The San Luis Obispo City Fire Department is urging the community to make sure they are maintaining their smoke alarms during the holiday and winter season.
Batteries should be changed every six months and they also recommend you test your alarm once a month to make sure it's properly functioning.
James Blattler, a San Luis Obispo City Fire Department spokesperson, said most people are unaware that smoke alarms expire after 10 years.
“When you are changing your batteries every six months, take it off and if you look on the back, you can see that the manufacturer date will show when it was made,” said Blattler.
A smoke alarm at a local hardware store can cost anywhere from $25 to $60.
