The PRAESIDEO system offers integrated digital audio processing (DSP) functions to "peripheral devices" such as call stations and amplifiers. The accessible DSP power then scales automatically with the number of connected devices. Since system components are networked, they can be easily deployed

The PRAESIDEO network allows simple "daisy chain" configurations. It offers complete freedom with units that can be added and removed as needed 
To support longer distances or multi-site applications, the PRAESIDEO system allows supervised communication with CobraNet ™ or OMNEO / Dante ™ 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 in limited bandwidth networks or OMNEO Audio over IP for multi-channel, high quality, low latency, perfectly synchronized connections.

As part of Bosch Security Systems' commitment to comply with international standards, PRAESIDEO also meets legal requirements for voice alarm systems. Bosch PRAESIDEO is EN54-16 and ISO 7240-16 certified. This system also complies with many local evacuation standards. DNV GL type approval Bosch PRAESIDEO, has received a type approval certificate from DNV GL for installation on all vehicles classified by DNV GL.

PAVIRO Public Address and Emergency Announcement System

Paviro is a unique, high quality Public Address and EN54 certified Voice Alarm System that offers professional quality sound thanks to its 24-bit special digital processor, superior digital-to-analog converters and unique Signal / Noise Ratio (SNR). Due to its highly adaptable system architecture, it is ideal for small to medium offices, regional airports, mid-sized hotels, factories, schools and department stores

Using IP technology, PAVIRO provides a highly flexible, reliable and secure system solution with superior sound quality regardless of project size. Equipped with the optional Dante network interface module (OM-1), it is possible to create a 16-channel Dante voice network between single controllers. This increases the size of the system with up to four decentralized controllers, but means less wiring using standard Ethernet connections and components, resulting in greater cost savings across multiple applications.

At its maximum configuration level, the PAVIRO system can address up to 984 zones with a total of 164,000 watts in one system, making the system appropriate for large institutions. It also enables existing installations to be easily adapted when the infrastructure of the building changes and supplementary rooms need to be addressed. In addition to this, the network configuration provides redundant channels for security purposes. In an emergency, these channels always work for evacuation signals even if a controller loses network communication..

PAVIRO offers highly flexible combinations of announcement / music distribution thanks to its four-channel matrix architecture. For example, you can broadcast classical music to some of the six regions and pop music to another. You can also send one or more announcements in any region without interfering the music. Depending on your needs, you can also choose from one to four channels for each router, thus minimizing power consumption (by minimizing the number of amplifiers) or further increasing flexibility. Such versatility is not found in other systems in this class.r.

Each PAVIRO amplifier has two auxiliary audio inputs that allow you to connect additional audio sources. This for example guarantees that system channels are not used for external inputs that are sometimes required for AV presentations. In addition, PAVIRO's high flexibility and intelligent combination of input and output matrices help a hotel maximize its suitability for business events, ensuring that fewer number of amplifiers are required for your application and Voice Evacuation..

Operating costs are low as PAVIRO uses the latest high efficiency class D amplifiers and intelligent power management hardware and software. These features significantly reduce power consumption. Each router can handle up to 24 loudspeaker lines using a single type of amplifier. Thus, a lot of adaptability is created within the system. Power load sharing across the zones (2 W to 500 W) allows combinations of low and high power zones within the router, making the system even more flexible

PLENA Public Address and Voice Alarm System

The PLENA Public Address and Voice Alarm System range is an ideal evacuation, message and background music solution for various locations such as schools, hotels, shopping malls, factories, offices and similar applications where public safety is of paramount importance.

The system, which is fully compliant with EN54-16 and ISO7240-16 standards, has an expandable structure up to 120 zones. The voice alarm controller, which has a 240 W internal amplifier, can be expanded with 6-zone routers and is supported by 120W, 240W and 480W amplifiers.
