Protectowire PHSC-155 Linear Heat Detector

Protectowire linear heat detectors are proprietary cables that detects heat anywhere along its length. The sensor cables are comprised of two steel conductors individually insulated with a heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with an outer jacket suitable for the environment in which the detectors will be installed.

Protectowire are fixed temperature digital sensors and are therefore capable of initiating an alarm once its rated activation temperature is reached. At the rated temperature, the heat sensitive polymer insulation yields to the pressure upon it, permitting the inner conductors to move into contact with each other thereby initiating an alarm signal. This action takes place at the first heated point anywhere along the detector’s length. It does not require that a specific length be heated in order to initiate an alarm nor is system calibration necessary to compensate for changes in the installed ambient temperature.

Protectowire linear heat detectors provides the advantages of line coverage with point sensitivity. Protectowire linear heat detectors ideally suited to industrial high risk hazards as well as many types of commercial applications, protectowire linear heat detectors has unique advantages over other types of detectors, especially when difficult installation factors or severe environmental conditions are present. When used with a protectowire FireSystem control panel, the detectors will activate a display, showing the location of an over heat or fire condition anywhere along its length. The detectors also meets intrinsically safe standards and are FM approved for Class I, II, or III, Div. 1, applicable Groups A, B, C, D, E, F & G hazardous areas, when the appropriate control panel option is ordered.
