Firs,t you need to check the regulations for your area. These directly exchange for for the older models if you have them (screw into existing baseplate) but would also not be too difficult to fit as new items - again, though, check if you can do this or whether you need a registered electrician,

We recently had a 2 storey extension done and got the building regulation for approval. When the inspector arrived we were told we need to replace the existing battery operated smoke detector with the mains on both levels. With so many available in the market anything from £9 to even £300 depending on your pocket. So I read the reviews here and stumble upon the Firex Kidde Mains Powered Optical Smoke Alarm . The building reg inspector suggested the optical one's as opposed to the other ones available. Package Contents - 1x Mains operated smoke alarm 1x Installation manual 1x battery Set of screw fixings It comes with 3 wires attached to it , one being a interconnect. If the smoke alarm goes off the seconds one immediately kicks in at the same time. The inspector did the test and was very pleased with the installation. If you know how to install it, then ts very simple to do so. I am not familiar with the electrics so had to get a professional to install 2x smoke alarms for £80. We got 2 quotes for £200 for the installation. You can do a test by pressing the tiny button. The GREEN Led on the smoke alarm looks great too, not too bright or low either. Overall a great product and does a great job. I would highly recommend the product. I really hope you found my review helpful and would love for you to click on the “YES” button to say so. If you don't think my review has been helpful, before you click on the “NO“ button to say I was unhelpful, I would love you to leave me a comment with your thoughts, so I can try improving my future reviews

Well, I'd like to say it works perfectly. But I don't want it to go off unless theirs a fire haha. But seems absolutely fine. 😊 thanks

The cons first- out of the four ordered two had low battery power and I suspect the other two to be the same so I will swap out those batteries for new ... Pros - easy to install on to old firex ones so easy I let my 17 year old daughter do them all with no issues (apart from batteries) Hopefully that's them now for the next ten years
