Wiring HELP for 2 switches, 1 light, 1 fan & smoke detector!

Hey all!

I'm trying to find the best way to wire a dual switch for a porch light and indoor ceiling fan. The source power cable, fan power cable, porch light power cable, as well as a smoke detector power cable all reside within an accessible metal j-box (see attached drawing).

I currently have a 12-2-2 (black, red, white, white, ground) cable run from this j-box to connect to a single pole dual switch.

Can anyone give direction on what should happen in the j-box? I don't want to get any wires crossed and my brain is having a hard time figuring this one out!

Currently, my plan is to take:
  • the 12-2-2 feeds (black and red) from the switch run and tie them into the hot (black) from power source.
  • a 12-2-2 neutral (white) from switch #1 and tie directly to the hot (black) from the porch light
  • a 12-2-2 neutral (white) from switch #2 and tie directly to the hot (black) from the fan
  • the hot (black) from smoke alarm to hot (black) from power source
  • the neutrals from power source, fan, porch light, and smoke detector all together

Any thoughts?

Welcome to the forums.

Your wiring idea will work.
The white wires are white wires...... not neutrals. You should tape those a different color so that in the future they aren't thought to be neutrals. I would tape one black and one red. This way you will know your switched pairs.

I see joed has a diagram up. I'll see yours and raise you one. Originally I had thought to just use three wires as I've shown and cap off the extra white wire. This diagram just represents the hot wires. All the neutrals are understood to be connected.

You should use the white to bring power TO the switch?
