The main feature of the architecture of NANOVES is versatility, exchangeability of the devices which control its operation of this system such as SCU-8ZLCD, SCU-11Z, SCU-11ZLCD three types of Control Units that function in a redundant communication ring. Each CU is equipped with unique features so configurated as to execute Public Address & Voice Evacuation functions in any point of the system and in any type of the buildings optimally in terms of costs and equipment required. These Control Units may both perform the major function of system control and be a minor element of a local character. What is more, functions performed by central units which control the functioning of the system can be taken over by fireman microphone panels. This is an extremely flexible and scaled structure aimed at functional and cost optimization of construction of every project, including of the most complex ones.

A Control Unit is the main element of the system which receives an audio signal from sources and broadcasts it to the whole system. A Control Unit is a central unit managing all the remaining elements of the system and enabling flexible configuration of routes for audio signals from any source of signal to any outlet. Global switching of audio routes occurs on the basis of a programmable logic system as wall as Ethernet 1G network (UDP / IP, TCP / IP).

A Control Unit is controlled by SCUE-CPU processor card which task is to reproduce audio communications from a SD card and make them available locally and globally. This card exercises system functions (realization of scenarios) as well as control functions (verification of configuration cohesion). Each CPU card allows for simultaneous reproduction of eight messages.

Elements of the system operate with resolution of 48 kHz / 16 bit / 2 channels. Long distance communication between the devices is made by gigabit TCP/IP transmission over fiber. Thanks to double the number of fiber and cat5 ports the redundancy of connection is assured.
