FIELD: fire extinguishing.
SUBSTANCE: autonomous fire extinguishing device (AFED) with an aerosol-forming or gas-forming composition placed inside, AFED consists of a housing (1) and a module of an aerosol-forming or gas-forming composition (2), an initiation unit, which is made in the form of a thermochemical igniter (15), containing a temperature-sensitive element (16) and an electric igniter of an aerosol-forming or gas-forming composition (6), made with the possibility of initiation by an external signal, and also additionally contains at least one thermal fuse (3) installed in the power wire (11), moreover one of the contacts of said thermal fuse (3) is connected to an initiating temperature-sensitive device (7), which is connected to an electric igniter of an aerosol-forming or gas-forming composition (6).
EFFECT: providing the possibility of using an autonomous fire extinguishing device for electrical sockets, socket boxes, electronic equipment elements, digital modules and printed circuit boards, electronic and electrical devices, as well as the possibility of initialization with a thermochemical igniter, an external electrical signal or initiation from an internal or external initiating temperature-sensitive device, and also capable of generating an information signal for the operation of the device.
