Method for transfer of notifications in system for transfer of alarming notifications (STAN) “Selena” includes in particular receiving-control device under control of micro-controller (PPK), retranslator (RT), station connection device (PSS), control panel of centralized observation on which panel connection device (PSP) is placed, this is intended for operation with retranslators and computer. The method includes exchange of information packs between the control panel of centralized observation, panel connection device, station connection device, retranslator, reception-control device, exchange of information packages between the sections of the system. Reception-control device as reply to request generates information packs. Transfer of information by telephone lines is performed with use of method of phase manipulation. At the beginning of information exchange retranslator generates random number, enters it to permanent memory and transfers it to receiving-control device that stores that random number in permanent memory. At each exchange of information packages retranslator compares remembered random number to that obtained from the receiving-control device and makes decision on fact of falsification of device of absence of falsification. |
