WAYS OF SYSTEM CONTROL
Example:
Number of contact (variant) «Armed»:
+380501234567p0000#1
where
+380501234567
– number of SIM-card of GSM-system
p
– symbol of pause in number entering
0000
– current PIN-code of the system
1
– command of arm mode activation
- command of end call by the system
Modern mobile phones allow choosing some keys for automatic call to a number from their phone book
(quick number dialing). Using this function and contacts-commands previously saved in the format described
above, you can significantly simplify the control of GSM-system.
ATTENTION!
You should remember that the PIN-code of GSM-system will be available in case of stealing a mobile phone.
2.3 System control using SMS
To operate system using SMS send it to number of SIM-card installed into GSM-system..
ATTENTION!
To avoid unauthorized system control any SMS sent to the system must start with the following command:
PIN:xxxx
where
xxxx
– four PIN-code digits (every from 0 to 9)
Any message not including this text at the beginning will be deleted by the system without processing.
After receiving of SMS and command completion GSM-system will send report about command
completion to the number from which this message was sent. If report was not received, this mean that there
was a mistake in the text of SMS-command (wrong PIN-code, syntax error in command text or there are
some problems with mobile operator’s SMS-server).
If it is necessary to send SMS-report about this command completion to other phone number enter in the
text of SMS (see item 2.3) with the required command:
ECHO ''+xxxxxxxxxxxx''
where
+xxxxxxxxxxxx
– phone number in format (+380671234567)
Example:
PIN: 0000 arm echo ''+380671234567''
In this case system will send SMS-report ARM OK to the 380671234567.
ATTENTION!
In most cases in conditions of roaming or when sending SMS via Internet command “ECHO” is necessary
for correct delivery of SMS-reports by the system.
Note
Any SMS without PIN-code is deleted without its processing.
The receipt of SMS with wrong PIN-code will be accepted by system as PIN-code fitting about what it will
inform with correspondent SMS (see item 4.1-4.4).
When system received SMS with wrong PIN-code it will delete all incoming SMS during 2 minutes without
their processing
