information on how the product is integrated into a complete system can be found in the technical catalogue.
The external unit is a flush-mounted unit and as such has an ultra flat and elegant appearance. Depending on the type ordered, the external unit has 1 to 30

Additional accessories
The external unit is cabled with 2 wires for systems with 1 external unit and max. 20 internal units.
The external unit is cabled with 3 wires for systems with multiple external units or more than 20 internal units.
Also pay attention to the diameter of the conductors in the cable as it will determine the maximum distance that can be bridged between the power supply
and the external unit. To bridge greater distances, double pairs can be used.
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
