Abstract

An alarm system comprises an armable circuit, an arming circuit adapted to pulse said armable circuit into its armed or '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' position and including a timer to activate said arming circuit after the passage of a fixed time period, a timer initiator for starting the timer into its timing mode, reset means to return and hold said timer in its initial or zero position only within said fixed time period to allow for a fixed or limited time for the reopening of doors and/or trunk without setting off the alarm, said armable circuit when in the armed mode being triggered by at least one automotive courtesy or dome light switch, hood switch, trunk switch and/or pressure sensitive seat belt interlock switch to complete the circuit allowing current to flow through said circuit to the automotive lights, horn, or other audible alarm device, a disarming circuit closed by the use of the door/ignition key to cause a momentary current to pulse said armable circuit into the disarmed mode.

Claims

1. An automotive alarm system comprising:

an armable circuit, an arming circuit adapted to cause a non-continuous current to pulse said armable circuit and cause said armable circuit to go into its armed mode, said armable circuit when in the armed mode being triggered by a sensing means to complete the circuit allowing current to flow to the automotive lights, horn, or other alarm device, and a disarming circuit which when closed causes a noncontinuous current to pulse said armable circuit into the disarmed or deactivated mode.

2. An alarm system comprising:

an armable circuit, an arming circuit adapted to cause a non-continuous current to pulse said armable circuit and cause said armable circuit to go into its armed or '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' position and including a timer to activate said arming circuit after the passage of a fixed time period, a timer initiator for starting the timer into its timing mode, reset means to return and hold said timer in its initial or zero position only within said fixed time period to allow for a fixed or limited time for the reopening of doors and/or trunk without setting off the alarm, said armable circuit when in the armed mode being triggered by a sensing means to complete the circuit allowing current to flow to the automotive lights, horn, or other alarm device.

3. An alarm system comprising:

an armable circuit, an arming circuit adapted to cause a non-continuous current to pulse said armable circuit and cause said armable circuit to go into its armed or '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' position and including a timer to activate said arming circuit after the passage of a fixed time period, a timer initiator for starting the timer into its timing mode, reset means to return and hold said timer in its initial or zero position only within said fixed time period to allow for a fixed or limited tiMe for the reopening of doors and/or trunk without setting off the alarm, said armable circuit when in the armed mode being triggered by a sensing means to complete the circuit allowing current to flow to the automotive lights, horn, or other alarm device, a disarming circuit closed by the use of the door/ignition key to cause a non-continuous current to pulse said armable circuit into the disarmed or deactivated mode.

4. The device of claim 1 wherein the armable circuit is made to send a pulse by a door lock actuator and the timer initiator is responsive to the sequence:

open door, door lock actuator being in the locked position, and closed door, said sequence indicating the exiting and locking of the vehicle from the outside.

5. The device of claim 1 wherein the armable circuit is made to send a pulse by a door lock actuator and the timer initiator is responsive to the sequence;

courtesy dome light door switch being '"'"''"'"''"'"''"'"'on,'"'"''"'"''"'"''"'"' both right and left door lock actuators being in the locked position; and

courtesy dome light door switch being turned '"'"''"'"''"'"''"'"'off'"'"''"'"''"'"''"'"' by the closing of the last of said doors whereby the system recognizes and arms when the door lock buttons are depressed and the operator is exiting the vehicle.

6. The device of claim 1 wherein the armable circuit is made to send a pulse by a door lock actuator and the timer initiator is responsive to the sequence:

right and left door lock actuators being in the locked position, pressure sensitive seat belt interlock switch recognizing the absence of a passenger or operator whereby the system recognizes and arms when the door lock buttons are depressed and the operator is exiting the vehicle.

7. An alarm system comprising:

an electrical circuit for powering automotive lights, horn, or other alarm device, means operated by the tape deck, spare tire, secured but removable object, or other accessory to automatically and continuously protect the same by holding the circuit in the open position, said circuit being closed by the removal of the tape deck, spare tire, secured but removable object, or other accessory from its installed position within the vehicle, and a door, ignition, or any key operated switch, wherein said switch must be in the '"'"''"'"''"'"''"'"'on'"'"''"'"''"'"''"'"' position to be deactivated and/or inhibit said circuit and permit normal authorized removal of said accessory from the installed position.

8. The system of claim 1 wherein the armable circuit includes a single pole, double-throw magnetic latching relay having two coils and requiring no power in the open or closed position.

9. The device of claim 2 wherein the timer initiator is responsive to the operation of a switch located within the vehicle which is operative to begin the time sequence.
