Cheers. The issue I have is that I don't want all alarms to be hard wired, the cost and disruption would be too much, but I believe that those that are on the landings have to be hard wired for the regs so I need the two to speak to each other.
This one is £35 from tool station. Specifies that it does exactly what you want, wifi's the alarm from hardwired and the other way. Searching for linked fire alarm network might throw up some more possibilities.
Cheers, I hadn't looked on Toolstation. Although I really need a definitive answer from building control on how many smoke alarms I need, 8 seems excessive for a 3 bed flat but details on what you need if you don't have fire doors is scarce.
