Product Details:

Our firm is involved in manufacturing and supplying a huge range of PRS-NCO3 Praesideo Network Controller.

Features:

• The new PRS-NCO3 provides the same functionality as the PRS-NCO-B and runs with Praesideo Software Release 4.00.
• It has a faster processor, more memory, an output to power indicators and an internal buzzer for fault/alarm notification.
• The PRS-NCO3 must be used with Praesideo software version 4.00 or higher.
• The PRS-NCO3 cannot downgrade to a software version 3.x.
• The PRS-NCO-B can only be used with software releases 3.xx, not with software version 4.00.
• The PC Call Server is able to control PRS-NCO-B based sub-systems in combination with PRS-NCO3 based sub-systems.
• In this case, the software release of the PC Call Server should be the same as the software release of the PRS-NCO-B.

Product Details:

The LBB 4401/00 Network Controller unit is the heart of the Praesideo system. The unit is delivering power to the system (except for power amplifiers), fault reporting and controlling of the system. The audio inputs can be announcements from call stations, background music or local audio inputs. The network control unit can be configured for any complex public address configuration via the PC. The PC need not be connected permanently to the unit as it works independently from the PC. If a PC is connected to the network controller unit, all status changes in the system can be displayed through the configuration and diagnostic & logging software, supplied with the unit.

Features:

• Public address and emergency control unit
• Fully digital
• Ethernet interface for configuration and diagnostic & logging functions
• Digital message storage
• IEC60849 Certified

Functions:

• The network controller has 4 analogue audio inputs. Of these, 2 are selectable between microphone and line. The other 2 inputs are fixed as line inputs.
• The 8 control inputs are freely programmable for system actions, and priorities can be assigned to these inputs.
• The network controller has 4 analogue audio line outputs.
• The network controller has 5 control outputs of which three are programmable for faults or calls, and two are used to connect visual and audible fault indicators.
• The microphone/line inputs can be used as call inputs if they are programmed conditionally to any control inputs.

Product Details:

CobraNet is a registered trademark of Peak Audio, a Division of Cirrus Logic, Inc. The Cobra Lbb 4404/00 Cobra Net Interface can insert up to four audio channels from Cobra Net into the Praesideo system and up to four audio channels from Praesideo into a CobraNet network. Cobra Net, developed by Peak Audio, is a network protocol for real-time uncompressed digital audio distribution over industry standard 100Base-T Ethernet networks. CobraNet audio channels can be configured as inputs to Praesideo, where they can be routed permanently or conditionally to any of the zones or audio outputs. The routing conditions are configured using the configuration software. Praesideo calls and background music (BGM) sources can be routed to CobraNet channels. Digital audio data is directly converted between Praesideo and CobraNet, with no other audio processing than sample rate conversion. Control inputs and outputs are provided for external interfacing.

Product Details:

The fibre interface is used in a network to LBB 4414/00 Fiber Interface convert from glass fibre optic cable to plastic fibre optic cable and vice versa. This unit supports the redundant wiring topology. The unit can be provided with an external DC supply or it can use the supply from the network controller. The unit is automatically powered from the local supply if connected. 

Features:

• Redundant network connection
• Power ‘ON’ indication
• 2 supervised control inputs
• Error indication
• Possibility to connect a local power supply
• Certifications and Approvals
