How do I keep them working?
There are two simple steps to remember when caring for your smoke alarms.
  1. Replace the battery at least once a year in models that use 9 volt batteries. The Seattle Fire Department recommends you change the battery in your smoke alarm when you change you clocks each fall.
  2. Keep them clean. Dust and debris can interfere with how smoke alarms work. Regularly vacuum over your smoke alarm to keep it working right.
What’s Chirping?
The “chirping” noise lets you know that the battery in your smoke alarm needs to be replaced.
