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:

a passive 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):

In case of passive speaker units without built-in pushbutton it is possible to use
voltage free contact pushbuttons (NO or NC).

 Connect, following the diagram shown below, the external pushbutton.

2W speaker unit pushbuttons

It is possible to connect external pushbuttons (voltage free contact pushbuttons
or powered pushbuttons) to 2W speaker units without built-in pushbutton.

 Connect, following one of the diagrams shown below, the external

pushbutton to the 2W speaker unit.
