How to do it

Step by step

  1. Press and hold the test button on every alarm; replace any that stay silent.
  2. Check the date on the back. Anything over 10 years old gets replaced.
  3. Install one alarm inside each bedroom, one in the hallway outside, and one per level. Keep them 10 ft from the stove.
  4. Add combination smoke/CO alarms near sleeping areas if you have gas or an attached garage.
  5. Write the install date on each alarm with a marker.
When to call a pro: Hard-wired, interconnected alarms on a 120V circuit: hire a licensed electrician if the wiring is damaged.
