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 the manual, available at www.satel.eu
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 the malfunctioning of the device.
If the module is to comply with the requirements of the EN50131 standard for Grade 2, it must be installed in an additional enclosure that will enable it to meet the 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 the 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 cables 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.
Description of terminals
| +12V | – power input (12 VDC ±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| – programmable OC type outputs (disconnected from the common
ground / shorted to common ground).
O3…O4| – programmable relay outputs. When the module power is off, the
relays are open (NO). When the power is on, the output operates as defined by
the “Polarity” option (see full module manual).
AC| – input for supervision of AC voltage presence.
-
antenna connector (the antenna is delivered with the module).
-
SIM card slot.
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). -
APS connector for a SATEL power supply unit (e.g. APS-412).
-
LEDs indicating the module status.
-
RS-232 (TTL) port.

information on how to install the SIM card.
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. The antenna must not be
installed in parallel to low-voltage electrical wires, or it can affect the
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
- Connect the devices whose operation is to be monitored by the module to the input terminals.
- If the module is to be powered from the SATEL APS-15 or APS-30 power supply, you can connect to the AC input terminal the wire from the secondary winding of the transformer which supplies the AC voltage to the power supply (Fig. 2). This will enable the GPRS-A module to supervise the presence of AC voltage.
- 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 if the module is powered from SATEL APS-15 / APS-30 power supply unit.
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 the 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 and DS-T2 waterproof
temperature sensors. The DS-T1 sensors measure temperatures ranging from -35°C
to 60°C, while the DS-T2 from -40°C to 110°C. They are suitable for indoor
or outdoors mounting. The DS-T1 sensors can be secured to the mounting surface
with adhesives or screws. The DS-T2 sensors are designed for flush mounting
(they are 6 mm in diameter) The DS-T1 / DS-T2 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 a
power supply, or from a power supply unit with current limitations up to 4 A.
SATEL offers power supplies (e.g. APS-412), which can be connected to the APS
connector on the electronics board.
The required output current of the power supply is at least 250 mA.
-
Depending on the selected method of module power, 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 mm2, or rigid conductors with a cross-section of 1-2.5 mm2).
Never connect the power supply to the APS connector and terminals at the same time. -
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. Required program version: 2.0 (or newer). See the full manual for more information.
- update the module firmware (see the full manual of the module).
1.8 Installing the SIM card
- If a PIN code is required by the SIM card, use the GX Soft program to program the code.
- Power down the module.
- Insert the SIM card into its slot as shown on the enclosure.
- Power up the module. Logging the telephone into the cellular network may take a few minutes.
If the module is to send data via the cellular network, 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 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 it into a
mobile phone. Then, enter the PUK code.
