The signal transmission of high frequency pulses via the mains network can be affected by active or passive interferences. When used correctly, the filter/phase coupler will extensively suppress these interferences.
The signal blocking filter is designed to be installed at the input of the consumer unit breaker panels or fuse boxes. This allows X-10 signals to pass between different wiring circuits, but prevents them from leaving the household and interfering with X-10 equipment in nearby homes.

Best for apartments and X10 systems installed in close range.

For professional use! When installing consult an electrician.
