Optex Fd508 White Backround Picture 165Px V2

Product Details

The FD508™ Fiber-Optic Intrusion Detection System is an all-new fiber-optic perimeter sensor. The system detects intruders using a fiber-optic sensor that is deployed on the perimeter. For fence-protected perimeters, the sensing fiber is installed on the fence inside specially designed UV resistant polyethylene conduit.

The FD508 incorporates Fiber SenSys’ proprietary and patent-pending technology that has been successfully deployed in thousands of sensors throughout the world, in a versatile fiber-optic sensor. The FD508 detects intruders attempting to climb or cut through fences using a proven high-security technology. Sophisticated algorithms distinguish between actual intruders and “nuisance alarms” that might be caused by wind, wildlife or other environmental conditions. The fiber-optic sensor works by measuring laser signals resulting from potential intruders who vibrate the structure to which the fiber is attached.

When the FD508 detects intruders, it sends alarm messages to a head end, and also switches relay contacts that can be used to manage lights, cameras, sound alarms, etc. The FD508 monitors up to eight different sensing fibers (zones). Each sensing fiber can be installed up to 800 meters (2,624 feet) in length for maximum perimeter protection.
