  • Aircraft security alarm system
    Patent number: 7417542
    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.
