FIELD: alarm systems. ^ SUBSTANCE: invention pertains to a temperature sensitive detection cable in form of a line, which contains two adjacent detecting conductors. An NTC stopping layer and a meltable insulating layer are put between the detecting conductors. The cable is characterised by that, a broken conducting layer is put between the NTC stopping layer and the meltable insulating layer along the fire detection cable. At least one of the detecting conductors is elastic. ^ EFFECT: overcoming disadvantages, related to inaccurate temperature alarm, arising from insufficient conductivity of the two detecting conductors, when a temperature sensitive sensor in form of an analogue line with a meltable insulation layer is heated. ^ 15 cl, 10 dwg |
