Ceiling Fire, Springbank Rd, Panorama SA.

Old Electrical Wiring is HAZARDOUS!
FIRE often KILLS people while they SLEEP WITHOUT BURNING-
SMOKE contains poisonous GASES that sink to the floor and beds are usually close to the floor.
Standard home Smoke Detectors are designed for fires INSIDE the house's LIVING areas, NOT ABOVE the ceiling.
EXAMPLE (this video).
Tragedy was narrowly averted around 11 pm, 30th June 2016 after the parents of a young family had just settled down for a long winter's nap. They thought the vague smell of smoke came from neighbor's wood heaters as their smoke-detectors were silent.
The only clue anything had happened was their mobile phone, which was charging, squawked as their electric power went off: but neighbors' lights were still on!
Upon investigating the father detected smoke in the ceiling space an area not covered by the smoke detectors. The parents immediately evacuated the house with their three young children.
Emergency services arrived quickly and no significant damage was done. Several hours later the house was declared safe after all power was cut to the building.
Initial Inspection points toward electrical cable insulation becoming brittle over the years.
