DAYLIGHT savings has started and NSW Fire and Rescue has issued it's biannual reminder for householders to check their smoke alarms.
Exelgard spokesman Matthew Pearson said people should also consider installing a carbon monoxide alarm.
Mr Pearson said there were important differences between photoelectric and ionisation alarms.
"An ionisation smoke alarm detects a fast flaming fire, and is recommended by fire authorities for its ability to quickly detect a fire, yet photoelectric smoke alarms, which detect slow smouldering electrical fires, are equally important," he said.
"Carbon monoxide alarms pick up the presence of poisonous and potentially fatal carbon monoxide gas."
"Check smoke alarm batteries and review each room in the home to ensure the right alarms are installed and located in the right locations," he said.
The Exelgard Carbon Monoxide Alarm is battery operated and looks similar to a smoke alarm but is designed to detect toxic carbon monoxide gas fumes. It is suited for use in bedrooms.
Photoelectric smoke alarms detect slow smouldering fires and dense smoke. They are suited for use in kitchens, hallways and bedrooms.
Ionisation smoke alarms respond quickly to fast flaming fires that produce very little visible smoke. They are suited for use in living rooms on each level of the home.
