initiated automatically, as soon as a fire is detected.
