GSM/GPRS Alarm Communicators
12. Following the arrow, insert the SIM-CARD [8] face down in the SIM holder [6] (see Figure 1).

The SIM-CARD PIN must be disabled before the card is inserted into the transmitter.

It is recommended that you disable call forwarding on your SIM card.
13. Make sure that all the green LEDs flash when the product is switched on; this means the Communicator is in its initialisation phase.
14. Checking Signal Strenght :
– make sure that at least one of the green LEDs remains lit; all green LEDs lit indicates optimal coverage;
– if the green LEDs are not illuminated, the signal strength is TOO WEAK; for the signal to be of an acceptable level, at
least one green LED must be lit.
15. Close the communicator: fasten the lower side of the cover [18] to the base [17] then press the upper edge of the base
to close the cover; fix the cover in place using screws [25].
Connect power circuit and the telephone line only after the cabinet has been secured to the building or
structure and has been connected to the protective earth ground of the building.

Before inserting or removing the SIM card, please ensure the unit is powered down.
CONNECTING THE DEVICE
This section describes the terminals and auxiliary connections. Figure 3 shows a typical wiring diagram.

The Open Collector current may not exceed 100 mA. If necessary, commutate greater loads using switches.
Auxiliary connections
The auxiliary connections are not necessary for the Communicator operation, but they maximize the versatility of this
device. These connections are described in the following paragraph.
Tamper - The connection of the MAXIASNC tamper switch (optional) allows you to detect the Communicator cover opens.
The tamper switch wires can be connected as follow.
— To the panel tamper line or a different 24h zone. Read the panel instructions for more information.
— To terminals [ T3 ] and [
M
] of the GS3125, to send a SMS and/or Voice message, to one or more telephone numbers,
when the Communicator cover is removed.
The second solution requires to program the Communicator by the GS3100 Series Console, as indicated in the Programming
the device->Optional Tamper Programming section. After connecting the MAXIASNC tamper switch and programming
the Communicator, close the cover and power up. After the initialization of the Communicator, open the cover and check that
the SMS and/or Voice message has been sent to the programmed telephone numbers.

Power supplied by the control unit or by the external power supply (optional), at a level between 10 and 27.6 Vdc,
make sure that this is protected and operating at a limited current; Limited Power Source (LPS) in conformity
with EN 60950-1:2006 standard.
!
To connect the supply use wires with a maximum 2 mt length and 0.75mm² cross-section. For shorter wires
use suitable cross-sections.

T1
Open Collector outputs: These outputs are activated by
breakdown events on the PSTN line (T1) or on the GSM
network (T2).
Programmable terminals: These terminals can be
programmed as;
– Open collector outputs (default setting): These outputs
may be activated either by programmed events (automatic
activation), or by a command sent via SMS, or through
caller recognition (remote activation); please refer to the
“Output activation” section for further information. The
maximum current available at each OC output is 100 mA.
– Input lines: When these inputs receive alarm signals,
they can activate the SMS and telephone dialer functions
(please refer to the “SMS dialer” and “Voice dialer”
sections).
