3 First Alert / BRK talking SC7010B smoke/CO alarms at my sisters I put in in 2007 have malfunctioned

That's 6 years and dead. They rapid beep 3 times and won't work. The instructions say replace when this happens. They have 5 year limited warranty.

Anyone else experience this?

AFAIK all detectors have a 'service life' & yours are at that point.

Personally I replaced all in my home at 3 1/2 to 4 years

I did a service call the other day to a home built in the 80's with the old Firex smoke detectors and they were still working properly...although I realize they need to be updated and replaced to current standards.

I guess it will give me more service calls.
