couple them with the use of a CAT 3000 active 3 phase coupler/
repeater (Art.No. 09304) and it is required if wall outlets and
lighting points are actually divided into several phases (several
groups is no problem for the Marmitek X-10 signal).
2.
It is possible that Marmitek X-10 signals are attenuated by devices
and lights which 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
Fl
uorescent 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
