8.3.10 SMS authentication
In this display, it is possible to set incoming message authentication
so that others cannot send SMS messages to the control system.
There are three methods of authentication:
• Via phone number
• Via PIN code
• Both (both via phone number and PIN code).
Phone number
SMS messages are only accepted from specially selected
telephone numbers.
PIN code
Only SMS messages beginning with the correct PIN
code are accepted.
The following SMS messages are received:
• ACK
Acknowledges an alarm SMS so that it is not passed on to the
secondary number.
• ALARMRESET/RESETALARM
Resets hanging alarms. Same as resetting via the operating
panel for CU 362.
• GETALARMS
Sends an alarm SMS for every alarm.
• STATUS or STATUS1
Returns a system status SMS message.
• AUTO
Changes from interlock to automatic operation.
• INTERLOCK
Changes to interlock, that is a type of stop.
• FORCERELAY

• RELEASERELAY
Releases the user-defined relay.
• SIGNALLEVEL
Returns signal strength for GSM modem.
• GPRS STATUS
Obtains the IP address from the GPRS connection.
• HELP or ?
Sends a list of commands.
• AOx y
x is the number of the user-defined output (1 to 3).
y is a number between 0 and 100 and is the setpoint for the
output.
The space between x and y is important to make the
function work.
Example
When a user receives an alarm SMS, it must be acknowledged. If
an acknowledgement is not sent, the alarm SMS is sent to another
user.
The PIN code is also used for the interlock function.
