“If using standard loudspeakers for the voice evacuation system, we would need quite a few products to provide sound coverage throughout the building. Instead, by using Bosch's Prasideo series hemispherical loudspeakers installed under the roof, only 5 devices are sufficient for the same purpose while still ensuring the aesthetics of the interior space”

With over 15,000 systems installed worldwide, Bosch's Praesideo is the number one solution for public address and voice evacuation applications. Premium sound quality, versatile operation, unlimited zones during installation, and continuous improvement programs help Praesideo consistently lead the market.

Outstanding features of the Praesideo Public Address and Voice Evacuation System

Versatile

Bosch Praesideo is the world's first fully digital, networked Public Address and Voice Evacuation System. The system's unique fiber optic network interface provides complete freedom in system design, noise-free audio, and high capacity that traditional systems cannot achieve. It is fully programmable and communicates with other security systems. This technology has redefined the boundaries of quality, flexibility, and reliability.

Scalable solution

The distributed architecture of the Praesideo audio system product line facilitates simple "daisy-chain" configuration. Devices can be added or removed as needed, providing complete freedom in configuration.

Uninterrupted operation

The network can be configured in a "redundant loop" style to increase reliability. This ensures that the system's operation is not affected even if a fiber optic cable is broken. This is a very important factor ensuring the uninterrupted operation of emergency voice alarm systems. To further increase system reliability, other system components can also have backup or redundant devices, up to the level of the network controller.

EVAC certified solution

Bosch Security Systems is committed to full compliance with certification standards. Praesideo is certified to comply with EN 54-16 and ISO 7240-16. In addition, the system also complies with many local evacuation standards.

To ensure EVAC compliance, installation must also be carried out according to precise standards. Bosch runs a certified partner program with trained installers to further meet these standards.

Outstanding benefits when the Praesideo Public Address and Voice Evacuation System becomes your choice

Simplified configuration

The system is easy to configure and reconfigure, internally or remotely, allowing for quick response to changes. With Praesideo Log software, login information for multiple systems can be accessed for remote monitoring and diagnostics.
