General NOTES about DUOX WIRING
DUOX is characterized by its fl exibility in the use of different cable
types. For ideal operation, it is recommended to use 2x1mm²
parallel cable. (Ref. 5925).
It is preferable to avoid:
1. Doubling cables (joining 2 pairs to increase section).
2. Using different cable type or changing the section throughout
the installation.
3. Loose wires (electrical installation wiring not within its hose).
4. Different length cables.
As Duox is a system designed for replacement, it works with the
existing wiring in older installations:
• Parallel (black-red). 0.2mm² minimum
• UTP CAT-5
• Hose with several wires (for example, 5 wires, 6 wires...etc.)
• 4+N Installations
Naturally, we cannot access an installation offering the same
features and fl exibility of installation when the cable section is
0.2mm² as when it is 1mm².
