NSW Fire and Rescue: It is time to change fire alarms over

NSW Fire and Rescue are calling on residents in Grenfell to check their fire alarms and change batteries on their devices coming into the colder months of the year.

According to NSW Fire and Rescue it's been a decade since NSW mandatory smoke alarm legislation was passed, which means millions of smoke alarms across NSW are now reaching their 'best before' date and are due to be replaced.
