Greetings,

If the company that makes the alarm tells you to replace it after five or
ten years they only have to charge you for that many years of liability in
the purchase price.

Hope this helps,
William

They say to replace your CO alarms every 5 or 10 years. Why? If they
still
test OK, why replace them?
