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 interfering with 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 interfering with the
signals simply by unplugging devices from the power line, and testing the differences in
range for your Marmitek system. When e.g. your computer monitor is interfering with
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 interference are: PC Monitors, PC's
with heavy internal power supplies, Old Televisions, Xerox Copiers, Fluorescent Lights,
Gas Discharge Lamps (Energy Saving Lamps)
3.
Some (old) devices can also interfere with 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).
