Fiber Optic Linear Heat Detectors (FO LHD)

Specifications Overview

Optromix manufactures various fiber optic products. We can accommodate your special requirements and design a fiber product catered specifically for your needs.
Fiber Optic Linear Heat Detector LHD-1-4

Fiber Optic Linear Heat Detector LHD-1-4

LHD-1-4 detects fires along a fiber optic cable, based on parameters selected via user interface. Determination of the fire location allows to identify the area (room) where fire is detected, even when the cable is destroyed as a result of the fire. Two cable types can be used:

– with LSZH jacket – for operating temperatures up to 80°C

– with silicone rubber jacket – for operating temperatures up to 200°C
