Clocks Fall Back an Hour this Weekend
When alarms don't work, it's usually because of dead or missing batteries.
Smoke alarm batteries need to be tested or replaced once a year, but the alarm itself only needs replacing every ten years.
Firefighters carry extra smoke detectors when they go out on calls just in case they notice one that needs replacing.
The Columbia Fire department did say if you can't afford one, it would be happy to provide one.
