Fire-watching device in a building.

The arrangement for fire control in a building comprising at least one passage for at least one line (2), in particular an electrical cable through a wall opening in a building of the walls (1). The implementation forms with two wall opening on both sides of the wall to the line (2) on the one hand and the soffit (3) of the wall opening on the other hand final sealing bodies (4) a fire protection barrier through which the pipeline route between the two through the building wall (1) separated from each fire zone areas is sealed off fire resistant. Within the implementation of at least one electrical temperature sensor (12.1 to 12.4) is arranged, the electrical connection line (13) serving as one of the detection of the sensor signals monitoring point directly from the interior of the passageway into the building wall (1) is performed and therein passes flame retardant. The sensors and their connecting leads (13) are therefore protected in case of fire from premature damage. The implementation with the sensors and the connecting lines (13) is embedded in the building wall (1) already during their manufacture.
