You should install a smoke detector inside each bedroom, and on every level of your home, including the basement.
Smoke alarms should be installed at least 10 feet from a cooking appliance to minimize false alarms when cooking.
Don’t install them near windows, doors, or ducts, where drafts may interfere with their operation.
Use interconnected smoke alarms. When one alarm goes off, they all go off.
Test smoke alarms at least once a month using the test button. Make sure that everyone in the house knows how to respond.
