DUOX PLUS 24Vdc Filter (2 wires)
DUOX PLUS 24Vdc Filter Fermax 3289
Filter for 2-wire DUOX PLUS audio and video entry system. Although this new system now integrates the filter with the feeder (FER4825), there is also the possibility of installing the 3289 filter separately, along with the Fermax 4840 feeder; facilitating installation in an electrical equipment box, thanks to its small size.
Given the characteristics of the DUOX system, when the power and data go through the same cables, the source cannot be connected directly to the bus and that is why it must be previously connected to this filter. The filter prevents the power supply from disturbing the operation of the rest of the system signals, it also allows connecting more sources if necessary.
