are connected to the power line. In a normal home situation this effect is negligible (the
Marmitek X-10 system is using active gain control to eliminate the effects). However, it
is possible that a particular 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 con-
nect 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. Hereby make your house Marmitek X-10 compatible for these
units. The FD10's will not only filter but will also couple the phases (please see 1).
