Hi all, 
  
I have a Europlex Signet 100 installed and have just added a GSM module to the system. When an alarm is activated, notification is sent via GSM to my phone and it all seems to be working fine. 
  
When I try to send a command to my system from my phone via text eg to carry out a full set or to view the system status, nothing happens. according to my phone, the text was delivered but nothing happens on the system. 
  
What am I doing wrong with this? Have I missed a setting somewhere along the line?. 
  
My system firmware is v 1.0.0 and the firmware version on GSM module is v 1.1 
SMS Auth is set to caller id only. 
  
Any Suggestions would be appreciated. 
  
Thanks
