Most RF lighting systems work like this:

You connect the load to the dimmer, the dimmer can receive a signal to tell it to turn on off dim etc. It can also send its signal back to report its status.

After you replace the dimmers or switches with the RF ones, then you install a keypad in the wall instead of the old LV thing. Most keypads need either a LV power supply or line level direct to them. When you press a button on the keypad it (depending on the system) it sends a signal to a dimmer telling it to perform that action.

The only wiring difference is that most of them use a dimmer or switch on the load, then for 3 or 4 way switching you install "keypads" that look identical to the switch/dimmer. The keypad wirelessly tells the dimmer/switch the necessary command. Functionally it works exactly like a standard 3/4 way switch but you do not need travler wires going between all of the 3/4 way switches, they now only need constant power to broadcast the command to the dimmer/switch controlling the load.

Make sense?
I see. I guess I thought there would be some magic to it. If I've got to tie into the load, then I could just as easily run a normal switch. However, if it were for a 3-way, then this would be the better choice.

Thanks again for your help.

Personally I would tie into the load anyway, I was trying to figure out a way to add back in the lighting control w/o additional wires. If you want to keep the LV system I'd have to see the wiring to figure out if it could be done with an RF based system with dry contact closures.

I don't know what it is but it goes to twelve



Just because it's within code doesn't make it safe.

Just because it's against code doesn't make it unsafe.
