THE Country Fire Authority is reminding people to change their smoke alarm batteries when daylight saving ends tomorrow.
Clocks go back one hour on Sunday morning.
Bendigo Country Fire Authority senior station officer Tim Fitzgerald said smoke alarms saved lives.
"They alert the occupants of a house that there is something amiss, whether there is smoke or a fire, or something has gone astray," he said.
"It is an early warning device for people."
Mr Fitzgerald said people should check their smoke alarms are in a good-working condition.
"You change the batteries, close the lid and push the button to make sure it works," he said.
"If it beeps then you know it works."
