Review carbon monoxide alarm replacement
Check the installation or manufacture date. This is a 7-year planning reminder, not a guarantee of service life.
Why it matters
Planning ahead avoids relying on equipment beyond its expected service period.
Steps
- Check the installation or manufacture date. This is a 7-year planning reminder, not a guarantee of service life.
- CO alarms vary by model, commonly seven to ten years. Follow the marked replace-by date and end-of-life warning; use seven years until confirmed.
- Arrange appropriate replacement and record completion only after it is done. If you are only reviewing options, snooze or adjust the reminder instead.
How often should I review carbon monoxide alarm replacement?
