Cavicel HDC is a non-resettable line-type heat detector (linear heat detection cable) that detects heat anywhere along its length – unlike a point detector, it is a continuous detector. It consists of two copper-covered steel wires insulated with a thermosensitive polymer; at the rated temperature the insulation melts, the conductors short-circuit and generate an alarm signal. The cable complies with EN 54-28 (non-resettable line-type heat detectors); reaction-to-fire class Eca (EN 13501-6). Applications: pipelines, storage tanks, cable trays, aircraft hangars, control rooms, warehouses, bridges and tunnels, mines, cooling towers and escalators. The cable is fixed at least every metre with clips (e.g. a T-clip) that must not damage or overtighten it. HDC-105 has an alarm temperature of 105 °C (±10 %), a black sheath and a maximum ambient temperature of 60 °C.
