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 Plug-in Filter between the power line and the monitor
to eliminate the effects.
