This manual describes how the GPRS-A module should be installed. For further information
related to the module, including its configuration and operation, please refer to the full version
of manual, available at www.satel.eu
1. GPRS-A module installation
Disconnect power before making any electrical connections.
It is not advisable to power up the module if the antenna is not connected.
The installation to which the module is to be connected should be provided
with:
2-pole disconnector,
short-circuit protection with a 16 A time delay circuit breaker.
The GPRS-A module should be installed indoors, in spaces with normal air humidity. When
selecting the mounting location, remember that thick masonry walls, metal partitions, etc. will
reduce the range of radio signal. It is not advisable to install the module in close vicinity to
electrical installations, because this can result in malfunctioning of the device.
If the module is to comply with requirements of the EN50131 standard for Grade 2, it
must be installed in an additional enclosure that will enable it to meet requirements of
the tamper standards (e.g. in the SATEL OPU-3 or OPU-4 enclosure).
1.1 Preparing the cabling
Run the cables to be used for connecting the module with other devices to the module
installation place. Do not lay the cables in immediate vicinity of the low-voltage electrical
network wires, especially those used for supplying the high-power equipment (such as
electric motors).
It is recommended that unshielded non-twisted cable to be used.
1.2 Installation of the module
The module enclosure base makes it possible to secure the module to the mounting surface
by using e.g. a cable tie or angle hooks.

Inserting the SIM card into its slot before programming the card PIN code in the
module is not recommended (if the card requires entering the PIN code).

Description of terminals
+12V – power input (12 V DC ±15%).
COM – common ground.
RING, TIP – terminals for connecting the control panel telephone communicator.
S1…S3 – 1-Wire bus (1-Wire digital temperature sensors can be connected to the bus):
S1 – common ground,
S2 – data,
S3 – power supply.
I1…I8 – inputs. They can be programmed as digital (NC or NO type) or analog ones.
O1...O2 – OC type outputs (shorted to common ground when in active state).
O3...O4 – NO type relay outputs (normally open).
AC – input for supervision of AC voltage presence.
1.2.1 Antenna
The GPRS-A module is delivered with an antenna. The antenna can be replaced with
another antenna mounted on the enclosure or at some distance from it.
Using the antenna mounted at some distance from the enclosure is recommended wherever
thick masonry walls, metal partitions etc. may decrease the range of radio signal at the
module installation place.

SATEL GPRS-A 3
The antenna must not be installed in parallel to low-voltage electrical wires, or it can affect
performance of the antenna.
1.3 Connecting the alarm control panel
Connect the control panel telephone communicator to the TIP and RING terminals.
1.4 Connecting the devices to the inputs and outputs
1. Connect the devices whose operation is to be monitored by the module to the input
terminals.
2. If the module is to monitor the presence of AC voltage fed into the device from which the
module is supplied, the wire from the secondary winding of transformer from which that
device is supplied is to be connected to the AC input terminal (see Fig. 2).
3. Connect the devices which are to be controlled by the module to the terminals of outputs.
Fig. 2. Example of connecting supply and monitoring AC voltage presence.
1.5 Connecting the digital temperature sensors (1-Wire)
You can connect up to 8 digital temperature sensors to the 1-Wire bus. The length of wires
should not exceed 30 meters. If several sensors are to be connected to the bus, it is
recommended that you use the distribution box module (MZ-2 or MZ-3).
SATEL's product offering includes the DS-T1 waterproof temperature sensors. They make it
possible to measure temperatures ranging from -35°C to 60°C. They are designed for surface
mounting indoors or outdoors. To secure them to the mounting surface, you may use
adhesives or screws. The DS-T1 sensor wires are to be connected to the bus terminals in the
following manner:
black wire – terminal S1 (common ground),
green wire – terminal S2 (data),
white wire – terminal S3 (power).

1.6 Connecting the power supply and starting the module
The module may be powered from the control panel, from an expander with power supply, or
from a power supply unit with current limitation up to 3 A. SATEL offers power supplies (e.g.
APS-612), which can be connected to the APS connector on the electronics board.
The required output current of power supply is at least 250 mA.
1. Depending on the selected method of module powering, connect the power supply unit to
the APS connector or connect the power leads to the +12V and COM terminals (use
flexible conductors with a cross-section of 0.5-0.75 mm
2
, or rigid conductors with a cross-
section of 1-2.5 mm
2
).
Never connect power supply to APS connector and terminals at the same time.
2. Power up the module. The module will start up.
1.7 Connecting the computer to the module
Connect the computer to the module RS-232 (TTL) port. To make the connection, use the
USB-RS converter offered by SATEL. Having connected the computer to the module, you
can:
configure the module by using the GX Soft program. You can download the GX Soft
program from the www.satel.eu website. It can be installed on computers with WINDOWS
VISTA/7/8/10 operating system. See full manual for more information.
update the module firmware (see full manual of the module).
1.8 Installing the SIM card
1. If PIN code is required by the SIM card, use the GX Soft program to program the code.
2. Power down the module.
3. Insert the SIM card into its slot as shown on the enclosure.
4. Power up the module. Logging the telephone into the GSM network may take a few
minutes.
If the module is to send data in GPRS technology, it is recommended that you use SIM
cards with a dedicated tariff plan for M2M (machine-to-machine) communication.
If the programmed PIN code is invalid, the module will report a trouble. Programming
a correct PIN code will clear the trouble.

Restarting the module with a wrongly programmed PIN code three times will block the
SIM card. To unblock the SIM card, remove it and insert into a mobile phone. Then,
enter the PUK code.
