X10 PRO In-Line Noise Reducer (XPNR)

If your X10 modules aren't responding properly due to noise from other electronics on the power line, install the X10 PRO In-Line Noise Reducer. The noise reducer attenuates power line signals above and below the X10 120KHz operating frequency, allowing X10 signals to pass through, while removing others. The In-Line Noise Reducer is a line filter with two wires that connect to the AC line between the AC hot and AC neutral wires. It can be installed at the noise-generating device (recommended), inside an electrical outlet, or at the circuit breaker. For especially problematic noise, you can install multiple reducers in different locations. The noise reducer attenuates signals by shorting the non-X10 power line signals to AC neutral. X10 signals can then pass freely throughout your home's electrical system without interference from noise generated by other devices. The reducer is rated for 120/240 VAC devices, but if your noisy device is 220/240 VAC, you can wire one Noise Reducer onto each of the AC hot leads to achieve the same results. NOTE: The In-Line Noise Reducer is typically used only when other noise reducing options, such as the XPPF or XPF Filter(s), have failed to improve X10 performance sufficiently. It can be used in any combination with the XPPF or XPF Filter(s) in hard-to-filter noise environments.
