New network controller PRS-NCO-B released for the replacement of the previous model LBB4401/00.
The network controller is the core of the system Bosch Praesideo. The device controls up to 28 audio channels, delivers power to the system, reports faults, and controls the system. The audio inputs can be announcements from the stations transmission of announcements, background music or local audio signals. The network controller can be configured for use in the most demanding voice messaging systems. Setting can conveniently and effectively be performed from the PC. PC only required for configuration. The controller can operate independently from the PC. However, the controller can use a PC with supplied software to display information about the system state, the Device can be placed on the surface of the Desk or mounted in a 19-inch rack.

Function:

Connection:

The network controller has four analog audio input. Two of them have a choice between microphone input and line input. Two other entrances noted as linear. MIC/line inputs can be used as inputs in alerts, if they are programmed depending on any of the eight control inputs, which, in turn, are freely programmable for system actions, with freely programmable priorities.
The controller has four analog audio line output with selectable signal monitoring the 20 kHz each. Three outputs are programmable for faults or calls, the other two are used to connect visual and audible fault indicators.

Operation:

All settings of the network controller are performed with a PC using the supplied software, with which you can efficiently and easily configure the controller and also obtain information about the current status of the running system. After completing the settings, the controller can operate without a connected PC. The front panel has a LCD display capacity 2 lines, 16 characters, as well as rotating the knob to move through menus and select items. Address information, versions, manifestations of faults and the monitor can be obtained on the display using the control knob. The network controller can control up to 60 nodes. Nodes include equipment such as power amplifiers, audiocassette, station announcements, sets of transmission stations ads, etc.
In accordance with the requirements for warning systems in the network controller auto messaging. The controller has a built-in replaceable compact flash memory card that complies with the requirements for storage of audio messages. Can be played at once four messages. For storing messages being monitored. Audio messages (for example, a few wav files) can be downloaded from a PC via the Ethernet link. The controller also stores a variety of audio signals, test signals and alarm signals to which access can be made from any station the transmission of ad or control input for announcement or alarm broadcast. Internal clocks allow the network controller to automatically perform certain actions, for example, to play the scheduled announcements or changing the volume of the background music during working hours. It has extensive audio processing on the audio inputs and audio outputs. Parametric correction, control and amplification can be easily adjusted using the configuration program. For monitoring audio channels has a headset Jack.

Safety:

The network controller of the Praesideo public address system supports redundant network wiring. It can be connected to a branched network or redundant loop. The system can handle 256 priorities for calls from different areas, which satisfies the requirements of the most complex system voice alarm.
The controller monitors the status of all equipment in the system, reports status changes and stores the last 200 fault messages in the system. This monitoring is carried out throughout the system, from microphone stations transmit the ads to the speaker. Tracked all cases of open circuit or short circuit in the external cables connected to the control inputs. There is an internally generated control signal for monitoring audio inputs. The controller can be operated from the mains or from the battery backup 48 V, while switching between power modes takes place automatically. It can control both power supplies.
