The ‘MDS/BUS2 decoder’ acts as an interface between the BUS2 system and the MDS system, enabling the connection
between the MDS reception and MDS panels in BUS2 systems, whilst extending the range of services offered by the
BUS2 system: locked entrances with multiple general MDS access points, central receptions, etc.
For more information on the combination of MDS and BUS2 systems, please consult the ‘MDS/BUS2 Technical Manual’.
