I'm putting a couple smoke alarms up in a house with 11' vaulted ceilings- for 8' ceilings, I'd place them either on the ceiling or very close to it on the wall, but I know the batteries would never get checked if I did that here. Placing them at a height where they can be checked with a chair or small stepstool places them about 9' off the ground, and 18-24" shy of the peak of the vaulted cieling. Is this acceptacle practice? It's 3/12 slope of the cieling, btw.
