Universal Communication/Monitoring Module Satel GPRS-A

GPRS-A is a universal monitoring module, provided with GSM telephone, supporting data transmission using 2G technology. The device can work autonomously or as a part of intruder alarm and automation systems. It replaces the GPRS-T1/T2/T4/T6 modules. The module connects to the control panel through the control panel dialer or through appropriately configured control panel outputs connected to the module inputs. It provides reporting from the alarm control panel to the monitoring station and notifies the concerned parties about selected events. The device has 8 inputs that can be set as digital (NO, NC) or analog. Thanks to the configurable inputs that support analog signals, it can be used to supervise operation of any sensors measuring various physical quantities (e.g. temperature, pressure, humidity) and report instances when the set thresholds are crossed. The GPRS-A module also has an 1-Wire bus that can support up to 8 digital DS-T1 temperature sensors.

The module can send measurement data via GPRS using the MQTT, JSON and MODBUS RTU open communication protocols. It is possible to create a server that will collect data from many modules. The gathered information can be used for further processing and visualization – e.g. to supervise environmental parameters prevailing in a group of cold stores, warehouses or production halls. This coincides with the concept of 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 selected users. It is possible to setup 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 are performed using computer with the GX Soft program. Connection with the module can be local, via RS-232 (TTL) port, or remote, via GPRS.

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