Universal monitoring module equipped with telephone designed for use in the 2G, 3G and 4G cellular networks.

The device can work as part of intruder alarm systems as well as automation systems.

It provides reporting from the alarm control panel to the monitoring station and notifies the concerned parties about selected events.

Thanks to its configurable inputs that support analog signals, it can be used to supervise operation of any sensors measuring different physical quantities and report instances when the set thresholds are crossed.

For the module to interact with prepaid SIM cards, it has been provided with functions required to check the account balance and configure notifications of the balance falling below the minimum amount.

GPRS-A LTE universal monitoring module

Full flexibility

The module can be successfully used in many existing and newly built systems. GPRS-A LTE can receive information about events from the connected control panel and forward them to the monitoring stations at security agencies or to the parties concerned via the mobile network. The module connects to the control panel through the control panel dialer (the module simulates the monitoring station) or through appropriately configured control panel outputs connected to the module inputs.

The module can be used to implement remote control functions, such as arming the system or opening the gate, also using the mobile application. The state of module outputs can also be changed automatically in response to specific events.

GPRS-A LTE can give a "new life" to some older alarm systems. It can also work as a stand-alone device, monitoring the state of various devices, automation systems, etc.

GPRS-A LTE Event reporting - scheme

Event reporting

In the area of reporting, information is transmitted via:

  • mobile data transmission - using TCP or UDP protocols
  • SMS messages

Where events are sent using LTE/HSPA+/EDGE/GPRS technology (depending on the capabilities of the mobile network), the module supports two transmission formats:

  • SIA-IP (for communication with any monitoring station)
  • SATEL (for communication with SATEL made devices: STAM-2 monitoring station or SMET-256 reporting converter)

Notification messaging

The GPRS-A LTE module makes it possible to send notifications to up to 8 telephone numbers. This function can be implemented by using:

  • SMS messages
  • PUSH messages
  • CLIP service

The device can send notifications to the recipient through several independent paths. Since the event alert will be transmitted via all of the preprogrammed channels, the information will reach the recipient even when one of them turns out to be unavailable.

Remote control

GPRS-A LTE has 4 outputs, including 2 relay and 2 OC type. They can be remotely controlled and activated in several ways from any location:

  • via SMS messages (from 8 numbers)
  • from GX CONTROL mobile application
  • from a computer with GX Soft program installed
  • using CLIP service (from as many as 10 000 numbers).

Interaction with detection, measuring and other devices

The module inputs can be programmed as NO, NC or analog ones to work in conjunction with devices provided with NO or NC outputs, as well as with a number of analog sensors and digital-to-analog converters, which offers a great many possibilities for the module use.

The module will convert (rescale) the received analog signal to any unit of measure, including temperature or another physical quantity.

GPRS-A LTE Collecting information from many modules

Collecting information from many modules in one place makes it possible to supervise, for example, a wind farm.

Mobile access

The application allows configuration:

  • verification of the state of inputs and outputs (of connected sensors and devices)
  • display of indications from analog inputs and digital sensors
  • viewing troubles with trouble memory clearing option
  • viewing event memory with filtering capability
  • remote control of module outputs (devices connected to them).

PUSH messages give the user permanent access to information.

Importantly, configuration of the application is very simple, and so is connection with the module. All you have to do is send an SMS from the application level to the device and receive the configuration data in response. Another, equally convenient way is to scan the QR code that is generated in the GX Soft program or in a preconfigured application.

Functional software

GX Soft is an advanced tool with a friendly and clear interface, intended for configuration as well as diagnostics of SATEL communication modules. The module and the program can interact locally (via RS-232 (TTL)) or remotely (via mobile network).

GPRS-A LTE Easy and secure connection - scheme

Easy and secure connection

Thanks to the SATEL connection set-up service, you can enjoy many functionalities of GX CONTROL and GX Soft. Configuration of communication between the application / program and the GPRS-A LTE module takes just a few moments, without any need to use external IP address or advanced network settings. When being sent, the data are encrypted using a sophisticated algorithm to ensure security of the transmission.

Remote software update

GPRS-A LTE is compatible with the UpServ program, which enables the device to be remotely updated. This allows the installer to quickly add new functionalities without having to physically visit the premises and dismount the module.

GPRS-A LTE universal monitoring module


GPRS-A LTE is a universal monitoring module that can work autonomously or as part of an intrusion and hold-up alarm system, as well as automation systems. It is equipped with telephone designed for use in the 2G, 3G and 4G cellular networks.

In the alarm systems, this module can be used together with any alarm control panel to implement reporting. For this purpose, it should be connected to the dialer or suitably configured outputs of the control panel.

The device has 8 inputs, which can be set as digital (NO, NC) or analog. Those that work as analog ones can be used in automation systems or to monitor a wide spectrum of external devices, such as temperature, pressure and humidity sensors. GPRS-A LTE also has a 1-Wire bus, to which you can connect up to 8 DS-T1 or DS-T2 digital temperature sensors.

The module can send the measurement data using the MQTT, JSON, JSON/HTTP and MODBUS RTU open communication protocols. An option is provided to create a server collecting data from many modules. This information can be processed and visualized, e.g. to supervise the environmental parameters prevailing in a group of cold stores, warehouses or production halls. This is part of the concept of so-called Internet of Things (IoT). If the set threshold values of signals on the analog inputs or from 1-Wire sensors are exceeded, GPRS-A LTE can report such an event in response to the monitoring station or send notification to selected users. You can also program an automatic change of the state of selected outputs in response to specific events, such as switching on the heating on a significant drop in temperature.

The module offers notification to a maximum of 8 users, in several ways: using SMS or PUSH messages, or via the CLIP service.

The device has 4 programmable outputs that can be controlled remotely using SMS, CLIP, GX CONTROL mobile application or GX Soft configuration program, as well as IoT. GPRS-A LTE can be used for remote control of the alarm system or other devices.

For programming and configuration, you should use a computer with the GX Soft program installed. The computer can connect to the module locally (RS-232 (TTL) port) or remotely (data transmission over the cellular network*).

Remote update of the device firmware is possible owing to GPRS-A compatibility with the UpServ update server.
