About Smoke Detectors


Smoke detectors save lives. And though these devices are small, relatively easy to install and inexpensive, their upkeep often gets altogether overlooked. Take a walk through your home to determine where your smoke alarms have been installed and if you need to install additional devices or replace any batteries. At minimum, functioning home fire alarms should be installed on each floor of your home, with additional units added near sleeping areas.

Ace Hardware carries a variety of smoke and fire alarms that work as separate units or wireless smoke alarms that communicate with each other to alert you from different areas in your home.
