Fiber Defender - Model FD341/FD342 - Fiber-optic Intrusion Detection System Datasheet

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.
