We supply install BOSCH Praesideo gets your message across, no matter what
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 de-centralized network architecture of Bosch Praesideo facilitates simple ‘daisy chain’ inter-connections. Units can be added or removed as required for total freedom of configuration.
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.
EVAC certified solution
Bosch Security Systems 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.
