Smoke alarms - out of sight and out of mind until the battery goes bad. The only time most people think about them are when you are trying to figure out which alarm is chirping incessantly.
Do you have the right number in your house and in the correct locations? Smoke alarms are required on every floor of a home, outside each separate sleeping area and inside every bedroom. Interconnected alarms are the best - they can alert you to a problem in a different part of the home.
Batteries in smoke alarms need to be replaced yearly. Smoke alarms should be tested monthly to ensure proper operation. Smoke alarms have a useful life of about 10 years before they need replacement. This may seem like a daunting task but most are designed to be easy swapped out. Look for a post in the next few weeks about inspecting and replacing a common type of smoke alarm in houses built in the early 2000's.
