Bosch PRAESENSA PRA-MPS3 Multifunction power supply, large
- Fully supervised DC‑power supply with integrated fail-safe redundancy
- Unique single 12 V battery backup solution
- Integrated 6‑port Ethernet switch on RJ45 and SFP
- General purpose control inputs and outputs
- Backup lifeline for connected amplifiers
This compact device combines multiple support functions to power and serve other PRAESENSA system devices. It can be used in a centralized system, but it is an enabler for decentralized system topologies with several smaller racks or cabinets located across the premises, to reduce loudspeaker cabling costs significantly. It provides DC‑power supply to connected amplifiers and peripherals from the mains, with a standards compliant charger for a single 12 V backup battery, saving on installation and battery maintenance costs. The integrated 6‑port Ethernet switch, with glass fiber support, facilitates easy interconnection of decentralized clusters of devices. Configurable, supervised control inputs and voltage‑free control outputs are available as interface to external equipment. Its OMNEO interface for control and fault reporting also provides an analog audio backup lifeline for the connected amplifiers.
Bosch PRAESENSA PRA-SCL System controller, large
- Full control of PRAESENSA devices and audio routing
- Built‑in supervised storage for messages and tone files
- Support for Dante audio input and output streams
- Open interface to third party applications
- IP‑networked on OMNEO for audio and control
The PRA-SCL is the most powerful version in a range of system controllers. The system controller manages all system related functions in a PRAESENSA Public Address and Voice Alarm system. It routes all audio connections between network-connected PRAESENSA audio sources and destinations. It supervises and plays back messages and tones, stored on its flash memory, either scheduled or manually started from a call station or PC. It manages the routing of background music streams, along with business calls and emergency calls, all based on priority level and zone occupancy. It collects all status information of connected system devices, manages the event logs and reports faults. The system controller is network‑connected via OMNEO and DC‑powered from a multifunction power supply with integrated battery backup, accommodating both centralized and decentralized system topologies. Connections to other devices in the system are made using the built‑in 5‑port switch, supporting RSTP. The built‑in web server allows for system configuration using a browser.
