Electronic security alarm system with sequence controlled switching on for motor vehicles

摘要

A security alarm system for motor vehicle wherein in response to an unauthorized entry into the vehicle or the opening of the hood or the trunk, an alarm comprising the exterior lights and the horn is energized. The system provides means for arming the system by a vehicle occupant turning a key in either of the front door locks. If one of the switch means responsive to either the doors, hood or trunk is actuated to indicate that said door, hood or trunk is open when the system is being armed, the system will not energize the alarm due to that violation until the switch means is subsequently reactuated. Additionally, the system provides for a distress actuator located within the vehicle and accessible to an occupant. Whenever the occupant is faced with a danger, he may actuate the distress switch thereby instantly securing the vehicle and sounding the alarm.
