Linear Heat Detector Cable – HDC
- Linear heat detector cable is a fire detection technology that detects heat and temperature changes along its length.
- 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 of 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.
