Abstract:

A vehicle security system including a key switch, a first relay, a second relay, a first timer, a second timer, a warning device, and a push-button switch. The key switch activates and deactivates the system. Once the key switch is in an operative position and the system is activated, the vehicle's ignition switch in an operative position activates the second relay. Operation of the second relay, or of a vehicle door switch, activates the first relay which starts the first and second timers. The first timer initiates a first timing delay and, at the end of this timing delay, activates the warning device. The warning device warns the driver that the alarm sequence has been initiated. The push-button switch initiates an engine standby mode. The second timer initiates a second timing delay and cuts off the engine unless a standby mode is initiated before the end of the second timing delay.
