Detectomat SKR Alarmline II Red PVC Sensor Cable

It is the red PVC jacketed sensor cable of the Alarmline II system and consists of four conductors. Two conductors with transparent jackets carry copper conductors coated with a special polymer whose resistance varies with temperature; the white conductor forms the calibration resistance, while the red conductor monitors the average ambient temperature. A foil screen and protective outer layer are drawn over the twisted conductors. This makes the cable responsive to temperature changes at every point along its route.
