Voltage Surge Protection - Tunstall FlamencoIP Technical Manual

13. Voltage surge protection

The German standard DIN VDE 0834-1 regulates that all cables of the nurse call sys-
tem which are to emerge from the building shall be provided with voltage surge pro-
tection according to EN 50468 at the emerging point.
For the voltage surge protection you have especially to follow:
EN 61663-2: Lightning protection -Telecommunication lines - Part 2 Lines using me-
tallic conductors (IEC 61663-2:2001).
In the following the structure of the voltage surge protection is presented for cables

of the Flamenco nurse call system, which are laid between two buildings.

Note! For the described fine protection of the Flamenco nurse call system it is pro-
vided that a basic surge protection to absorb the higher energies has been com-
pleted according to the valid regulations. The installation of a fine protection would
be useless without this upstream protection.
The voltage surge protection has to be installed in the main building connection point.
This should be installed directly where the cables enter the building.

Note! To make sure a permanent protection of the Flamenco nurse call system,
the voltage surge protection devices have to be installed acc. to the manufacturer 's
specifications.
