I have a newish room (built in 2008, New York), and the smoke alarm had a wiring setup I am confused about. It has 3 black wires, 3 white wires, and 1 red wire. See attached picture.
Anyone know why there are so many wires? Shouldn't alarms just need 1 black/white? Not sure what the red was for.
I would refer to the original alarm in there, but the owner told me they don't remember how it was setup when they took it down.
Related, there are two wall switches in the room that don't seem to control anything - I am now suspicious that they go to this box, but no idea why you would want 2 wall switches going to the same box that has a smoke alarm?
