Upon receipt of the signal from the Sensors and Transmitter Unit the Receiver Unit activates a relay which causes a MIWU/lnterrupt. The interrupt service routine then waits for 10 seconds before reacting to the signal. This time is allowed to disarm the Security/Monitor- ing System. The Time Keeping Routine is used to caculate the delay and if the user disarms the System by toggling a switch the signal is ignored. Otherwide the Non-Volatile Storage Routine is executed to read the telephone number and this information is passed on to the Auto-Dialer Unit. The Auto-Dialer Unit dials the number and looks for a re- sponse over the telephone line. If however, there is no re- sponse, the Receiver Routine times out after a minute and tries the same number again. The number of trials can be modified in software and the time out period can also be changed. In the ASM System the number of trials is two. With slight modification the Auto-Dialer Unit can be made to dial a different number during the second attempt. The real time and date of occurrence of the event is stored in the NMC9306 along with the outcome of the telephone call. This routine keeps track of the non-volatile memory capaci- ty and if it overflows, it prompts the user on the terminal of the same. The user is given the choice to overwrite the non- volatile memory or replace the device. |
