    FyreLine Digital Linear Heat Detection

    FyreLine Digital Linear Heat Detection Systems provide a cost-effective and reliable fixed temperature heat detection solution that is suited to a wide range of applications.

    FyreLine Digital Heat Sensing Cable is comprised of two tri-metallic conductors that are covered with advanced temperature sensitive polymers. The two conductors are twisted together and a protective outer sheathing is wrapped around them.

    Once the temperature sensitive polymer reaches its rated temperature it melts, causing the two conductors to come into contact. The resulting short circuit signals to the fire alarm control panel that a fire (or extreme heat) has been detected.

    Once a fire has been detected, or if the detection cable becomes damaged, the affected length of cable can be easily replaced; the damaged section can be removed and new section spliced in its place.

    Fyreline Digital Linear Heat Sensing Cable is available with temperature ratings of 68°C, 88°C, 105°C or 185°C..

    Digital Product Range

    PVC Coated Sensing Cable

    The standard coating used on Digital cables is made from PVC and is suitable for most environments. However, PVC should not be used when the cables are directly exposed to UV (sunlight) or hazardous chemicals (eg. hydrocarbons) for long periods, or for applications where they may be exposed to regular mechanical abrasion. Where the standard PVC is not recommended other materials/sheaths are available to provide a suitable solution.

    Nylon Coated Sensing Cable

    A Nylon coated cable is the common choice when hazardous hydrocarbons such as fuel oils, diesel, kerosene etc. are present. Nylon cables are coloured black and provide suitable UV protection when used in direct sunlight. Nylon is much tougher than PVC and therefore provides additional mechanical protection.

    Stainless Steel Braid Coated Sensing Cable

    Any of the above cables can be armoured by placing stainless steel braiding over the outside of the cable. This provides the ideal solution for areas where the cable may be accidentally cut or where it may be subject to mechanical abrasion.,/p>
