Abstract

A multi-function security system for monitoring access to a protected area such as a vehicle. The system has a self-diagnostic capability for detecting defective sensor or trigger devices and bypassing such devices to allow the system to be armed. The system includes audible and visual message capability for providing an indication when the system is disarmed that an intrusion was attempted and identifying the particular intrusion point. Multiple levels of security are provided by programming the disarming event as either entry of a code via a remote transmitter or entry of the code via the transmitter and then entry of an authorization code manually via a key pad. Other features include a reset feature activating the alarm when power is removed and restored unless a predetermined switch is active, programmable door lock and unlock signals to adapt the system to a particular power door locking and unlocking system, programmability of the alarm siren code and duration, automatic activation of the vehicle courtesy light when the system is disarmed, selective disabling of the system audible indications of arming and disarming, and programmable sensor or trigger polarity.

62. The security system of claim 61 wherein said user-personalized pattern of audible sounds take the form of distinctive pattern of audible "dots" and "dashes."

63. The security system of claim 51 wherein said means for generating alert signals comprises means for generating audible alert signals, and wherein said controller further comprises means for generating alert control signals which determine the duration of said audible alert signals during an alarm condition, and user programmed means activated during a system programming mode for receiving user-programmed duration signals which determine the duration of said audible alert signals during said alarm condition.

64. The system of claim 51 further comprising audio signal means for generating a first audio signal indicative of the armed mode when the system is toggled from the disarmed mode and a second audio signal indicative of the disarmed mode when the system is toggled from the armed to the disarmed mode, and further comprising user programmable means operable during a system programming mode for selectively disabling said audio signal means, whereby said system may be selectively programmed to toggle between said armed and disarmed modes without providing said audio signals.

65. The security system of claim 51 wherein at least one of said sensor devices comprises means for providing an output signal state having respective high and low voltage states, and wherein a particular one of said output signal states represents said sensor activated signal for said sensor device, said system further comprising means for causing said sensor device to generate said sensor activated signal during a system programming mode, and wherein said monitoring means of said controller is programmable during said system mode to recognize said particular output signal state as said sensor activated signal.

66. The security system of claim 63 wherein said vehicle includes one or more vehicle doors, and said at least one of said sensor devices comprises a door trigger for indicating the open/closed status of at least one vehicle door.

67. The system of claim 51 wherein said vehicle further comprises a power door locking and unlocking system for locking the vehicle door or doors in response to a "door lock" signal and for unlocking the doors in response to a "door unlock" signal, and wherein said controller further comprises means for providing said "door lock" signals to said power locking and unlocking system in response to the toggling of the system from the disarmed mode to the armed mode, means for providing said "door unlock" signals in response to the toggling of the system from the armed mode to the disarmed mode, and programmable means for selecting the duration of said "door lock" and "door unlock" signals during a system programming mode to match the security system to the particular power door locking and unlocking system.
