GSM/GPRS Alarm Communicators
Description
This Communicator manages SMS and Central Station transmissions (SMS transmission for the GS3125 series only) and can
simulate the land line in the event of trouble (land line down) or even substitute the land line completely in areas where the GSM
service is provided and where the land line is not available.It has capability of communicating alarm signals via the GPRS data
network. This capability enables a fast reliable path to central stations equipped with a Sur-Gard System III or System II receiver.
The performance of this Communicator depends greatly on GSM Network coverage, therefore, it should not be mounted without
first performing placement tests of the antenna to determine the best location for reception (at least 1 green LED should remain lit).
The GS3105 Communicators series have 3 Outputs, one of which may be activated/deactivated remotely, while the other
2 may be used to indicate: problems on the PSTN telephone line; problems on the GSM network.
The GS3125 Communicators series, on the other hand, have 3 terminals which can be programmed as follows:
– Outputs (default setting) which can be activated/deactivated remotely, or used to provide status indications (problems
on the PSTN telephone line; problems on the GSM network; Supervision Message Missing; Fail To Comunicate).
– Input lines for speech dialer and SMS dialer activation; these functions can also be used to transmit status indications.
Due to the characteristics of GSM Networks, this Communicator can activate only as intended and cannot be used as a
modem for fax/data transmissions or for teleservice operations.
IDENTIFICATION OF PARTS
The numbers in square brackets [ ] in this manual refer to the main parts of this Communicator (see Fig. 1) described in this section.
INSTALLING THE DEVICE
Do not route any wiring over circuit boards.
This Communicator shall be installed by qualified SERVICE PERSONS only, in the shelter of a safe and dry
site, away from radio-transmitting equipment.
Test the GSM Network reception before mounting this Communicator in the proposed placement.
GS3105-K or GS3125-K
This Communicator consists of a board intended to be placed inside the intrusion panel, preferably having
a metal box, and of an antenna that is connected to the board by a coaxial cable. During normal working,
those elements (board, antenna and cable) could generate radiated electromagnetic fields and, if there are
any electronic devices not sufficiently immune to such fields nearby, there might occur certain unwanted
interactions. For this reason it is advised to place the board as far away as possible from such susceptible
devices and to put the antenna on the external surface of the metal box or far away from it by means of the
bracket. It is advised to keep inside of the panel metal box the minimum coaxial cable part and to place any
extra length on the outside of the metal box.
1. Loosen the screws and remove the control panel cover.
2. Establish an area inside the metal casing which can be used to hold the board, including the wiring.
3. Position the 4 adhesive plastic supports [14] on the base of the metal casing, then fit the holes [7] on the Electronic board
into the adhesive plastic supports, as illustrated in Figure 2.
4. Fit the antenna [1] to the outside of the casing.
4a. Position the antenna [1] on top of the metal casing (Fig. 2) so that the magnetic base [2] sticks to the surface. Feed the
antenna cable through the cable feed opening in the metal casing. If necessary it is possible to use the metal bracket
[13], (Fig.2a).
Fix the metal bracket [13] to a suitable support using the holes provided [12]. Position the antenna [1] on top of the metal
casing - see Fig. 2a - so that the magnetic base [2] sticks to the surface. Feed the antenna cable through the hole [11]
in the metal bracket [13].
5. Connect the wire [3] to the GSM antenna connector [4].
6. Complete the connections on the terminal blocks [10].
7. Following the arrow, insert the SIM-CARD [8] face down in the SIM holder [6] (see Figure 1).

It is recommended that you disable call forwarding on your SIM card.
8. Make sure that all the green LEDs flash when the product is switched on; this means the Communicator is in its
initialisation phase.
