Additional accessories
The external unit uses
• 2-wire
cabling for systems with
1 audio external unit and max. 20 audio internal units.
• 3-wire
cabling for systems with
multiple audio external units or more than 20 audio internal
units.
• 6-wire
cabling in combination with
a camera
(see camera manual)
Also pay attention to the diameter of the conductors in the cable as it determines the maximum distance
that can be bridged between the power supply and the external unit. Double pairs can be used to bridge
larger distances.
Niko recommends the use of the following
cables
for installation of the external unit:
• Diameter 0.8mm (SVV, JYSTY, TVVF…): max. distance 250m
• Diameter 0.6mm (TPVF…): max. distance 150m
• Diameter 0.5mm (UTP, FTP, STP…): max. distance 100m
For a video system, always use a twisted pair cable (see camera manual)
