Public address and voice alarm solutions by Bosch

State-of-the-art, public address and voice evacuation systems play a crucial role in addressing security and safety concerns. As a global leader and supplier of such systems, we ensure optimum effectiveness for our customers, as our paging and voice evacuation solutions excel in outstanding performance and reliability. Our voice evac systems cover the entire signal chain, spanning from the microphone and call station to the mixer/amplifier, controller, and loudspeakers. PA and voice alarm systems (PAVA) can be implemented to transmit flawlessly clear paging in every part of the building, while also delivering high-quality audio playback. Bosch provides systems and components around the world.

Easy migration towards IP

An IP-networked voice evacuation system can immediately accommodate changes to building use. When you add or define new areas for use, the system updates the changes effortlessly. When the system is IP connected, it can facilitate both centralized and decentralized topologies, as well as easy interconnectivity with other systems. Devices in an IP-based system can be managed via OMNEO media networking technology, enabling better audio quality and greater scalability than any other PAVA system.
