“Replace 60 months” on First Alert smoke detector, but no beep?

I have a First Alert SCO7 smoke/carbon monoxide detector, built in June 2011. It tests just fine. On the back, it says that it will give a specific warning beep when it reaches the end of its life, yet “replace unit after 60 months” is printed next to it. Aren’t these units supposed to last 7-10 years? Why would it say this?
