Fire and Rescue NSW are reminding people to check smoke alarms, wherever they're sleeping.
According to Fire and Rescue NSW, 56 per cent of fatal house fires between 2000 and 2014 had no smoke alarms present.
The majority of these deadly fires also occurred between midnight and 6am when people were asleep.
"If you are in a motel, hotel or caravan park and you notice there isn't a working smoke alarm you need to report it to management," Narromine station commander, captain Ewen Jones said.
"It is illegal not to have a working smoke alarm in any area where you sleep."
NSW legislation stipulates that residents must have at least one working smoke alarm installed on each level of their home. This includes owner- occupied, rental properties, relocatable homes or any other residential building where people sleep.
The alarms detect smoke well before the sleeping occupant.
