Audio system installation
In the audio system, it is possible to establish voice connection between the panel and handset in flat. To
make the handsets connection, use any two-conductor cable of conductor cross-section >0.5 mm

.
Handsets can be connected using any method maintaining the polarization of conductors. Both, star-type
connection to the bus or from handset to handset, will provide correct operation of the system. It is not
recommended to connect the handsets using a cable of length exceeding 200 m. However, if this is
necessary, it is possible, but one must use cables of larger cross-section (e.g. twice as large). Handsets are
installed according to the manufacturer's installation manual. Connect paying attention to correct setting of
physical address (number in decoder) and correct (correct polarization) connection to terminals LU and
GND in the panel (LU - signal, GND - ground).
