- The use in other non-conventional installations:
• Proper operations is only guaranteed with a direct connection to the public telephone
network via copper wire.
• Even though Fermax´s telephone interface performs just like a conventional analogue
telephone, it may not operate correctly when connected to emulated phone lines over
fi ber optics or other analog technologies.
- The use on telephone switchboards:
• This interface may be incompatible with some types of telephone switchboards (ask the
switchboard manufacturer).

INSTALLATION DIAGRAMS

In order to obtain optimal performance of the Telephone Interface and minimise external
interferences that may be produced (network noise, radio electric interferences... etc.) we
recommend:
- On 4+N installations you can not share the street panel's power when AC. The VDS can
be powered by the bus.
- The telephone pair and electronic entry panel cables transport audio signals that are sensitive
to interferences, so we recommend not placing it near noise made from motors or industrial
machinery or electric wiring.
