The invention relates to a glass-tube sensor for sprinkler systems, consisting of a glass tube, filled with liquid and held in a housing. Said glass tube can be destroyed by a control unit by means of an electric remote control element, thus releasing the extinguishing agent openings of the system. The aim of the invention is to develop a glass-tube sensor for sprinkler systems, which can be destroyed by an electric remote control element, that can be economically produced and maintained. In addition, the destruction of said glass tube should not present any danger and the propagation of the extinguishing agent after the destruction of the tube should not be hindered to a greater extent than is the case in conventional sprinkler housings. According to the invention, the electric remote control element is a heating element (2, 6, 7), which is fixed onto or in the glass tube (1). |
