System devices

The central ward control unit Plus is the central control unit on a ward for the Gira nurse call system 834 Plus. It establishes the connection from the ward bus to the system bus (834 Plus LAN) and the system central control unit Plus. In small systems, it can also be used without a system central control unit.

The system central control unit Plus is the higher-level control unit for the Gira nurse call system 834 Plus. It connects to the central ward control units via an Ethernet line.

The Ethernet switch is used to connect system central control units, central ward control units and Gira Control 9 duty room terminals 834 Plus with one another. Thanks to its 24 V rated voltage, connection to an uninterruptible power supply (UPS) is also possible.

The power rectifiers are used to supply power to the Gira nurse call system 834 Plus. They are characterised by their closed design and contact-protected screw connections.

The impulse relays are needed to control the room lighting or the reading light via the patient hand-held device with intercom function.

The I/O module enables systems from other manufacturers to be integrated into the nurse call system 834 Plus via zero-voltage contacts and technical alarm messages to be issued. The flush-mounted I/O module has 8 inputs and 8 outputs.
