X10 PRO 5 AMP Plug-in Noise Filter - XPPF
For isolating electrical appliances that generate noise pollution on the powerline, preventing X10 command signals from getting through to modules. This filter has a tuned circuit designed for peak supression of line noise at frequencies which can interfere with X10 signal transmissions. Rated at 120 VAC, 5A.
Electrical devices such as TV, VCR, stereo, low voltage power supplies, computers, monitors and power/surge protection strips all have a tendency to “dump” electrical noise on the power lines.
Because line carrier products such as X10 use the power lines as a communications path they are susceptible to interference. When noise is placed on the power lines it can attenuate, corrupt and/or block the signals being transmitted or received throughout the entire house.
Typically, line noise will cause intermittent operation of the receivers. An example would be if you can turn on a light from a transmitter but cannot turn it off or dim it from the transmitter or you can turn off a receiver but cannot turn it on. The noisy device does not even have to be turned on, because a TV or computer still have their power supplies on the power line when they are turned off.
Noise on the power line is solvable with the XPPF LINE FILTER. The easiest way to pinpoint the noise source is to shut off each circuit breaker one at a time (except, of course the breakers that the controller and the non-responsive module are plugged into) and try the controller after each shutoff. When the module begins to work, you have isolated which breaker circuit the interference is coming from. Reset the breakers and systematically unplug each device on that last breaker circuit (TV, VCR, computer or low voltage lighting power supply) trying the controller after unplugging each one. When the problem module starts working upon unplugging a device, then you have detected an offending device.
The XPPF is plugged into the wall were the offending device was plugged in and the device is plugged into the XPPF. The X10 signal will now pass freely through the electrical system without the noise, blocked by the XPPF, passing onto the power line.
Note: make sure that you do not exceed the 5A load rating.
For loads greater than 5 Amps, or for hardwired applications, use the 20 Amp XPF WIRE-IN NOISE FILTER
Trouble with some modules not working may indicate you also have a line phase problem. It wouldn't hurt to also install a phase coupler. CLICK HERECLICK HERE TO SEE MORE X10 DEVICES
