UNIVERSAL GPRS MONITORING MODULE

GPRS–A is a universal monitoring module that can work as

a stand–alone device or as part of intruder alarm systems as well as

automation systems. The device is provided with a GSM telephone

that supports data transmission in 2G technology.

In the alarm systems, this module can be used to implement

reporting, in conjunction with any alarm control panel. It connects to

the control panel with the control panel dialer or appropriately

configured outputs.

The device has 8 inputs, which can be set as digital (NO, NC) or

analog. Those that work as analogue ones can be used in automation

systems or to monitor a wide range of external devices, such as

temperature, pressure and humidity sensors. Additionally, GPRS–A

has a 1–Wire bus, to which up to 8 DS–T1 digital temperature

sensors can be connected. The module can send measurement data

using the MQTT, JSON and MODBUS RTU open communication

protocols, via GPRS. It is possible to create a server that will collect

data from many modules. Gathered informations can be used for

processing and visualization – e.g. to supervise environmental

parameters prevailing in a group of cold stores, warehouses or

production halls. This fits in with the concept of the so–called Internet

of Things (IoT). In response to exceeding the preset threshold values

of signals on analog inputs or from 1–Wire sensors, GPRS–A may

respond by reporting such events to the monitoring station or send a notification to the indicated users. It allows to program an automatic reaction consisting in

changing the status of selected outputs, e.g. by switching on the heating system due to a significant temperature drop.

The module offers notifications of up to 8 users, in several ways: by using SMS or PUSH messages, or via the CLIP service.

The device has 4 programmable outputs that can be remotely controlled using SMS, CLIP, GX CONTROL mobile application or GX Soft configuration

program, as well as via IoT. GPRS–A can thus be used to remotely control the alarm system or other devices connected to the module.

Programming and configuration is performed using computer with the GX Soft program. Connection with the module can be local, via RS–232 (TTL) port, or

remote, by connecting to the device via GPRS.

Remote update of the device (its firmware) is possible thanks to the interaction with the UpServ program.
