SMS alarm is a very simple device. To send SMS it uses Siemens gsm phone and it has 5 inputs - it means that it can send 5 different SMS messages. For each sensor input we write SMS text that we wish to receive when alarm condition happens. Programing is done via PC and proper software that is available for download.

You have HEX file to burn into the PIC first. After that you connect ALARM to PC and work with
uploader. The uploader will import text of SMS messages that you with PDUspy program. You must
use EEPROM (24C512/515 - see circuit diagram for eeprom info), it cannot be replaced with
MAX232!!!
