Fiber optic security system for sensing the intrusion of secured locations
First Claim
1. A security system for detecting intrusion at a plurality of predetermined locations having movable members which must be moved in order to intrude into said location, said system comprising:
- an optic fiber sensor fiber;
a plurality of sensors disposed at said locations contacting said optic sensor fiber, said sensors detecting movement of said moveable members and attempted physical intrusions at said locations and generating intrusion signals when one or more sensors are activated thereby;
a processor in communication with said sensor fiber for receiving said intrusion signals from said activated sensors and determining the location of each activated sensor;
a communication output operatively associated with said processor for communicating an identification of each activated sensor and the location of each said activated sensor; and
said sensors being disposed adjacent said moveable members in a non-contacting manner, and said sensors detecting a predetermined movement of said moveable members from a secured position to an unsecured position whereby intrusion signals are generated without physical connection between said sensors and said moveable members.

Abstract
A sensor for a security system is disclosed to detect intrusions at one or more predetermined locations wherein each location includes a moveable member which must be moved in order to intrude the location. The system includes a fiber network routed in close proximity to one or more locations. The sensor comprises a sensor housing for being disposed at a location to detect a predetermined movement of the moveable member from a secure position to an unsecured position, and means for mounting the sensor housing in a stationary position at the location without a physical connection to the moveable member. The sensor housing includes a fiber inlet and a fiber outlet, and a fiber chamber for receiving a predetermined sensor fiber of the fiber network being routed through the sensor housing. The sensor has a sensor actuator for engaging the sensor fiber to generate an intrusion signal upon detecting predetermined movement of the moveable member, and causing the intrusion signal to be transmitted along the sensor fiber to a processor whereby the intrusion and location of the intrusion may be determined by the processor. Preferably, the sensor includes a magnetic actuator having a magnetic attraction to the moveable members whose interruption causes activation of the sensor and generation of the intrusion signal.
