device in your house is attenuating the signals so much that the range of
Marmitek X-10 signals is decreased significantly. When you have range
problems, it is wise to try to locate the device which is attenuating the
signals simply by unplugging devices from the power line, and testing the
differences in range for your Marmitek system. When e.g. your conclusion
is that e.g. your computer monitor is attenuating the signal, you can use a
FM10 Plug-in Filter between the power line and the monitor to eliminate
the effects.
Known devices which can cause attenuation are:
PC Monitors
PCs with heavy internal power supplies
Old Televisions
Copiers
Fluorescent Lights
Gas Discharge Lamps (Energy Saving Lamps)
3. Some (old) devices are able to disturb the signal by transmitting noise on
the power line. Because the Marmitek X-10 signals are transmitted on 120
kHz, only noise on or near this frequency will have influence on the range.
When you use a FM10 Filter to connect this device to the power line, the
noise will be filtered.
4. The Marmitek X-10 protocol has several mechanism to avoid modules to
be switched on or off by other sources than your Marmitek X-10 Controllers.
However, it is possible that the Marmitek X-10 signals are disturbed by e.g.
baby phones which are in TALK mode (continuous transmission). When
these kind of signals are present on the power line it is possible that the
Marmitek X-10 signals will not come through.
5. The mains do not stop at the front door of your home. Everything that is
attached to mains nearby your home can have influence on Marmitek X-10
signals (e.g. heavy machinery). If you think that your system is influenced by
devices out of your house, it is advisable to install FD10 Phase Coupler/Filter
on each phase entering the house. These filters will block signals coming
into or going out of your house, but will also match the impedance for the
mains. The FD10's will not only filter but will also couple the phases (please
see 1).
