APC devices are designed to filter out EMI (Electro Magnetic Interference) and RFI ( Radio Frequency Interference), which the X-10 technology appears to be when applied to the device.


The use of such technology does not adversely affect APC UPSs. However, a UPS or surge suppressor may absorb or filter out X-10 signals as UPSs and suppressors treat these signals as noise. The result, then, is that some X-10 equipment may cease to receive signals.

A possible solution is to install an X-10 isolator which prevents a UPS from filtering out these signals. One commercial solution is currently available from It is called a "noisy device filter".
