CONNECTING THE TELEPHONE LINE
PSTN line or universal GSM gateway
 Connect the ground terminal (indicated by ), to a ground socket in
order to increase the telephone line protection.
 Connect the telephone line to terminal LTI.
GSM200-C module
 Please see also the GSM200-C User Manual.
 Connect the RJ45 connector (M in the picture at page 2 / I in the picture
at page 3) to the GSM200-C module by means of the supplied cable.

CONNECTING THE SPEAKER UNITS Page 7
CONNECTING THE SPEAKER UNITS
Helpy 2W-TL comes with a built-in speaker unit.
It is also possible to connect to the Helpy 2W-TL:
- up to 16 independent 2W speaker units by means of the 2-wire bus (4
units with direct power supply from the bus and 12 with separate power
supply)
- up to 2 passive speaker units (or cables with microphone) combined to the
built-in speaker unit.
Note: a 2W speaker unit allows to realize an independent voice
point with dedicated pushbutton and indicator lights.
Note: apassive speaker unit must be connected to the Helpy 2W-
TL’s built-in speaker unit or to another 2W speaker unit and
allows to double it. The passive speaker unit can be installed
at max. 6 m distance from Helpy 2W-TL (or from 2W speaker
unit) by using a shielded cable.
Each 2W speaker unit connected over the bus (the built-in speaker unit is
included) must have a unique ID. Speaker units with the same ID can not have
access to the bus and are not working.
Note: the identifier 01 must be assigned to the cabin speaker unit
(default is assigned to the Helpy 2W-TL built-in speaker unit).
If the 01 ID is assigned to a 2W speaker unit, the built-in
speaker unit automatically takes the ID 99 (it is possible to
assign a new ID to the built-in speaker unit through the code
73).
 Assign, using the DIP switch, an ID to each 2W speaker unit (see next
paragraph).
 Connect the speaker units (beware of terminal polarity):
