TYPES OF WIRES USED
The two-wire bus is NOT polarised. Only use the wire of the type shown in the following table according to
the distance and the type of indoor stations used. Use the dedicated wire Ref. 1082/90 for optimal system
performance.

(*) Use of a twisted wire is recommended to improve system effi ciency and increase interference immunity.
The common segments running in the same connection tube to the riser column and the video door phone
must be considered when calculating the maximum distance and must be max. 2m each if wires without
sheath are used.

The 2GO! system elements must be interconnected in a genuine transmission network. For this reason, each
75m
network section must be adapted to the wire impedance for correct operation. Consider the following:
• Only use the type of wire shown in the previous chapter.
75m
• The minimum twisting radius must not be less than 10 times the external diameter of the wire
(approximately 7cm) to prevent altering characteristics.
• Remove the sheath for the length needed to separate the pair in the two-wire line only.
75m
• Do not add electrical nodes to connect the devices. Use the device terminals only. Fit a Ref. 1082/51
video distributor to connect an extension indoor unit to a riser column that does not cross the apartment:
