corresponding codes are to be defined in the STAM-1/STAM-2 program when editing the

8. SENDING SMS MESSAGES
If the control panel has the function of messaging to the pager system, it can be used for
sending SMS messages.
To enable sending the SMS messages, program in the GSM-LT module the telephone
number of Short Message Service Center (function 02 and 10) and telephone number of
pager station (function 06), and in the alarm control panel the telephone number of pager
station, as required, and enter into the control panel memory the appropriate text to be sent.
The telephone number to be programmed in the control panel must consist of:
1. The "pager station number" pre-programmed in the GSM LT-1S module.
2. The cellular phone number to which the SMS message is to be sent (with the country code
prefix, but without the „+” character).
Note: Parts of the number may not be separated from each other by any time interval
(pause); the digits must be sent by the control panel as one sequence in DTMF or
pulse mode. In case the module has any trouble with receiving the „pager” station
number in the tone mode, it is necessary to set the pulse dialing mode in the control
panel.
8.1 PROCEDURE FOR CONVERTING PAGER MESSAGES INTO SMS MESSAGES
When the alarm control panel is "off hook" and after dialing the number – the module checks
the first four digits of that number. If these digits agree with the programmed "Pager tel. No."
in the module, the module receives next digits up to the pause (telephone number to which
SMS message will be sent); then the module sends hand shake signal (similar as pager
station) and receives the message sent by the control panel. Next, this message is
transmitted via the SIM300CZ cellular telephone as SMS text message.
Note: The programmed “Pager station number” must be unique and must not coincide with
the beginning of other telephone numbers.
The SMS sending systems may require adding a prefix with the country code (48 for
Poland). The prefix (without „+”) is to be programmed together with the cellular phone
number.
To enable the transmission of SMS messages, the “SMS center No.”, must be loaded into
the module, depending on the GSM network where the telephone is activated. It must be
preceded by the „+” character and the country code suitable for the operated network.
Parameters of the pager system signal should be programmed at the alarm control panel
(or the DT-1 telephone set) as follows:
control panel 1 C 2 2 0 A 0 E 7 0 8 A
DT-1 C 1 2 2 A 0 E 0 0 7 A 8
8.2 SENDING SMS 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
system.
