Pipelines Storage Tanks Cable Trays Aircraft Hangars Control Rooms Warehouses Bridges and Tunnels Mines Cooling Towers Escalators The HDC sensor cable detects heat anywhere along its length: it is a continuous heat detector unlike the standard point detector. The HDC sensor cable is composed by two copper covered steel wires, individually insulated with a thermosensitive polymer. At the rated temperature the polymer insulation melts, thus permitting the conductors to short-circuit and generate an alarm signal. Four temperature alarm levels are available: 68 °C, 88 °C, 105 °C and 138 °C. Ease...
