I may be asked to install a fire alarm in a (Scottish) flat before it is rented. As I understand it, they need to be mains powered and linked so all sound if one goes off.
What is the easiest way to do this in a flat with high ceilings and extensive decorative cornice around the edge of the ceiling.
I do not know if there is a live in the ceiling roses, or only a switched live, and I will not be able to find out until I arrive (I live 400 miles away).
Any words of wisdom gratefully received.
