Introducing PRAESENSA, the new standard in Public Address and Voice Alarm (PAVA) systems from Bosch. The system provides high-quality audio for music or messaging to every area in your building and is controlled via the intuitive graphical user interface on the call station touchscreen, or via personalized software running on a tablet or PC. Easy to install and highly cost-efficient, this advanced Public Address and Voice Alarm system brings peace of mind to a new level.
Fully IP-based and fully-featured, this is a state-of-the-art Public Address and Voice Alarm system. Installation and integration are straightforward, and it delivers great audio quality with an easy-to-use interface. PRAESENSA uses IP-connectivity and a smart power concept with integrated redundancies to give you an extremely cost-efficient system, equally suited to either centralized or decentralized topologies
- All PRAESENSA system devices use dual Ethernet ports, supporting RSTP, for automatic recovery from a broken network link.
- Power supplies have battery backup facilities, making them immune to mains failures.
- In the case of a failing amplifier channel, there is an integrated, additional spare amplifier channel in the 8- and 4-channel amplifiers, which will automatically take over.
- Each amplifier has double power converters inside, which work in tandem to minimize stress on components. In the event of a converter failure, the remaining converter can provide full power to the amplifier.
- Each amplifier channel has two loudspeaker outputs which are separately supervised and protected, enabling the connection of interleaving loudspeaker strings within the same area. This prevents losing coverage of that area in the event of a shorted or interrupted loudspeaker line.
- A redundant system controller can be added and guarantees the highest safety for system operations.
