Work in progress

In Scotland, there's a new law coming in that says we must have interlinked fire alarms by February 2022. Interlinked means if one goes off, they all go off, so you will always hear an alarm wherever you are in your home. These ones interlink wirelessly, and I've tested them ready to put them into position.  I'm hoping the the 3M sticky mounts will stick them well enough to that I don't have to drill holes in the ceilings.
