ONNECTING THE SPEAKER UNITS
HelpyGSM comes with a built-in active speaker unit.
It is also possible to connect to the HelpyGSM:
-
up to 2 independent active speaker units
-
up to 2 passive speaker units (or cables with microphone) combined to the
integrated active speaker unit.
It makes HelpyGSM extremely flexible and allows to realize many different
types of installation.
Note:
an
active speaker unit
allows to realize an independent voice
point with dedicated pushbutton.
Note:
a passive speaker unit
must be connected to an active speaker
unit and allows to double it. The passive speaker unit can be
installed at max 6m distance from HelpyGSM (or from
another active speaker unit) by using a shielded cable.
Note:
in case of connection of active speaker units, the type of
installation must be defined (by setting parameters 63 and
73).
Connect the speaker units (beware of terminal polarity):
