2.3 - « Wired mode » installation
In accordance with the model, 100-
240VAC ±10% 50/60 Hz or 24 VDC,
connect the appropriate power supply on
the terminal strip (2).
As the device is a class II device,
there is no earth connection.
The cable must be attached (point 4) in
such a way as to place no stress on the
connection terminals.
In « wired mode » (dip switch 2 in the
OFF position) the power supply of the
Melodys is what controls the ringing
programmed by the master clock. The
melody selected in the Melodys is played whenever the circuit is closed by the master
clock.
If a 230V bell system has more than five sounders, use a contactor*, see the above
illustration.
* e.g. type Merlin Gerin reference 15373.
If a 24V bell system has many sounders, verify that the voltage does not drop below
the threshold (24V-10%). The section of the line should be fitted to its consumption
and length.

Important notes:
1 – The distance can be doubled by limiting the volume to 7.
2 – These distance limitations concern only one Melodys line; but it is possible to
install several lines in parallel.
