Telecom Module – E062
The Galaxy Telecom module is an optional add-on to the existing Galaxy product range. It is a highly intelligent
and compact module, combining both digital communication capabilities and remote servicing facilities.
The Telecom Module is connected to the RS485 communication line 1 (AB line) on the Galaxy control panels.
This can be connected in addition to the on-board Telecom module.
As a digital communicator (digicom), the Telecom Module transmits alarm signals using the selected format;
the factory default setting is DTMF (Dual Tone Multiple Frequency). As a remote servicer the Telecom
Module can be used, in conjunction with remote servicing software, to remotely access the Galaxy control
panel, allowing copying and overwriting of the program and on-line servicing.

Connection to the PSTN
The TelecommunicationsNetwork Voltage (TNV) port (Line A and B, JP8) on the Module must be perma-
nently connected (hardwired) to the Public Switched Telephone Network (PSTN) via a BT Master Socket.
Note: If the BT Master Socket is the newer type (NTE5), then the connection can be carried out by an
installation engineer. If the BT Master Socket is not an NTE5, then the connection must be made by
a network operator.
Programming the Telecom Module
The Telecom Module is programmed from the Galaxy control panel using menu option
56 - Communucations.
