Similar to the digital linear heat detection cables, the fibre optic linear heat detection cables can record temperatures along the sensor cables as a continuous profile, and can detect fire and overheat conditions over distances of up to 10km.

The Fibre Optic system uses a semi-conductor laser diode and revolutionary evaluation procedures to detect small temperature changes along the length of the cable with great precision and reliability.

Highly suited to long continuous cable runs, fibre optic linear heat detection is another weapon in the arsenal of detection products.
