Unscrew the back plate from the ceiling or dry lining
box. Save the screws for installing the new back
plate later. You’ll see one or two cables coming from

damaging your ceiling or wall. There will be two or
four wires aached to the old back plate. Disconnect
them all.
Tip: Your old smoke alarm might make a loud noise
when you disconnect it.
