I have about 15 BRK SC9120B ceiling smoke detectors around my house. They are a huge problem. ...

I have about 15 BRK SC9120B ceiling smoke detectors around my house. They are a huge problem. Every one has failed in the past 5 years and it is a continuous problem in the night when they chirp. I replaced them all after 5 years but still a problem. I would like replace them all with a simple/reliable "battery only" smoke detectors. QUESTION: Will the SA303CN3 battery only detector fit onto the "existing ceiling base" of the SC9120B detector?
Asked by: Chirp
I don't think so you may have to buy one and try it to see if it fit or call there 1 800 number and ask them if it fit.

how do I put the battery in

Asked by: Mich
The door connection is to the right of the First Alert on the alarm. The alarm needs to be twisted slightly to release the clasp.

Rated 4 out of 5 by from Good product for the price We have had this detector for over a year and we haven't had a single problem. Only once did it go off while cooking and that was while we were using the broiler. All in all for an inexpensive detector it does the trick for us.

Rated 1 out of 5 by from You get what you pay for I just ordered new smoke detectors to replace these. These things are annoying. They go off every time we cook even when nothing is getting burned. They chirp all the time even when the battery is still good. Basically they are garbage.

Rated 5 out of 5 by from Reliable and long battery life I've had this smoke detector (or maybe it's a very, very similar model from the same manufacturer) for about 15 years now. It did go off once when I burned dinner pretty badly on the stove, but apart from that, no false alarms. It goes through a set of batteries about once every 5 years, which is shocking to me, but it's saved me lots of money over the years. Would definitely buy again if I ever need to. At this point, though, I'd expect it to last me at least another 10 years.
