User Manual
Description:
The GSM-SWITCH is a Single Output Relay system with normally open and closed contacts and provides a
low cost solution for a wide range of applications only requiring a simple GSM Switch, but with a 20 amp
rated Relay on board for switching high currents such as Heating and Lighting circuits and has internal
time clocks that can be programmed in several time zones.
The system has the flexibility to have a separate internal power supply connected on board if required and
therefore can be supplied with or without this facility
A Battery back up on board provides not only an 8 hour continuous of operation of the system but will
send a power down or power restored alerts in the event of power failure.
In addition the GSM-Switch can be ordered with our without an R.F Radio Control Receiver and
Transmitters as required which can mirror the GSM Functions.
As with most GSM Remote systems the unit is activated by calling its cell phone number and the system
will identify the number as authorized and then, will reject the call without answering and switch on the
device connected to it. And therefore there is no call costs involved when controlling the unit via voice call,
only when controlling the system via SMS
The system is able to load up to 250 numbers in the white list as authorized users and the single output
relay can be programmed to switch on for a pre-determined length of time whenever the GSM-SWITCH is
called, alternatively the output relay can be permanently switched on or off by sending the GSM-SWITCH
a text message without effecting the default settings when Called
Alternatively you can program the unit by using the Software programming package supplied with the
system and explained in the separate Soft-ware Manual enclosed.
Requirements:
A mobile phone Network SIM card with sufficient credit to send confirmation text messages when initially
programming the GSM-SWITCH, the unit accepts any Global Network SIM Card as the system is fitted with
a Quad Band Modem.
Power Supply
If the system is not being used with the on board mains Power supply the system will need a Regulated
12 Volt Power supply which has its own input connection on board and separately fused for Protection.

Installation:
The GSM-SWITCH comes with an IP65 Enclosure and can be mounted internally or externally as required
and if supplied with an Internal Power supply you will only require to provide mains power 110-240 directly to
the unit and connect as identified as Earth/Power and Neutral on the control board of which is provides fused
mains protection to the device being controlled.
The low Voltage output is connected to the main controller and further fused for further protection of the
system.
As the GSM-Switch has a 20 amp rated relay on board and 20 amp terminals it is therefore possible if
controlling say 3 KW devices and only require taking a four core Mains cable to the device and feed the
controlled device direct as per the diagram explanation, thus saving the time on installation costs and
providing a more tidy installation and a simple plug and play solution.
Power Input to Switch
Power Output to

Connections Mains Power Input and Output with Mains Power Supply on Board
This provides a very simple solution for wiring and connecting up and controlling Mains devices directly
from the GSM Switch and having fused protection both ends and a Power down Alert facility.

Setting up and Programming
Once you have installed the GSM-SWITCH and make the required connections to the device to be
controlled the SIM Card can now be installed in the Holder as indicated in the schematic drawing and the
Power Supply can be connected and switched on.
Note: You must remove the PIN request from the SIM before inserting it in the unit; otherwise the device
will not work. In order to do so, insert the SIM in a phone and disable the PIN Request and the Voicemail
function as this can also affect the system with some networks which can activate the voicemail before the
system has read the incoming telephone number!
On most SIM Card Network systems now the PIN requests are disabled but it is worth checking first and
removing the Voice Mail function.
The Signal Led (Green) on the board will oscillate infrequently until it finds and logs on to the Network and
will then flash every 3 seconds constantly and if does not happen then the unit has not logged on and it may
be required to use an extension antennae or alternative network provider or re-seat the SIM CARD.
At this stage the visual bank of LED signal indicators immediately above the Network LED will also illuminate
to indicate the system has logged on to the Network and will indicate either one to four bars of signal
strength
Once the system has logged on the Network the one thing you also can do is to establish is the “actual
Signal Strength”at the Location of the Installation to secure constant signal strength for the reliability of the
GSM-SWITCH and this can be done by simply sending the following SMS Text message to the unit.
*PSSW*SGH? And this is the only command that does not require a password and you will
receive the following similar SMS Message subject to the actual Signal strength
Signal strength < 18 >
This Signal Strength range can typically vary from “3-31” of which it is suggested that a consistent Signal
Strength acceptable should be at least 12 and above as the signal network strengths can vary dramatically
and a typical acceptable signal strength would be circa <10>-<15> and in the even of a Signal strength
below <7 > it would be suggested You install and external antenna to improve the Signal strength.
Programming the GSM-SWITCH
The GSM-SWITCH is programmed by either sending it SMS text commands from a mobile phone or using the
soft-ware provided and explained under separate cover.
The password command must pre-fix all SMS text commands and the default password can be changed to
any other 5 digit number of which must be noted as if lost or forgotten the only resolve is for the unit to be
reset by the factory.
Remember that all SMS text commands must always be sent in CAPITAL LETTERS and DO NOT add
spaces or any other characters otherwise the system will simply ignore the text messages and not perform
the commands.
Programming via SMS and Default Command
The GSM-SWITCH is pre- programmed and can be controlled by sending certain SMS Text Messaging to the
unit and is password protected with a factory default setting of five digits preset at *PSSW12345 and this
prefixes any commands to the unit and the unit is also set up as factory default to initially accept any
incoming telephone call which will activate the relay for one second, again which is set as factory default.

GSM-SWITCH –USER MANUAL –Rev. 1.7
The security mode would normally be activated after all the authorized numbers are stored into the system
and confirmed as correct as if any of the numbers have been incorrectly stored that persons number will no
be able to access the system.
Changing the Password
It is possible to Change this password to another 5 digit number by sending the following SMS Text message
to the unit and we assume the new Password is 54321
*PSSW12345*NPW=54321
You will receive the following message back from the unit to confirm the password has been changed
NPW=54321
The new password is now *PSSW54321
Checking Signal Strength
*PSSW*SGH?
The system will now send back a report to indicate the Signal Strength at the location of the GSM-SWITCH
and you will receive a similar message as follows.
SIGNAL STRENGH < 14 > which indicates a mid range of Signal Strength and is acceptable to maintain a
constant network as the networks will vary and can drop as low as < 7 > and any lower the unit can well log
off the network and Latch off the Relay if active and gives the indication that the unit is faulty when it is only
subject to a low or loss of Signal Strength.
In this instant the unit will consistently search and communicate with the network until it have re-
established a network link and log back on and appear as an intermittent fault and If this continues to
happens on a regular basis it is suggested you install an additional External Antenna.
Setting up the Security mode.
This function as explained can be operated in two modes of security which can be set as desired and the
factory default is “Open Mode” meaning any person who has access to the actual SIM Card telephone
number of the unit can operate the system and this is usually only used for setting up the system or for low
security applications based on applications of convenience.
The other mode of operation is the “Security Mode” which only allows the persons who have their
telephone numbers entered into the security list of the unit to access the system and this is usually also
done once all the pre-programming of the telephone numbers has been programmed into the system and
the Latch times set.
This mode of command would normally be done once all the telephone numbers have been programmed into
the system and you would then set the “Security Mode” and to program this you would send the following
SMS Text message to unit.
*PSSW54321*SSM=ON and the unit will return the following SMS Text Message.
SSM=ON and the “Security Mode” is on
To set the system back to “Open Mode” you would send the following SMS text message to the unit
*PSSW54321*SSM=OFF and the unit will return the following SMS Text Message.
SSM=OFF and the “Open Mode” has been set to factory default.

Setting the Latching time for the unit when called
The GSM-SWITCH can be programmed to latch the Relay from a period of from 1 second up to 12 hours
when called and this allows a vast range of flexibility for many applications from Automatic gates to
switching on heating and lighting and remote re-setting of servers etc.
The unit comes preset to latch the relay for a period on 1 second and to change this latching period time to
say 1 hour you would use the following programming command which is always calculated in seconds with 5
digits and therefore the command would be sent as 03600.
To pre-program to unit to latch the relay for 1 hour when called you would send the following SMS Text
message to the unit, using the new password *PSSW54321
*PSSW54321*RLY=03600 and the unit will return the following SMS Text Message.
RELAY SET - 03600 and the Relay of the unit will now latch for one hour whenever the unit is called
(Subject to authorization of the number if Security Mode Set)
In addition to the pre-programmed latching time when the unit is called, it is also possible to temporary or
permanently latches the Relay via SMS Text message without affecting the existing programming function
when the unit is called.
If it is required to latch the relay temporarily for say 2 hours you would use the following SMS text command
and again based on seconds.
*PSSW54321*RLYT=07200 and the unit will return the following SMS Text Message.
RELAY TEMP 07200 and the relay has been temporarily latched for 2 hours as set in seconds.
If you require latch the Relay permanently “ON” and back “OFF” again this can be done by using the
following SMS Text commands.
To latch the relay permanently “ON” you would send the following SMS text command to the unit.
*PSSW54321*RLYP=ON and the unit will return the following SMS Text Message.
RELAY <P> ON
To latch the relay permanently back “OFF” you would send the following SMS text command to the unit.
*PSSW54321*RLYP=OFF and the unit will return the following SMS Text Message.
RELAY <P> OFF
If you need to check the status the Relay and what mode it is you can send a SMS Text request using the
following command.
*PSSW54321*RLY? And the unit will return the following SMS Text Message. (Example assuming Relay is
still part active after programming to be on for 2 hours and 1 hour remaining.
RELAY ON 03600
If the relay has been programmed as permanently on the unit will return the following S.M.S Text message.
RELAY ON <P>

If the Relay is inactive the unit will return the following SMS Text message.
RELAY OFF
SMS Report after latching the unit by calling the unit
It is possible to receive a text message whenever the Relay is latched via Phone Call which will report both
Relay On and Relay Off to the user that has call the unit and only practical for certain infrequent
applications and the factory default for this function is off.
To enable this function you would send the following SMS text message to the unit.
*PSSW54321*RLYM=ON and the unit will return the following SMS Text message
RLYM-ON and the unit will return both Relay On and Relay Off status SMS Text messages when called.
To turn this function off you would send the following SMS Text Message to the unit.
*PSSW54321*RLYM=OFF and the unit will return the following SMS Text Message
RLYM=OFF and this function is now disabled.
Programming in the administrator number in the system
It is possible to program 1 administrator number into the system that will be recognized as authorized
number that have programming access to the system as well as activate the device it is connected to.
To add 09876543210 as the administrator you would send the following SMS text message to the unit
*PSSW54321*ADM1=09876543210
This administrator number is the telephone number that will receive the Power Down and Power
Restored messages.
Programming in the authorized telephone numbers in the system
It is possible to program up to 250 Land line or Mobile Phone Numbers into the system that will be
recognized as authorized numbers that can access the system and activate the Device it is connected to.
All telephone numbers can be programmed into the system using only the 7 digits of the telephone number
as the system will scan the numbers of the last digits and accept and authorize that number to allow access
to the system and will then reject the incoming call and activate the Relay as set and operate the device it is
connected to.
Any Unauthorized numbers calling the unit will result in the system rejecting the call and refusing access to
the system or the device the system is connected to.
It is Possible to program up to 5 telephone numbers Into the system using the same SMS Text command
and you would use the following command to enter the first 5 examples of numbers, based on using the last
7 digits of the number.
*PSSW54321*CLD01=1212121,CLD02=1313131,CLD03=1414141,CLD04=1515151,CLD05=1616
161 and the unit will return the following SMS Text Message.
CLD01=1212121
CLD02=1313131
CLD03=1414141
CLD04=1515151
CLD05=1616161
