How long will my smoke alarm last?
Most alarms installed today have a life span of about 8 to 10 years. After this time, the entire unit should be replaced. It is a good idea to write the date of purchase with a marker on the inside of your alarm so you will know when to replace it. Some of the newer alarms already have the purchase date written inside. In any event, always follow the manufacturer’s instructions for replacement.
