SIGNAL RANGE
Range of Marmitek X-10 signals over the Power Line
and how to increase the range.
The Marmitek X-10 System is based on power line
communication. The range of the Marmitek X-10 signals
very much depends on the local circumstances. On average
the range is a cable length of 80 meters.
If you have difficulties with the range of your
Marmitek X-10 signals, please pay attention to the
following facts:
1. When more than one phase is used for your electrical
system, it is necessary to couple these phases for the
Marmitek X-10 signals. For coupling you can use FD10
Phase Couplers/Filters. You only need to install a Phase
Coupler/Filter when your wall outlets and light switches
are divided over more than one phase (more than one
group is no problem). For bigger buildings or longer
distances we advice you to use an active repeater instead
of passive FD10’s.
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
