Page 4 CONNECTING THE TELEPHONE LINE
CONNECTING THE TELEPHONE LINE
The alarm system is ready for connection over the GSM line by the proprietary
GSM200-C.
It allows the connection of a PSTN line or an universal GSM gateway with the
optional PSTN-line board.
GSM200-C module
Please see also the GSM200-C User Manual.
Connect the RJ45 connector (D in the picture at page 2) to the GSM200-
C module by means of the supplied cable.
PSTN line or universal GSM gateway
Insert the optional PSTN-line board in the dedicated connectors (F in the
picture at page 2)
Connect the ground terminal (indicated by
), to a ground socket in
order to increase the telephone line protection.
Connect the PSTN line or the universal GSM gateway to terminal LTI.
CONNECTING THE SPEAKER UNITS Page 5
CONNECTING THE SPEAKER UNITS
It is possible to connect to the Helpy 2W-LCP up to 16 2W speaker units by
means of the 2-wire bus (4 speaker units with direct power supply from the bus
and 12 with separate power supply). A passive speaker unit can in addition be
connected to each 2W 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 a 2W speaker unit
and allows to double it. The passive speaker unit can be
installed at max. 6 m distance from the 2W speaker unit by
using a shielded cable.
Each 2W speaker unit connected over the bus must have a unique ID. Speaker
units with the same ID cannot have access to the bus and are not working.
Note:
the identifier 01 must be assigned to the cabin speaker unit.
Assign, using the DIP switch, an ID to each 2W speaker unit (see next
paragraph).
Connect the speaker units (beware of terminal polarity):
