The GPRS-T4 module is a device dedicated for use in intruder alarm systems for
the purpose of reporting and messaging via the GSM networks. The main task of the
module is monitoring the status of inputs. A change of the input status results in sending
event codes to the monitoring stations or notifying selected telephone numbers by means of
SMS message or CLIP service. This makes it possible to supervise operation of various
devices, including alarm control panels without telephone communicator. The module inputs
can be programmed as digital or analog ones. Owing to its analog inputs, the module can
execute functions which are used in automation systems.
Event codes are sent in the form of GPRS transmission or SMS messages. Using the GPRS
technology makes it possible to send the codes to the STAM-2 monitoring station or
SMET-256 converter. The codes in SMS format can be sent to any monitoring station
which supports the SMS reporting feature.
In order to execute some functions, the module makes use of the features offered by
the CLIP service, which enables identification of the calling party and presentation of its
telephone number. Thus it is possible to control the outputs, trigger and send test
transmissions, as well as report events without incurring any costs.
