MESSAGE
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: Pager number must be unique and can not be the same as any prefix, outgoing
numbers or the beginning of other telephone numbers.
For the SMS messages to be sent, it is required to add the prefix with a country code (48 for
Poland). This prefix is programmed by the service function Prefix for SMS. If the cellular
telephone number is given by the control panel together with prefix, the function Prefix for
SMS should not be programmed.
To enable the transmission of SMS messages, the SMS centre number is to be loaded into
the module’s memory by the service function SMS centre No., depending on GSM network
in which the telephone is activated.
The parameters of the pager system signal should be programmed at the alarm control
panel (or telephone set DT-1) 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

MESSAGES FROM A STATIONARY TELEPHONE SET
The GSM-4S 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.
In order to send an SMS you should:
1. Lift the handset of the telephone.
2. Dial in one sequence the "PAGER station number" and the phone number to which
the SMS is to be sent. The number should be entered rather quickly, without any time
intervals between consecutive digits (the country prefix should be indicated depending on
the programmed Prefix for SMS function).
3. The properly received number is acknowledged in the
handset by two beeps generated by the module. Lack
of acknowledgement or a busy signal means a dialing
error and then the procedure must be started anew
(to facilitate it, you can use the REDIAL option).
4. Enter the text of message following the instructions
below (the time of module waiting for subsequent
characters is not limited):
The module will accept characters in the numeric
mode. Pressing each key of the telephone adds
a corresponding digit to the message.
By pressing the [*] key twice you will enter the text
mode. In the text mode, each numeric key (from 1
to 9) has three letters assigned to it (see Fig. 7).
Pressing a key means selection of the middle letter.
By pressing in turn the key and [*] you will select the
left-hand letter on the given key. The right-hand letter is accessible by pressing the given
key and [#]. In order to reach the space, press the [0] key. To reach the dash, press [0][*],
