ABSTRACT:
A microprocessor controlled automobile security system provides several features for enhanced operability. The system allows a receiving unit to learn a plurality of operating codes from a plurality of uniquely coded transmitters with which it can operate, thereby allowing each transmitting unit to be sold separately from each receiving unit. The system also allows for an operator to personally set the threshold at which a signal detected by a shock detector will result in an alarm being triggered. The system is further selectively operable in either a manual arming mode or a passive arming mode. The system also allows selective operation in either a full current sensing mode in which either a detected shock above an absolute threshold or a .DELTA. threshold, or current flow above a predetermined level, will trigger an alarm system or operation in a shock and current integration mode in which if a detected current exceeding a predetermined threshold and a shock above an absolute or .DELTA. threshold is required to trigger the alarm or a much greater current flow is required to trigger the alarm system.
