• Redundant network connection
• Indicators for power and fault status
• Two supervised control inputs
• Can use a local power supply

Most of the Praesideo system units have plastic fiber optic interfaces. Plastic fiber is used to interconnect nodes which are less than 50 meters apart. For distances of more than 50 meters, glass fiber optic cable is used. A fiber interface converts from plastic to glass fiber, and vice versa. The fiber interfaces have a power supply input to provide power to remote network sections, and two control inputs. The control inputs can pass on supervision information about the power supply connected to the fiber interface.

• 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.

• Call station with soft touch button for PAVIRO system
• 15 freely programmable buttons
• Customization via built-in display and keys
• Provision for installing emergency button and key switch
• EN 54-16 system certification

The PVA-15CST is a call station for the PAVIRO system.
As standard, the call station has a gooseneck microphone with pop shield and permanent monitoring, a total of 20 buttons, an illuminated LC display, and an integrated loudspeaker. The call station can be modified to suit the user’s requirements by connecting up to five PVA-20CSE call station extensions, each with 20 customizable selection buttons.

The Control Unit is the main component of the CCS 1000 D Digital Discussion System. It supplies DC power to all connected Discussion Devices (CCSD‑DS/ CCSD‑DL) and monitors and controls the discussion system

• Plug-and-play functionality for quick and easy connection of up to 80 Discussion Devices
• Intuitive web browser interface control for advanced configuration and control

• Built‑in MP3 recorder with internal memory and USB recording

• Built‑in Digital Acoustic Feedback Suppression (DAFS) for ensuring superior speech intelligibility

• On-board support for automatic HD camera control
• CCSD-CURD Control unit with recorder and DAFS Pakistan | Islamabad | Lahore | Karachi

• Unique patent pending possible-to-speak indicator
• Plug and play functionality for ensuring fast installation and reconfiguration times
