Marmitek FM10 Guide Utilisateur page 5

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 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. 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).

Congratulations on your purchase of the Marmitek X-10 Plug-in Filter FM10. This is a Plug-in
Filter to filter noise from TVs, photocopiers, motors, switched-mode supplies, etc. The FM10
is used to prevent the Marmitek X-10 PLC signals (Power Line Carrier) being absorbed by
equipment with a damping effect on these mains signals.

What is the reason for modules to switch on/off spontaneously?
It is possible that a Marmitek X-10 System is installed at one of your neighbours using the same
House Code. To solve this problem try to change the House Code of your system, or have FD10
Phase Coupler/Filter installed at your incoming mains.
