Fiber Optic
This product is best described as a continuous linear thermometer actively reporting temperature readings in realtime. The restorable linear heat detector is comprised of quartz fibers enclosed in a low smoke zero halogen jacket. Immune to all EMI and RFI, the fiber optic linear detector can be configured to offer custom alarm criteria and zone sizes up to 30,000 feet (10 + km) in length.
UL Listed Alarm Operating Temperature is programmable from 135 F (57C) to 235 F (113C).

FAQ's
Does splicing of the Fiber Optic Linear Heat Detector require any special tools or training?
Yes. Splicing of the Fiber Optic Linear Heat Detector requires fiber optic fusion splicing equipment. Anyone performing splices must be trained in their use.
Does the Fiber Optic Linear Heat Detector require replacement after a fire is detected?
Provided the detector is not exposed to temperatures exceeding 302° F (150° C) for a period of over 60 minutes, the detector does not require replacement. Should the maximum exposure temperature be exceeded or is unknown, then replacement of the exposed section is recommended. The replacement fiber optic detector must be fusion spliced to the unaffected existing fiber optic detector.
How is the Fiber Optic Linear Heat Detector terminated?
The beginning of the Fiber Optic Linear Heat Detection Cable is fusion spliced to an E2000 pigtail for connection within the controller enclosure. For single ended configurations (similar to Class B) the end of the Fiber Optic Linear Heat Detector is terminated with a 65 foot (20M) service loop and then capped. For double ended configuration (similar to Class A) the end of the Fiber Optic Linear Heat Detector is fusion spliced to a second E2000 pigtail for connection within the controller.
Is a separate interposing fiber optic cable required to connect the FiberSystem 8000 controller to the Fiber Optic Linear Heat Detector?
No. Digital linear heat detectors require interposing copper cable to traverse non-protected areas. For Fiber Optic Linear Heat Detectors this is not the case. The same Fiber Optic Linear Heat Detection Cable is run from the controller through non-protected areas into the protected area. In programming, the Fiber Optic Linear Heat Detection Cable in the non-protected area can be configured as a non-detecting section of the overall loop.
What is the listed spacing for the Fiber Optic Linear Heat Detection Cable?
The UL-listed spacing for the Fiber Optic Linear Heat Detector is 50 feet on center.
