FIELD: equipment for fire extinguishing, in particular, powder-type self-starting fire extinguishers, or operated by external signal to fire extinguishers. SUBSTANCE: powder-type module has body accommodating powder and gas-generating substance. The latter together with fire-extinguishing powder occupy the volume amounting to not more than 99% of the body total volume. Body has container accommodating gas-generating substance and initiating device connected with signalling system for forced initiation of gas-generating substance upon reception of electric pulse, or made self-initiating by the effect of heat flux of fire seat. Body has opening in wall for container whose side walls has holes for discharge of gases to space of body. Body walls are made with sections of weakened cross-section or weakened material for guaranteed opening of body in case of rising the gas pressure in body space of module and throwing the fire-extinguishing powder. EFFECT: provision of local and/or volume massive one-time discharge of fire-extinguishing powder to zone of fire seat. 34 cl, 11 dwg
