The system central control unit Plus is the higher-level control unit for the Gira nurse call system 834 Plus in large systems. It connects to the central ward control units via an Ethernet line. As an option, the system central control unit Plus can be extended to include various software modules. This means that DECT telephone systems, VoIP systems, fire alarm centres and electrical speaker systems can be integrated into the system.
On a ward or in smaller facilities, the Gira nurse call system 834 Plus is managed via the central ward control unit Plus. It links all devices that are connected via the ward bus or the room bus to the system bus (834 Plus LAN). Up to 26 wards can be connected via the system central control unit Plus.
