    False alarms


    Was already installed in our house when we bought it.


    Problems started about one year after moving into our new house (probably when the original batteries started to run low). Our first one of these alarms started going off at random, when there was no cooking or anything going on, so had to take it down. Perhaps summer humidity set it off. Then some weeks later, the second one (in a bedroom) started false alarming constantly. New battery made no difference in either case.

    Do not buy these, they're obviously cheap for a reason.

    Recommend it?

    No, this product has too many drawbacks.

    Low price.


    False alarms. I bought three, and they have all given false gone off at random times. Changed batteries on all, but one still went off at random. So I bought a replacement with a different brand (FireGuard FG127). On opening the packet, it's got the same form as a CodeRed. And a very similar sticker on the back of the unit under the mounting cover. So CodeRed is the same as FireGuard, except the front has a slightly different moulding.
