BOSCH PRS-NCO-3 Wiring & Connection Methodology

The BOSCH PRS-NCO-3 utilizes specialized interfaces for various system integrations, ensuring secure and stable connections:

Network Connections: Utilizes proprietary Bosch Praesideo plastic optical fiber (POF) connectors. These connectors are arranged in a loop configuration to provide complete system redundancy.

Power Connections: Features a standard 3-pin IEC socket for AC mains power input, alongside dedicated screw terminal blocks for secure 48 VDC backup battery input.

Control Inputs and Outputs: Uses detachable screw-terminal blocks (Euro-style connectors), making it easy to wire logic inputs (e.g., from fire alarm panels) and relay outputs to external indicators.

Audio Line I/O: Configured with standard XLR and cinch (RCA) connectors for line/microphone inputs and line outputs, allowing easy integration with external media players, mixers, or recording devices.

BOSCH PRS-NCO-3 Key Product Advantages

Advanced Network Routing: Efficiently handles up to 28 simultaneous high-quality audio channels across a secure digital network.

Fail-Safe Reliability: Features dual optical network interfaces that support redundant loop topology, ensuring continuous operation even if a network fiber cable is broken.

Dual Power Redundancy: Automatically switches from AC mains to 48 VDC backup battery power in the event of a power failure, ensuring zero downtime for emergency communication.

Built-in Message Storage: Features internal flash memory for storing critical emergency messages, chime signals, and scheduled announcements.

Comprehensive Supervision: Monitors the entire system infrastructure including connected devices, network integrity, and internal functionalities, reporting faults in real-time.
