User Manual GSM LT-1S 1. GSM LT-1S MODULE FEATURES • Simulation of analog telephone line by the use of cellular connection. • Interaction with alarm control panels and other equipment (e. g. DT-1 telephone dialer) which use the analog telephone line for transmitting voice information about alarms, or for sending text messages to paging system).

L IMITATIONS OF USE As the mobile phones are designed for the maximum efficiency of speech conveyance, the data compression feature which is used in them brings about distortions in the transmitted audio signals, which may make difficult or even impossible sending modem signals through a simulated telephone line (downloading, monitoring).

+12V GND FLT R-1 T-1 RS-232 Figure 2. View of the GSM LT-1S module board. In its active state, the FLT output is shorted to the ground. The FLT output may be connected to the alarm control panel input, or it can directly control the relay operation (its maximum current-carrying capacity is 50 mA).
5. I NSTALLATION It should be borne in mind during installation that the GSM LT-1S module must not be located in the vicinity of electrical installations, since this may involve a risk of malfunctioning. Pay special attention to how the cable is laid between the module and the telephone terminals of the alarm control panel.
Figure 3. Entering the SIM card into its socket. The module power supply should have a sufficient current capacity. The recommended power supply unit (e.g. APS-15; APS-30 manufactured by SATEL) should be equipped with its own battery. It is suggested that the power supply be located within 3 m from the module.

ENDING MESSAGES FROM A STATIONARY TELEPHONE SET The GSM LT-1S module user has an option to send SMS messages form a stationary telephone set which generates DTMF signals and is connected to the terminals R-1 and T-1. This operation is done in much the same way as sending SMS messages in the PAGER...
The GSM LT-1S can store in its memory 62 alphanumeric characters to be sent as an SMS message. At an attempt to enter a longer message, the excessive portion of the text will be omitted.
SMS if there is no acknowledgement of receiving the CLIP information (functions 36–39). The transmission acknowledgement consists in the telephone user rejecting or receiving the connection set up by the GSM LT-1S module. The acknowledgement can only take place within 10 to 20 seconds of the connection set-up.
10.1 DLOAD10 PROGRAM The GSM LT-1S module is delivered together with the DLOAD10 program which enables the module to be programmed from a computer. The program is designed for IBM PC/AT compatible computers. It works in any computer hardware configuration in the WINDOWS (9x/ME/2000/XP) environment. It is recommended that the program be installed on the computer hard disk.

User Manual GSM LT-1S Having installed the program, start it. Access to the program is protected with an access code. After installation of the program, the access code is: 1234 and can be changed in any string of 16 alphanumeric characters. As long as the code has its factory setting, pressing the „ENTER”...

DTMF signals, as well as enables the module status and antenna signal level to be checked. In order to change the settings or check the status you should first enter the GSM LT-1S module programming mode. This operation requires entering a six-digit access code.

GSM LT-1S SATEL Entering a correct command is signaled in the handset by three short beeps (SSS), while commands which are incomprehensible or have an incorrect number of characters are signaled by two long beeps (LL). The function completed, the module returns to the programming mode. If you hang up, the module will quit the programming mode and return to the normal operating mode.

User Manual GSM LT-1S If the function is called by entering [1][9][ * ][ * ][?][?][#], the second "?” character will determine whether the test function is to be random or not: 0 – no, 1 – yes By default, the random transmission is disabled.

GSM LT-1S SATEL programmed with the appropriate function. Using the DTMF signals, you can program passwords composed from digits only (0...9), whereas the DLOAD10 program makes it possible to program passwords composed from letters and digits. The [2][8][ * ][ * ][#] sequence will erase the previously programmed password.
Current-carrying capacity, FLT output................50 mA Weight..........................216 g ATTENTION: The SATEL Company recommends that performance of the GSM LT-1S communication module be regularly tested. An efficient GSM module, which interacts with the security system, greatly increases the chance of successful transmission of alarm information.
