Abstract

The present patent application relates to the field of electrical engineering and power engineering and can be used for the timely emergency shutdown of electrical equipment. The invention relates to a fire-extinguishing device having disposed therein a module (1) which contains an aerosol-forming or gas-forming composition, and comprising an electrical igniter (7) of said module (1) and a heat-sensitive trigger device (4), which are connected to one another in series by conductors, wherein the device further comprises: a contact group (10) for triggering, over conductors by means of an external signal, the electrical igniter (7) of the module, or for supplying a trigger voltage to the heat-sensitive trigger device (4) and the electrical igniter (7) of the module; an activation sensor (11), and a button (18) for manually activating the electrical igniter (7) of the module (1); the activation sensor (11) is connected by conductors (17) to the contact group (10); and the button (18) for manually activating the electrical igniter (7) of the module is connected by conductors to the electrical igniter (7) of the module. The technical result consists in increasing the timeliness of an initial fire-extinguishing action and more efficiently impeding the spread of fire in an enclosed space such as, in particular, an electrical enclosure, while simultaneously issuing a signal to trigger such fire-extinguishing devices, or issuing an information signal to emergency control panels.
