Alarm is a function that can be triggered only by button. When alarm is triggered, event with IO ID 236 is generated. After that SMS and call can be processed.
Data sending follows this order:

  1. Record via GPRS
  2. SMS Event
  3. Call

Also added special parameter “SMS Sending method”. This parameter describes when SMS event should be sent. If selected method is “after GPRS fail”. At first device tries to connect to GPRS context using configured APN. If it does not connect device sends sms event to configured number. If method is “always” sms will be sent at two possibilities: when GPRS failed or records are sent to server.
