Abstract

An aircraft security alarm system uses proximity sensors mounted in adjacent pairs to any access area into an aircraft, The proximity sensors are connected electrically to a battery-powered control box with a miniature LED remote indicator light to identify that the system is activated. When any door or cover over an access area is moved, opened, or otherwise accessed, a switch in one of the pair of proximity sensors detects the movement. The proximity sensor sends a signal to the control box, which in turn triggers a high decibel/high pitch siren/horn that sounds indefinitely until the system is disarmed via a wireless remote control.

Claims

1. An alarm security system for small aircraft to protect all openings into the aircraft, the system comprising:

a control box powered by an electrical source of power;

a remote control mechanism communicating with the control box for activating and deactivating the system;

a remote indicator light connected to the control box by an electrical connector, the indicator light being turned on when the system is turned on and the indicator light being turned off when the system is turned off;

a noise making device connected to the control box by an electrical connector;

a series of pairs of proximity sensors each of the pairs comprising two elements at least one of which has a means to detect a proximal relationship with the other of the pair of proximity sensors and a proximity sensor electrical switch communicating with the means to detect a proximal relationship, the electrical switch connected by an electrical connector to the control box, at least one of the pairs of proximity sensors positioned at each opening into an aircraft body, the opening having a movable opening cover, with a first proximity sensor of the pair of proximity sensors attached to an edge of the movable opening cover adjacent to the opening and a second of the pair of proximity sensors attached to the body of the aircraft adjacent to the opening and adjacent to the first proximity sensor so that moving the opening cover to expose the opening causes a distancing between the pair of proximity sensors to activate the proximity sensor switch to signal the control box to activate the noise making device to make a continual alarm noise as long as the system is activated.

2. The system of claim 1 wherein the electrical source of power comprises a battery normally used in the aircraft.

3. The system of claim 1 wherein the electrical source of power comprises a battery independent of an aircraft electrical system.

4. The system of claim 1 wherein a first of a pair of proximity sensors is attached to a door of a cockpit of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

5. The system of claim 1 wherein a first of a pair of proximity sensors is attached to a movable window of a cockpit of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

6. The system of claim 1 wherein a first of a pair of proximity sensors is attached to an engine compartment hood of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

7. The system of claim 1 wherein a first of a pair of proximity sensors is attached to a door of a storage compartment of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

8. The system of claim 1 wherein a first of a pair of proximity sensors is attached to a door of a luggage compartment of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

9. The system of claim 1 wherein a first of a pair of proximity sensors is attached to a canopy over an opening of the aircraft and a second of the pair of proximity sensors is attached to a body of the aircraft adjacent to the first of the pair of proximity sensors.

10. The system of claim 1 wherein the remote control comprises a wireless combined key fob and remote control with at least two buttons including a system activating button and a system de-activating button.
