Questions & Answers

howSA303 to put the battery in

Asked by: Eloy
I had the same question as I couldn't get the test beep to work, and found a YouTube video on it. When you open the battery door, the + sign goes on the left, and you will be able to close the battery drawer. If you put it in backwards, it will not close, so just flip it around. To test the device, you have to hold the test button a few seconds. If it beeps you're good to go!

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.

When I first installed these (I bought 3) straight out of the package, one of them made its piercing alarm sound a couple of times in the middle of the night (not a good way to wake up). I took them all down about a week after the initial install and vacuumed them out. Since the vacuum, they have been quiet for about a month. They are inexpensive and come with a good-quality 9Vdc battery.

So, I called and ordered over the phone. The call went well, and I received my product in a timely manner. The product itself, shows a red light which concerns me that the instructions were not clear enough.

I was cooking something in the kitchen and didn't actually see any smoke coming from the pan--but the First Alert smoke alarm did and started beeping. I like knowing that it is so sensitive.
