all right ill explain.
i went for my sim recurrency abt a month ago and one of the exercises we practice is and engine fire before V1 on the take off which involves a reject. on coming to a stop the ecam will be carried out and since the fire continues to burn the aircraft has to be evacuated. ( fire pb remains illuminated).
on the ecam it states to swith off all engine masters if the fire continues. since we do not use apu bleed for the take off (company SOP) it reverts to battery power.
whats happened in the sim was after completing the ecam and only on battery power the fire light was not illuminated. which techincally means the fire is out. how ever the evacuation was carried out as a precautionary measure.
in real life would the fire have been present or not is my question.
ie when your only on battery power. acft completely stopped. fire pushbutton pushed. bottles discharged and your engine is still on fire.
hope this info will be helpfull.
thanx.
