Setting up system for the first time:
Please ensure the SIM card does NOT have a PIN number or is locked has been
ACTIVATED with the network provider, insert into SIM slot on the back (see
page 4) and power the unit up.
When the unit is first powered ON a mobile (cell phone) number must be set for
initial programming. This phone number is called the “Initial Owner”.
You must wait for the LED to be slowing flashing (EVERY 3 seconds) before
sending any commands. Please wait a few minutes, as the unit will set auto-
band and other details for the country.
IMPORTANT:
For all text commands, spelling and spaces must be strictly followed.
Country Code:
?? Is the country code and XXXXXXXX is the mobile number without the preceding 0.
Examples:
New Zealand = 64 (+64 and the number without the preceding 0)
If the users number is 0211893070 then Command = add user [phone]
Australia = 61 (+61 and the number without the preceding 0)
If the users number is 0412882900 then Command = add user [phone]
Singapore =0065 (+65 and the number without the preceding 0)
If the users number is 0412882900 then Command = add user [phone]
USA & Canada = 001 (+1 and the Area Code & Number)
If the users number is 412-555-1234 then Command = add user [phone]

!! NOTE !!
If a user sends a text message to the system, which is not an exact match with the
commands, the system responds with:
Sorry either that device does not exist or the message format is not understood, please
check the spelling and try again
If anyone other than a programmed user sends a text message to the system, the
system responds with:
Sorry you are not permitted to access this device
Setting up the first user (Once only command)
Command: Set user
Note: the unit will pick up the users number from the incoming text.
When the Initial user setup has been successful the system responds with:
“ Your number has just been added to the user list”
Note: The initial user could be the installer who would set the system up, add other users (Add
user page 8) and then remove his number (Remove user page 8).

8
Adding a User (Note: Setting up the first user page 7 must be done first)
Command: Add user +??XXXXXXXX (see Country Code page 7)
If the master is already in the list, the system responds with:
Sorry +??XXXXXXXX is already active and cannot be added twice, please check
the number and try again
If the number does not fit the checks, to confirm it is a valid number (all digits must be
numbers excluding the leading +), the system responds with:
+??XXXXXXXX does not appear to be a valid number, please check that there
are no letters or symbols in the number and try again
If the number does not lead with a +, the system responds with:
??XXXXXXXX does not appear to have the country code in international format
(e.g. +??...) please check this and try again
However if everything is fine, the system responds with:
The user number +??XXXXXXXX has been added to the user list
Removing a User
Command: Remove user +??XXXXXXXX (see Country Code page 7)
If you try to remove the only master, the system responds with:
Cannot delete the only master; if you would like to change masters add the new
one before removing the old
If the number sent is not currently on the list, the system responds with:
+??XXXXXXXX is not currently on the masters list so cannot be removed,
please check the number and try again
If everything is ok, the system responds with:
The user number +??XXXXXXXX has been removed from the user list
Adding a Administrator
Command: Add admin +??XXXXXXXX (see Country Code page 7)
The system responds with:
The number +??XXXXXXXXXXX has been set as the system administrator
If the admin has already been set, the system responds with:
The administrator number +??XXXXXXXXXXX has already been set
If an administrator number is set then this is the only number the system will except
commands from. Other user will be sent texts but CAN NOT send any commands.

case it will move the user from administrator to user.
The system responds with: This number has been changed from administrator to a user
Get a list of all the Masters
Command: User list
The system responds with:

+??XXXXXXXX +??XXXXXXXX +??XXXXXXXX …
Turn programmed numbers lookup on or off
Command: User lookup on (or) off (System default = On)
If User lookup is On the SMS-T2 will only respond to numbers that have been programmed
into the unit using the Master Add command as per above.
If User lookup is Off the SMS-T2 will respond to any number that sends the correct
command.
The system responds with:
The user lookup list feature has been turned on and the unit will only except
commands from programmed users
OR The user lookup list feature has been turned off and the unit will only except
commands from any users
PLEASE NOTE: Input changes will only be sent to users that have been programmed into the unit.
Text all programmed numbers on or off
Command: Text all on (or) off (System default = On)
If Text all is On the SMS-T2 will text all user that have been programmed into the unit with the
reply to the command.
If Text all is Off the SMS-T2 will only text the number that initiated the command with the
reply.
The system responds with:
All users in the list will now receive notification texts ( On )
OR Only the number sending the text command will receive notification text ( Off )
PLEASE NOTE: This command does not affect the inputs all Input changes will only be sent
to users that have been programmed into the unit.

When input1 is turned on output1 will turn on, when input1 is turned off output1 will turn off
When input2 is turned on output2 will turn on, when input2 is turned off output2 will turn off
Test finished
Get a list of the Inputs
