2. LIMITATIONS 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).
3. DESCRIPTION OF THE MODULE
MODULE TERMINALS:
+12V –power supply input (12 V DC ±15%)
GND –ground (0 V)
FLT –alarm output, GSM telephone failure or insufficient range (OC; 50 mA)
R-1, T-1 –extension telephone line (connection to the alarm control panel or to
a telephone set)
IN1–IN4 – inputs
The FLT output is a generalized fault indicator. It gets active if connection with the base
station is not confirmed by the module within 10 minutes. It may be caused by a telephone
trouble (phone damaged or no SIM card), antenna failure (antenna cable damage), or loss of
range due to other reasons. The fault alarm stops maximum 30 seconds after the alarm
causes ceased to exist.
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).

4. OPERATING THE GSM TELEPHONE
As any other cellular telephone, the industrial cellular telephone requires a SIM activation
card to operate. The user of the GSM LT-2 module has to obtain such a card on his own.
The SIM card should be inserted into a special recess provided on the right-hand side of the
printed circuit board. The PIN code, if necessary, is to be entered into the module memory by
means of a telephone connected to terminals R-1 and T-1 (programming function 16), or by
means of a computer and the DLOAD10 program.
Note: The change of PIN code stored in the SIM card, or entering the PUK code is possible
after putting the SIM card into an ordinary cellular telephone.
5. INSTALLATION
It should be borne in mind during installation that the GSM LT-2 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.
Never turn on power supply of the module and GSM telephone without external
antenna connected.
The installation must be carried out in a strict compliance with the following activation
procedure:
1. Make a complete wiring.
2. Turn on the module power supply without SIM card inserted.
3. Using a DTMF telephone set or the DLOAD10 computer program, specify the module
working parameters (including the PIN code).
4. Turn off power supply.
5. Insert SIM card into the socket (see: Fig. 3).
6. Turn on power supply.
A non-configured GSM LT-2 module will wait 10 minutes after power-up for entering the PIN
code of the SIM card. If this does not happen, the device will automatically deenergize the
telephone line and generate the trouble signal (i.e. it will short the FLT output to common
ground), thus making further programming from the telephone impossible (programming from
the computer by means of the DLOAD10 program will still be possible). If this is the case,
turn the module power off and on, so that the module can re-enter the programming mode.
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.
If the supply voltage is lower than 9.8 V, restart of the module will follow. Therefore, be
careful that the module supply voltage never drops during operation below 9.8 V at the
maximum current consumption.
6. OPERATION OF THE MODULE WITH ALARM CONTROL PANEL AND STATIONARY
TELEPHONE
As shown in Figure 1, the module is to be directly connected to the control panel’s public
telephone line terminals.
It maintains impedance and voltage across the R-1 and T-1 terminals as necessary for
correct operation of the telephone set. The terminals can be automatically deenergized in
case of a loss of communication with the base station (which is accompanied by operation of
the FLT trouble indicator – see: programming function No. 17).
When the control panel goes "off-hook", or when a user lifts the handset of a telephone
connected to the terminals T-1 and R-1, the module will generate the continuous dialing tone
and receive the tone or pulse dialing signals (similarly as the telephone exchange).
The telephone number can include digits and special characters: #,*,+. The phone number
should be dialed just like from a cellular phone, as required by the operator of the network
into which the telephone is logged. It is recommended that the number begin with the "+"
character and country code prefix (48 for Poland). Sometimes you can dial just the mobile
phone number, or the area code and stationary telephone number.
Examples:
[*][0][4][8][5][0][1][1][2][3][4][5][6] – connection to mobile phone (with prefix "+48")
[5][0][1][1][2][3][4][5][6] – connection to mobile phone (number without prefix)
[5][8] [1][2][3][4][5][6][7] – connection to stationary telephone, (in this example, 58
is location area code)
If the first four digits of the dialed number correspond to the pre-programmed "pager station
number", the module goes to the procedure of receiving the alphanumeric message and
sending it as an SMS text message (see section Sending SMS messages). Checking of
the first four digits is always performed.
When connection is established by the cellular telephone, the module will transmit LF audio
signals between the extension line T-1, R-1 terminals and the cellular telephone. After the
handset is lifted by the subscriber the connection is established with, the module changes

the direct voltage polarization across the extension line terminals T-1 and R-1. This function
makes it possible to keep individual tariffication of phone calls.
An option is provided for calling the phone number of the module SIM card. The incoming
calls are directed to the extension line terminals R-1 and T-1, which generates the ringing
tone, in much the same way as with operation of the cable telephone line. It is then possible
to answer the incoming calls by means of a stationary telephone set connected to that
telephone line.
The GSM LT-2 module makes it also possible to present the calling party number (CLIP) by
means of FSK or DTMF.
7. GSM LT-2 WITH MONITORING STATION
Figure 4.
The GSM LT-2 module permits site monitoring by means of SMS short text messages.
The SATEL's STAM-1 monitoring station only supports (from version 4.07) SMS monitoring
related to the input status of the GSM module located on the site (e.g. GSM-4S or
GSM LT-2). Changing the status of the device inputs will result in sending the event as an
SMS message with preprogrammed contents to the GSM module number on the monitoring
station side. The SMS message contents and the corresponding codes are to be defined in
the STAM program when editing the client.
The STAM-2 monitoring station (from version 1.2.0), besides monitoring the status of module
inputs, enables also full monitoring of events from the interfacing alarm control panel.
The panel is sending all events as SMS messages, the format of which (CID or 4/2) is to be
programmed by means of the DLOAD10 program (see: MONITORING). The contents of
SMS-messages and the corresponding codes are to be defined in the STAM-1/STAM-2
program when editing the client.

8 User manual GSM LT-2
The example of module connection to station is shown in Fig. 4.Connect the GSM LT-2
module to the computer serial port (COM1 or COM2) with a cable made according to
Figure 6. Such a cable, designated with the DB9F/RJ-KPL symbol, is available in the
SATEL's offer.
8. INPUTS
The GSM LT-2 module is fitted with four inputs whose technical design is similar to that of the
control panel zones. Support of the inputs consists in monitoring any changes of their status.
Supervision of individual inputs can be bypassed by the module user. The inputs are
supported by the module irrespective of the telephone line support (R-1, T-1).
8.1 DESCRIPTION OF THE INPUTS
The detectors of both types, NC and NO, can be connected to the inputs of the module.
The type of detectors is to be entered in the service function 43.
The first parameter, the sensitivity of the input is programmed for each input (functions
45-48). The sensitivity of the input is defined as a minimum time which must elapse from
the moment of the status change at the input (open for NC input, closed for NO input),
in order to classify such change as violation of the input. This time delay can have the values
within the range from 20 ms to 1275 ms.
The time to restore the input is the next parameter to be programmed for each input
(function 44). Time to restore the input is defined as a time period that must elapse from the
end of input violation to the moment when the input can register a next violation (4 seconds
or 4 minutes).
Controlling the operation of inputs consists in bypassing and unbypassing their operation.
This control can be performed manually or remotely. The manual bypassing option can be
disabled (in service mode, using function 95). The remote control is effected by means of
a telephone which supports DTMF signaling (functions 82–91) as well as through SMS
messages (functions 71–80).
The input can be automatically bypassed after 1–15 violations, for a specified time, or
permanently (functions 49–60). The input is bypassed after the end of violation. Input can
also be bypassed after violating another input (designated as the bypassing input
- function 70). The bypassed status of the inputs as a result of violating the Bypassing input
will last as long as the given input is violated.
8.1.1 Bypassing by DTMF signals from R-1, T-1 terminals
To have the remote control by dual tone phone push-button (connected to R-1, T-1 terminals)
it is necessary to properly program the module by using the service functions, as follows:
•Enter the device service mode.
•Using function 95, determine the inputs to be bypassed manually.
•Program the (6-digit) control code to enable the inputs to by bypassed/unbypassed
locally – function 96.
•Exit the service mode by hanging up.
In order to bypass/unbypass an input do the following:
•Pick up the telephone receiver and enter the control code (if valid – the device will
generate four short and one long beeps).
•Bypass/unbypass input (according to the scheme described in function 96). Acceptance of
the command will be acknowledged by three short beeps.
Replace the receiver to make the device return to its normal operating mode.
