Device description an operation
The GSM device is an analog telephone line simulator, which can be used as an accessory to an alarm center
to replace an already existing telephone line of poor quality or in a location that is otherwise difficult to install.
The advantage of the module is the so-called Plug&Play design, thanks to which only an active SIM card is
required to use the line simulator function.
A full PSTN line simulation can be achieved by generating line and ringing voltages and transmitting DTMF
tones. This standard telephone line guarantees that you can connect the module to the existing system without
any particular transition difficulties.
The GSM module is capable of two-way communication. In case of an incoming call, the device connected to
the TIP/RING points can be remotely accessed and programmed (if the device is suitable for this and the
available network conditions allow this).
Using the module SMS command, knowing the security code, the module settings can be modified at any time
without having to establish physical access.
The module has 1 SMS input. This input can be closed to the GND point in the Normal position, i.e. Normal
Close (NC). An SMS notification can be triggered by interrupting the closed loop formed between the input
and the GND point. You can change the text of this SMS and the phone number to be notified at any time
using 1 SMS.
The module has 1 open collector output, which is connected to GND when activated. If a relay is connected
to it, one half of the relay must be connected to +12V and the other half to the Open collector for proper
operation. For inductive loads (e.g. when using the aforementioned relay), the use of a protective diode is
mandatory!
The output can be controlled with a free call from an unlimited number. When controlling by calling number
identification, the numbers are stored in the internal memory of the module (in this case, 1000 numbers can
be entered). Call number identification prevents unauthorized control of the device connected to the output.
The output can be loaded with 300mA and a maximum voltage of 30V can be connected to it.
In addition to continuously monitoring the power supply, the module also checks the status of the GSM field
strength. It can be read on a graph that can be displayed with a resolution of up to 1 hour using the
programming software.
The module can be programmed using an SMS command or programming software on a PC.
In a later development, with a simple FW update, it will be possible to convert Contact ID codes from the
alarm center into text and send SMS to 8 specified phone numbers in addition to the line simulator functions.
