Hello,

I presently have two mains interlinked smoke alarms with battery back
up. Unfortunately one is faulty and keeps sounding. I have tried
cleaning it with a hoover but no luck. I am interested in whether all
mains interlinked smoke alarms with batteries are the same.
Basically, if I bought another two interlinked alarms that were a
different make could I simply replace the current two by copying the
connections?

Alas no... it might work but there is no guarantee. Stick to the same
brand as already fitted.
