Fiber Defender - Model FD341/FD342 -Fiber-optic Intrusion Detection System
Designed for remote deployment with no power or communications requirements in the field, the indoor and outdoor rated Fiber Defender® Model FD341/FD342 Alarm Processing Unit (APU) is a next-generation alarm processor unit that utilizes insensitive fiber-optic cable in addition to sensing fiber. The use of insensitive lead-in cable allows the APU to be located up to 20 kilometers away from the protected zone. Movement or vibration in the physical environment causes the sensing fiber to report back to the APU that there is a disturbance. This feature makes the FD341/FD342 an ideal platform for protecting areas in or near EMI/RFI fields, areas of extreme temperatures, high humidity climate or corrosive environments.
The FD341 is a single-channel model, and the FD342 is capable of supporting two separate zones of fiber-optic cable. Each channel in the APU can be programmed and tuned separately using the Fiber SenSys SpectraView™ tuning and software. Each FD342 channel supports up to 5 km (16,400 feet/3.1 miles) of sensor cable. The FD341/FD342’s digital signal processing enables detection and analysis of sensor cable. The Digital Signal Processor (DSP) also provides discrimination between natural phenomena and intrusion attempts. Using a proprietary algorithm, the FD341/FD342 monitors wind effects and actively optimizes the system response to compensate. Two alarm relay outputs are provided in each FD341/FD342 channel - a normally-open and a normally-closed set of relay contacts. Corresponding relays change state when the APU detects a sensor cable alarm condition. Also included is an RJ-45 connector for TCP/IP communication.
