This is the advanced version of our Z4 Ultra & Z4 Farsi apps. You could control up to 8 compatible intruder alarm systems with this app. If you want to control 1 system however, its simpler to use Z4 Ultra or Z4 Farsi instead.
For those who havent used our apps, this app sends predefined SMSs to compatible GSM switches and alarm systems. So you dont need to type the SMS content.
