Optex Fiber Sensys Fd34 Series 165Px Visual

Product Details

Our sister company Fiber SenSys’ FD34X series Fiber Optic Intrusion Detection System offers high performance intrusion detection with modern features and communication options.

Designed for remote deployment with no power or communications needed in the field, the indoor and outdoor rated Fiber Defender™ Model FD341 Alarm Processing Unit (APU) 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.

Dual Zone Coverage Proven reliability
The FD342 provides independent dual channel operation, users can connect the sensor cable from two separate deployment locations. Dual-channel capability reduces the FD342's overall system cost and power consumption. Independent zone control allows for maximum versatility, such as a wall and a fence protection zone combination. The FD34x series also provides intrusion detection system control with communication options that include IP/XML capability.The FD34x series Digital Signal Processor (DSP) and electronics provides users an intrusion detection system that is immune to the effects of EMI, lightning, magnetic fields and radio frequency transmissions. Enhanced DSP capabilities filter out sensor cable signals from non-threat events such as wind, weather and small animals. Made in the U.S.A., the FD34x guarantees system performance and high reliability for perimeter security
