FIELD: fire extinguishing.
SUBSTANCE: invention relates to the field of fire extinguishing, namely to an autonomous fire extinguishing device (AFED) with a node for mounting on a DIN rail, the device includes a housing inside which is placed a fire extinguishing aerosol generator (EAG) with an initiation node, a temperature-sensitive device (t1) and a sensor smoke (d2), while the EAG contains a housing with an aerosol-forming composition (AFC) placed in it, the initiation unit is made in the form of a thermal initiator and an electric initiator connected to it, connected in turn to an external voltage source, and a smoke sensor (d2) and a temperature-sensitive device (t1), connected to an external power supply by means of wires and a connecting block, are capable of initiating EAG through an electric igniter, while the smoke sensor (d2) is additionally configured to be connected via a control board. The invention can be used for prompt extinguishing of electrical panels or cabinets when exposed to high temperatures, for example, in case of fire.
EFFECT: increasing the efficiency of primary fire extinguishing with an increase in the efficiency of preventing the spread of fire in a confined space, in particular, such as an electrical panel, while issuing a signal to initiate the same fire extinguishing devices or an information signal to emergency control panels.
