Preliminary notes: Flamenco
General
The Flamenco system is a universally applicable communication platform meeting all de‐
mands put forth to modern care organisations in hospitals, nursing homes and comparable
institutions. In an ideal manner, Flamenco combines a nurse call system with the possibilities
of modern telecommunication and intelligent data networking. Based on self-sufficient tech‐
nology with intelligent network solutions, the Flamenco solution provides for exceptional func‐
tional reliability. The unique separation of physical wiring and organisational combination of
rooms allows for maximum freedom for the system layout and as such for any later use or
expansion. Excellent speech quality, devices and components suitable for everyday use and
simple handling are foremost features which ensure the efficient support of patients and staff
in daily nursing routines.
The peripheral components, such as corridor displays and loudspeakers can be used by
other systems, too. Flamenco has been prepared with the appropriate interfaces to connect
or integrate other make installations.
Standards
The nurse call system complies with DIN VDE 0834 Part 1 and 2, including the standards
which are referred to in this standard.
System structure
The system features a hierarchic structure and it is designed and arranged to the principle
of a bus line. The intelligent room bus RAN combines all room-related devices, and in itself
it is a fully functional entity. The individual devices communicate among themselves and con‐
stitute the basis for the nurse call system. Intelligence is integrated in all devices, and as such
even call switch and room lamp can process and display incoming messages. There is no
need for an overhead control arrangement for the rooms. The installation in the room itself
can be realised as bus, star or mesh.
The room network is the basis, and the next hierarchic level is a group bus, the OSYnet. It
links all users of a physical group. The central control, i.e. the OSI-ControlCenter, virtually
serves as the hub for all OSYnet connections, and coordination is effected from this central
unit. For larger projects, several OSY-ControlCenters are linked in a joint network. To provide
for even higher functional safety and reliability, the integration of one or more de-centrally op‐
erating OSYnet-SafetyControllers into the system structure can be realised.
The structured system topology, combined with automatic fault detection, provides for an ex‐
ceptionally high functional safety and reliability in the whole system.
