The detection range of this alarm is 215–430 sq. ft (20–40 m²), so the number of alarms you will need is dependent on the size of your home. We recommend you prioritize the installation of alarms in bedrooms and hallways, and make sure you can hear the alarm from all sleeping areas. In a home with several bedrooms, install an alarm in every bedroom. If you are only going to install one smoke alarm in your home, install the alarm as close to all bedrooms as possible, and not in a basement or furnace room.

Like most items, smoke alarms wear out over time. Smoke alarms should be replaced at least once every 10 years. Any smoke alarm over 10 years old is unsafe and unreliable. Refer to your manufacturer instructions for specific recommendations.
