Hi all
like to talk about the new smoke alarms that are interconnected. I'm a X electrician that gave my job away after getting a major injury that stop me working till today.
We have in our house 5 HARD WIRED old ionisation sensor that have been there for at least 8 years so I'm thinking about replacing them with the new Photoelectric type smoke detectors. I have been looking for a few brands and have noticed some brands need to cut a large hole in you ceiling but I don't like that as to cut a hole up too 75 mm diameter hole in the plaster and in the future you need to replace them say in 8-10 years you are left with hole as no doubt the newer future detectors will need no hole or a very small hole to fit them.
As a example the CLIPSAL-755PFM4 has a ugly butt to hide so you need to cut the plaster to let it in the ceiling.



What do you think about the Wireless one like.



Any more info appreciated
