• Public address and emergency sound system control unit
• Control and routing of 28 simultaneous audio channels
• Ethernet interface for configuration, control, diagnostics, and logging
• Digital storage for pre‑recorded messages
• EN 54‑16 and ISO 7240‑16 system certification

The network control unit is the heart of the Praesideo system. The unit routes up to 28 simultaneous audio channels, delivers power to the system, reports faults, and controls the system. Audio inputs can be announcements from call stations, background music, or local audio. The network control unit can be configured for the most complex public address systems. The configuration can be done comfortably and efficiently via a PC. The PC is only needed for configuration. The controller can operate independently of the PC. However, the controller can use a PC to display information on the system status using the software, supplied with the unit. The unit can be freestanding on a tabletop or mounted in a 19″ rack. The PRS‑NCO3 network controller needs PRS‑SW software version 4.0 or higher.

• Two current-limited network tap-offs
• Supports redundant network connection on main loop
• Can feed power from an external supply to the network
• Indicators for power and fault status

The network splitter is used in a network to provide two branches from the main cable run. It can use an external DC power supply, or it can use the power supply from the network controller. The unit automatically switches to the local power supply unit when it is connected to it, reducing the power drain on the main network. The network splitter can also function as a repeater, effectively extending the length of the main network another 50 meters.

• Serves multiple Call Station Clients and/or Telephone Interface Clients
• Controls multiple Network Controllers in extended systems
• Includes a license for a single Network Controller
• Controls user access with selectable rights per user

The PRS‑SWCS PC Call Server is a Windows service connected to one or more Praesideo network controllers via TCP/IP, using the Praesideo open interface. It is used in combination with one or more client applications, such as the PC Call Station Client and the PC Telephone Interface Client, handling all operational requests. The PRS‑SWCS PC Call Server is configured via an included PC Call Server Configuration Client, running on the same computer.

  Discussion Devices are connected in a daisy‑chain configuration to the Control Unit (CCSD‑CU or
  CCSD‑CURD) of a CCS 1000 D Digital Discussion System. Their plug‑and‑play functionality allows them
  to be conveniently connected to and removed from the system as required. A power down or restart of the system is not necessary, which ensures fast installation and reconfiguration times. Participants can take part in a discussion by speaking into the microphone and listening to proceedings through the built‑in loudspeaker or (optional) headphones.
