- Up to 63 interconnected Central Units. In this case the aforementioned access points will amount to 31
per Central Unit.
- Up to 1022 Users per Central Unit:
Registration of incidents.
- Management of access restrictions based on areas (permitted access areas) and time periods

The MDS Digital System allows the system to be programmed solely as anAccess Control system.
- Intercommunication: Up to 999 audio panels (using panel decoders) to allow 1 or 2 button intercommunication
per central unit (calls to guard unit and emergency calls).
- Security: alarm management (up to 999 sensor inputs per central unit - 10 groups - using sensor decoders),
panic button in residential terminals to alert the guard, etc.
- Automation: lift control, management of up to 999 relay outputs and 999 sensor inputs (using decoders) per
central unit and management of time planner, etc.
- System programming and management software for PC (local and remote).
e) Number of buses (cabling).
- AUDIO only:
- Panel Bus: 4 wires and shielded twisted pair.
- Central interconnection bus (FXL network): 4 wires and shielded twisted pair.
- Decoder Bus: 4 wires and shielded twisted pair.
- AUDIO + VIDEO:
- Panel Bus: 7 wires and shielded twisted pair + coax.
- Central interconnection bus (FXL network): 4 wires and shielded twisted pair + coax.
- Decoder Bus + Video Distributor: 6 wires and shielded twisted pair + coax.
