There are 2 BRK wired smoke alarms in our house which came with the house as a new build. Though 26 yrs old they still work. (toaster on with kitchen door open!) I was thinking of changing them to something more modern. On you tube there are videos on how to do this. There is one with a kidde alarm that came with some wiring adapters, but most of the videos are american in origin. I asked Kidde about this one with adapters but they didn't know what I was on about. There are adapters on Ebay but all seem to be from America with high postage costs. Would these fit here knowing their voltage in homes is different to ours. Are there any adapters available in this country that would make the job of swapping any easier?
