FIELD: fire protection.
SUBSTANCE: invention relates to the field of fire extinguishing, namely to a fire extinguishing device (FED) with a module (1) placed inside with an aerosol-forming or gas-forming composition, which can be used for operational extinguishing of electrical panels or cabinets when exposed to high temperatures, for example, during a fire. The fire extinguishing device contains an FED housing, while the module (1) protrudes beyond the FED housing and contains a self-igniting thermal igniter (22) having an initiation temperature lower than the initiation temperature of the module (1), while additionally containing an actuation sensor (11) and a manual start button (18) of the electric igniter of the module (7), a contact group (10) for initiation through the conductors by an external signal of the electric igniter of the module (7) or the supply of an initiation voltage to the manual start button (18) and the electric igniter of the module (7).
EFFECT: increase in the efficiency of primary fire extinguishing with an increase in the effectiveness of preventing the spread of fire in a confined space, in particular, such as an electrical panel while simultaneously issuing an information signal to emergency control panels.
