The Gira nurse call system is designed for operation in hospitals, care homes and other care organizations, but can also be used for doctor's offices and public sanitary installations. The special feature: the various functions of the Gira nurse call system can be integrated in the frames of the Standard 55, E2, Event, Esprit, E22 and F100 switch ranges. The nurse call system is therefore not only matched to the corresponding switch range, but in hospital and care applications the complete electrical installation can now be implemented in one and the same design.
