VOSK Monitoring & Control System
FOSM Complex
​
The FOSM (technical cabinet) includes all the elements necessary for the system to operate, as well as locations for additional VOSK units. This allows the integration of reserve VOSK units within the complex, thus adding a redundancy function. An unlimited number of VOSK units can be connected in a linear chain.
