Description

UNIVERSAL MONITORING MODULE

GPRS-A is a universal monitoring module, provided with GSM telephone, supporting data transmission using 2G technology.

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.

Full flexibility

The module can be successfully used in many existing and newly built systems. GPRS-A 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 GSM 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 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.

Event reporting

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 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 1024 numbers).

Monitoring premises

GPRS-A can find use in yachts, caravans, cottages, etc. When used in conjunction with a number of detectors, it will reliably protect the interior of the given premises. The module can, for example, send a notification to inform the owner or selected parties that the door is open or an attempt was made to start the engine.

As it can work e.g. with temperature and humidity sensors, the module will be a perfect choice for monitoring environmental conditions during storage of food, medicines, etc. by:

• sending information about selected parameters in real time
• triggering alarm when preset limits are exceeded or input state changes
• responding to specific events

IoT – Internet of Things

The GPRS-A universal monitoring module can be used in conjunction with automation and data acquisition systems. As it can exchange information with other devices by using the MQTT, JSON and MODBUS RTU open communication protocols, its operation fits in fine with the concept of the Internet of Things.

It gives the users a wide range of possibilities of using, processing, storing and visualizing data. Information sent by the module can be processed by using both commercially available software, as well as applications created from scratch.

When used as part of IoT, many modules are capable of sending data (via GPRS) to a previously set up server. Such a server can also be used as a proxy to implement remote control of the outputs of all connected modules. The system built in this way is scalable. Communication with the server can be configured from the GX Soft program.

Digital data collection

The device is provided with a digital 1-Wire sensor bus. This allows up to 8 detectors to be connected, the maximum bus length being up to 30 m. When used with the SATEL DS-T1 or DS-T2 sensors, the GPRS-A module will perform very well wherever temperature monitoring plays a crucial role.

Two (upper and lower) threshold values can be assigned to the analog inputs and 1-Wire sensors. Crossing these thresholds may result in:

• sending report to the monitoring stations
• sending notification to the selected parties
• automatic response of the module, i.e. performing a preprogrammed action

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.

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).

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 GPRS).

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 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.
