MOTOR VEHICLE ELECTRONIC SECURITY ALARM SYSTEM USING SEQUENCE CONTROL ARMING
First Claim
1. In a motor vehicle having a hood member, a trunk member, a plurality of door members, exterior lights, a horn, and an electrical power supply, an electronic security alarm system comprising:
- a plurality of switch means each located at a corresponding one of said vehicle members, each said swiTch means being normally in a first position indicating that the corresponding member is in closed position and being actuable to a second position whenever the corresponding member is opened;
arming means operatively associated with a key-actuated lock of the motor vehicle and responsive to the actuation of a key in the lock to provide an arming signal for arming the security alarm system;
a plurality of locking means each associated with a corresponding one of said door members and of said hood member and responsive to said arming signal and to the first position of the corresponding switch means for locking the corresponding member in its closed position;
control means operatively coupled with said arming means and all said switch means for providing a control signal, said control means comprising first control circuit means for providing said control signal in response to said arming signal and to actuation of the switch means associated with the hood member from its first to its second position, second control circuit means for providing said control signal in response to said arming signal and to actuation of the switch means associated with the trunk member from its first to its second position, and third control circuit means for providing said control signal in response to said arming signal and to actuation of any one of the switch means associated with the door members from its first to its second position provided that all said door member switch means have been previously actuated to their respective first positions;
timing means responsive to said control signal and electrically connected to the exterior lights and the horn for pulsing the exterior lights and horn with electrical power from the electrical power supply in response to said control signal; and
a distress switch operatively coupled with said locking means and said control means, said distress switch being located within said vehicle and actuable by an occupant of the vehicle to actuate both said locking means and said control means independently of said arming means and of all said switch means whereby to prevent unauthorized entry into the vehicle and to pulse the exterior lights and the horn.

Abstract
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.
