1 Short functional description of device
In Standalone mode the unit behaves like a monitoring station receiver which receives and handles
the CONTACT ID communication of alarm control devices. It compares the report codes with the filled
in event codes of the program table and at the occurrence of the desired event it sends the assigned
SMS message and initiates a call (siren sound is played). By this means the users of the alarm control
panel can be notified of any signals, differed by the event and subject of event (user, zone, partition).
Notifications are not limited to differ only few kind of events as it is usual with all other GSM (SMS)
communicators, with trigger inputs only. The best describing definition for this feature would be:
Converting Contact ID messages to programmable SMS messages and phone call notifications
Further function is that by controlling the contact inputs the communicator sends the assigned SMS
messages and calls the pre-set telephone numbers.
In transparent mode fully replaces phone line. By this means the alarm control panel can send the
report codes to monitoring station, or a simple phone device can be used on places where the phone
line is not available (elevators, SOS or INFO call points, weekend houses,…)
By controlling the contact inputs the communicator immediately sends the CONTACT ID messages
assigned to the inputs to the given monitoring station number and this way shorting down the
signaling time of the alarm state to monitoring station, providing more precious time to react, while
complete communication to monitoring station with full information of events in progress can take its
time.

3 Connection
In order to operate properly, the device must be equipped with a valid SIM card and the external
antenna must be connected to the antenna connector. Use the supplied antenna or any other GSM
antenna that suites the needs for installation. The SIM card should be inserted to the card holder
“door” (the moving part of card holder), as shown on picture. The Door must be pushed toward the
PCB until completely “closed”, i.e. the two parts of card holder are overlapping, and after that the card
holder should be LOCKED, by puling the holder ”door” toward the terminals (as marked on the holder).
The locking of card holder gives a click sound. If the card was not placed properly as it should be, the
card holder door can not be locked and turning the PCB in horizontal position with card holder toward
the ground will cause the holder to open. In this case, the device will not operate properly, and may
cause the damaging of SIM card. Please be sure that the SIM card is placed properly before powering
up the device.
Warning: The SIM card should never be removed or added while the device is powered up.
3.1 Power supply
SC-GSM communicators can be powered from USB connection for programming only (downloading of
settings). For normal operation required the external power (connected to terminals +12V and COM).
The device will be functional with any power voltage between 9 and 30 V DC is applied to the
terminals.
3.2 Emulated phone line
The TIP and RING terminals of the SC-GSM device provides an emulated phone line. Connect these
terminals where the PSTN (regular phone line) is supposed to be connected to the device that will use
this communicator. In case of connecting to alarm panel, use the INCOMMING LINE terminals, (usually
marked with TIP/RING or T/R, or Ti/Ri...).
3.3 Trigger inputs
There are 2 CONTACT inputs on device, marked as Z1 and Z2. These inputs are used to trigger a voice
call to a user, send a SMS message, or to send a specified Contact ID code to a monitoring station
(when device is set to transparent mode). These inputs are triggered when connected to the COM, i.e.
to the supply negative line. When connecting the device to an alarm panel, if the power is supplied
from alarm panel (connected to its AUX terminals) these inputs can be directly connected to PGM
outputs of alarm panel, that are “open collector” type, since when activated, these outputs provide a
shortcut to the panel ground. With such connection, no other wiring is required. If the PGM is REELAY
type (two connection points), than one pole of the output relay must be connected to the same place
with the communicator COM terminal, and the other to Z1 or Z2, in balance with programming.

4 Configuration of device
Connect the device with USB cable to a windows PC (Compatibility: Windows 7, 8.1, and 10), and a
new drive will be installed. When connected to that machine for first time, the driver will be installed
first, then the new drive will be found. This drive is the flash memory of SC-GSM device, and contains
the software and this manual. You can run the software from device, or copy it to your PC and run it
from there. When the device is powered through terminals, the USB cable can be plugged or
unplugged at any time, it will not affect the device. The windows machine might require a proper
closing of USB connection before unplugging the cable.
4.1 Setup program connection
If the device is password protected or a wrong type of device is connected on USB port, the
PASSWORD field is displayed. If a wrong password is entered, the software will display the status fields
only Settings are not displayed and can not be changed. This mechanism prevents unauthorized access
to device settings.
As the software successfully connects to the device, it reads out the device and shows the status,
device version and actual settings in device (marked red on following picture):
In case that software does not show a “connected” status or the firmware version, the USB connection
was not made properly. Please select a different USB port check the USB cable. If the problem persist,
the device USB driver might be in conflict with some other driver in windows, restart the windows or
try the connection on another machine.

4.2 Moving data between the PC and the device
Reading out data from the device happens automatically as soon as connection is established. Settings
can be saved to PC or loaded from PC file. These icons are used to handle the settings data:
(File_reading / File_saving / Download to device )
IMPORTANT NOTICE: if a new settings file is loaded or ANY setting is modified on software screen, all
data needs to be downloaded onto the device. You can make all required changes in software, and then
download data. Changes that were not downloaded will be terminated when the software is closed or
the connection is cut (cable unplugged).
4.3 Device code lock (protection)
The device can be locked with a security code. By default, there is no code but once entered, the code
will be required for each connection. After connecting, the new code can be entered with the icon:
After connecting via USB, if the device was set with a code, the software requests to enter
the device code. If you cancel the code entry, the software will display only the status and no settings
can be red or edited. After closing re-starting the software, the code entry box is displayed again. Only
after the right code was entered, the software will be fully functional, presenting the whole window
with all settings displayed and editable.
WARNING: If the password is lost or forgotten, only way to access to device setting is with FACTORY
DEFAULT. For that procedure, the device must be sent to appropriate service
4.4 Device Status
The left side of the software window is showing the device status. This part is ALWAYS VISIBLE, even
when the device is protected with code lock. These are the fields in the status view:
Field name Options (description)

4.5 General setting
The General setting parameters are valid for both operating modes, and in this area the operating
mode (transparent or standalone) is selected
4.6 Transparent mode
In this mode, device can be used as a transparent GSM Gateway, to forward voice signals (DTMF or
speech) from a phone device or alarm panel through a GSM network, to called party or a monitoring
station receiver. The phone device (alarm panel) connected to the RING/TIP terminals make the
dialing, the SC-GSM device just dials that number, and opens the VOICE channel to transfer all sounds
in high quality through GSM network. In case of incoming call, the device will ringing, the connected
phone device or alarm panel.
Operating mode TRANSPARENT operating mode (chapter 3.6)
STANDALONE operating mode (chapter 3.7 )
PIN code PIN code of the SIM card must be entered here if the card is set to request a
PIN. If a wrong PIN is entered, the device will „lock” the PIN card by trying to
activate the SIM with entered code, over and over. After 3 unsuccessfull PIN
code entries, the SIM requires a PUK code. This code must be entered with a
different device (mobile phone)
Incomming SMS notice Incomming SMS messages will be forwarded to the given telephone number
Z1 input setting the sensitivity and type of contact input Z1
Z2 input setting the sensitivity and type of contact input Z2
(Next fields available in Standalone mode ONLY)
Phone numbers User phone numbers where the unit can send the signal in the form of SMS
and/or call (to maximum 4 numbers).
ACK If the ACK field is selected next to a number, the device requests an
acknowledge signal for every call made to this number. Acknowledge signal is
any DTMF signal (any number from telephone keypad). If the acknowledge is
not received, the call is repeated until the acknowledge is made, but maximum
3 times. If the Acknowledge is received, all further calls for that event are
terminated. This means that the called party, who acknowledges the call, will
STOP the calls to numbers that are next in order (T1/T4).

SC-GSM Alarm Signaling Communicator v1.3 9 EN
Z1 and Z2 contact inputs are used as inputs of independent alarm communicator, triggering them
causes the sending of programmed event code (Contact ID protocol) to the programmed Receiver
Phone Number, paired with the programmed Account Id.
The partition number in the message is 01 and the value of the zone in the message is 001 and 002 and
they cannot be changed. Communication format is CONTACT ID. You can find the requested Contact ID
code in the Chapter 6, or the “Contact-ID-codes-with-explanation.PDF” file.
The best example of usage of these inputs is when the SC-GSM is used with alarm panel, to send a
QUICK signal of an alarm state, while the dialer in alarm panel slowly makes the complete reporting of
complete events through the emulated phone line. To achieve this, it is enough to connect a PGM or
BELL output from alarm panel to a zone input, along with ring/tip lines and the AUX (power supply)
wires.
4.7 Standalone mode
This mode is used to send notifications and informations from alarm panel directly to USERS. When
the alarm panel transmits a selected Contact ID event Code (through emulated phone line on ring/tip
terminals), SC-GSM device simulates a monitoring receiver, accepts the code and confirms the event
reception to alarm panel. After that, the received Code is compared to all codes set in the „Alarm
Event Handling”, and if it exists in the tabble, the communicator makes the programmed procedure-
starts a voice call or sends SMS messages to selected user numbers (1-4). The two inputs do the set
procedure same way, but activated with an external triger (contact).
In this mode the device expects to receive signal in the format defined by the CONTACT ID standard.
The Contact ID Message is defined this way:
SUBSCRIBER ID
XXXX
EVENT QUALIFIER
Event or Restore
EVENT CODE
XXX
PARTITION
XX
ZONE or USER
XXX
8556 1 401 01 001

SC-GSM Alarm Signaling Communicator v1.3 10 EN
In the example , the received Contact ID code /8556 18 1 401 01 001/ means that a system with ID
number (“account number”) 8556, has sent a signal that EVENT (1) of ARMING (401) was made in
Partition 01, by user 001. With settings as shown on picture on top of this page, Appropriate SMS
message for this code ,”ANGIE left home” (Angie is user 001), will be sent to sent to T1 telephone
number.
Another example: When the alarm occurs in zone 2 of the alarm system, the code 8556 18 1 130
01 002 will be transmitted, and the SC-GSM device will be sending the “Burglary in the Hall!” SMS
message to required two phone numbers and starting call the phone numbers T1 (01234567891) and
expect the ACKNOWLEDGE from the called party (any button on dialer pressed) will be expected. If the
T1 number is not acknowledged, the communicator calling the next phone number T2 ( 01234567892).
4.7.1 Setting the signaling in standalone mode
Each line of the table should be set like this:
Code
E/R
Part
Zone /
User
C1,C2,C3,C4
S
MS message
S1,S2,S3,S4
CID code
(3 digit)
E: event

If the received Contact ID Code fits the setting in one line of the table, the SC-GSM will perform the
procedure of calls and messages as set in that line. Each line is independent from another. You can use
the same Code in several lines, if any of other “filters” that are used for the received code comparation
(E/R, Part, Zone/User) differ from each other.
4.7.2 The Contact ID codes comparation
Code: Contact ID code that should be received in the Contact ID message from alarm panel, in
order to make the procedure that is defined in same line of the table. You can find the
requested Contact-ID code in the Chapter 6, or the “Contact-ID-codes-with-
explanation.PDF” file.
E/R: Event or restore of the event defined by the code, along with the CODE it presents the
event that is being transmitted. For example 1-130 is Event for Burglary alarm, and the 3-
130 is RESTORE of Alarm state (zone closed or system disarmed). Also 1-401 means
ARMING, while 3-401 means DISARMING.

SC-GSM Alarm Signaling Communicator v1.3 11 EN
Part: The Partition number that should be received in the Contact ID message from alarm panel
in order to perform the procedure defined in that line of the table. If this field was left
empty, the “partition filter is off”, so the device will not check the Partition number in the
received Contact ID message, and the procedure will be performed for ANY partition
signal, if the rest of receive message fits the settings.
Zone/User: The Zone or User number that should be received in the Contact ID message from alarm
panel in order to perform the procedure that is defined in that line of the table. If this
field was left empty, the “zone filter is off”, so the device will not check the Partition
number in the received Contact ID message, and the procedure will be performed for ANY
partition signal, if the rest of receive message fits the settings.
4.7.3 The reporting procedure
C1-C4: The marked field means that that phone number will be called if the received message
fits the setting for the code comparation. The C1 means „Calling phone number T1”, C2 means „Calling
number T2”, etc. If the field is left empty, that number will not be called even if the received message
fits the setting for the code comparation. The „ACK” field next to number affects the call order. Please
refer to field explanation on chapter 4.5 „General setting” (page 7), or the „important Notices” below.
SMS Message: The text that will be sent to the selected numbers when the received Contact ID
message fits the setting for the code comparation.
S1-S4: The marked field means that that the set text will be sent in the SMS message to that
phone number if the received message fits the setting for the code comparation. The S1 means „Send
message to phone number 1”, S2 means „Send message to number 2”, etc. If the field is left empty,
message will not be sent to that number even if the received message fits the setting for the code
comparation.
Important Notices:
 The procedure will be performed in following order: first the SMS messages are sent to all required
numbers, after that the required calls are made, in numeric order (from T1 to T4). If the
acknowledge from some number is required, that call will be repeated until acknowledged or
timed out. The next call will be made only after time out.
 Acknowledge confirms call to THAT number and stops all other calls for that event that are
following in order (1-4).
 Maximum duration of call is 20 seconds including the ring time. If the acknowledge is received, the
call is immediately finished.
 If „ACK” reception acknowledgement is set and the acknowledge signal is not received during the
call time, the device will end the call and repeat the call, maximum three times. After that the call
is timed out and next call is made.
 When a number is called, a SIREN SOUND is played, until the end of call.
 If Part (partition) or Zone/User (zone/user) is left blank, that value in the Contact ID message will
be disregarded, the SC-GSM will make the calls and sent the messages that are set in this line, no
matter what value was sent by alarm panel (if the other fields fit the received message)

SC-GSM Alarm Signaling Communicator v1.3 12 EN
5 LED signals
The LED signals show the communicator’s operating state. Following the LEDs on device, you can see
the momentary situation i.e. the status. In Transparent mode:
NORMAL OPERATION
In “Idle state”, when everything is „Normal” only the GSM STATUS LED will be ON. If the GSM Signal is
below the requested level, this LED will blink. The MS comm LED is showing the status of the incoming
call (If somebody dials the phone number assigned to inserted SIM card). The MS comm LED presents
the status of the calls started from the device connected to the communicator (Alarm system,
telephone device, etc).
If some fault is valid, red TROUBLE will lit continuously, while green LED shows the cause of the fault
with blinks
