3. Typical module applications
The extended functionality of GPRS-A LTE module enables it to be used for a variety of
applications. This section presents typical examples of its application. Some of them are
capable of being combined with one other.
3.1 Supervision / control of devices
Fig. 1. Module supervising operation of the devices connected to inputs and controlling
operation of the devices connected to outputs.
Changing the input state / exceeding the defined threshold limit value may result in:
sending event code to the monitoring station (reporting GPRS/LTE or SMS),
notification (messaging) about the event by means of SMS, push or CLIP.
The inputs can be blocked locally (by means of one of the module inputs or the GX Soft
program) or remotely (by means of SMS messages, the GX Soft program or the GX Control
application).
1-Wire sensors can be blocked from GX Soft program or GX Control app.
The devices connected to the module outputs can be controlled locally (by means of module
inputs or the GX Soft program) or remotely (by means of SMS messages, CLIP, the GX Soft
program or the GX Control application).

6 GPRS-A LTE SATEL
3.2 Simulation of monitoring station
The module can forward the event codes received from the control panel to the monitoring
station by means of cellular network. Which reporting path will be used to send the event
code depends on the module configuration.
Fig. 2. Module simulating the monitoring station.
3.3 Work within Internet of Things (IoT)
Fig. 3. Module working within Internet of Things (IoT).
Using cellular network (TCP), the module can communicate with devices in the Internet of
Things (IoT). This allows the module to be integrated e.g. with automation systems and
measurement data acquisition systems. The module can send information about state of
inputs / outputs as well as data from analog inputs and 1-Wire bus to the IoT devices.
In response, the module can receive commands blocking / unblocking the inputs as well as
activating / deactivating the outputs of the module.

5. Installation
Disconnect power before making any electrical connections.

SATEL GPRS-A LTE 9
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 LTE 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).
5.1 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.
5.2 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.
5.3 Installation of antenna
The GPRS-A LTE 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
performance of the antenna.
5.4 Connecting the alarm control panel
Connect the control panel telephone communicator to the TIP and RING terminals.
5.5 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. 7).
3. Connect the devices which are to be controlled by the module to the terminals of outputs.

10 GPRS-A LTE SATEL
Fig. 7. Example of connecting supply and monitoring AC voltage presence.
5.6 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 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 indoors 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).
Fig. 8. Dimensions of DS-T1 temperature sensor enclosure.
5.7 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 500 mA.

SATEL GPRS-A LTE 11
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 mm2, or rigid conductors
with a cross-section of 1-2.5 mm2).
Never connect power supply to APS connector and terminals at the same time.
2. Power up the module. The module will start up.
5.8 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. For more information, please refer to section “Configuring”
(p. 11).
update the module firmware.
5.9 Installing the SIM card
1. If PIN code is required by the SIM card, use the GX Soft program to program the code
(see p. 21).
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 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 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.
6. Configuring
You can configure all the module settings by using a computer with GX Soft program
installed. Communication between the computer and the module can take place locally
(via RS-232 (TTL) port) or remotely (via cellular network).
Module with factory settings can only be programmed locally. Remote programming is only
possible after settings for communication via cellular network (see p. 21). Communication
between the program and the module is encrypted.
Having programmed the SMS control commands in the module (see “SMS control” p. 39),
you can configure some working parameters of the module by using SMS messages.
