Question about Electrical Supplies
I need the ability to wire a security motion detection light between two 3-Way light switches (already installed - wired currently as single pole single throw - why I dont know). I would like the result to be that each light switch has the ability to turn on the light full, or has the the ability to turn on the light switch to motion detection. Alternatively if this isnt possible my motion light is the type that when you flip the light switch shortly it will turn on for a period of time and then turn off. Alternatively the switches would be to turn the motion detection on and off from each light switch without having to go to each light switch to turn it on. The way the contractor wired it was that if the 3Way switch was flipped in one place - it had to be flipped back in that same switch and the other switch waa not useful except on/off with the other switch being in an exact state. Please help. Specific models of lights that help with this problem and links too them would be highly useful and specific diagrams for wiring would be highly useful. The contractor and home builder (who will be nameless for now can't seem to get this right after a year of trying.) Heartspeace
One of the switches needs to be a 4-way then the PIR will act as any other switch. The downfall is if the lights are on and motion is sensed they will turn off.
My preference is to connect the contacts of the security device across the travelers of the three way circuit. The travelers are probably the red and black in the three conductor cable. When motion is detected the lights will turn on regardless of the settings of the three way switches then after timeout they will turn off. If they are turned on with one of the three way switches nothing will happen when the motion detector turns on except you cannot turn the lights off until the security device has turned off.
I hope this helps. The motion contacts need to be isolated from the motion detector power.

well lets see on one side you should have two brass screws that would be to interupt your lead to the fixture then you either have a brass and silver screws on the other side or you have black and white wires the black or brass is always hot the silver or white is neutral does that answer your question if not hit me back with a description of what your switch looks like

I opened the box and traced the lines to see which are connected
when the switch is turned on and I left the red wire disconnected.

SOURCE: I installed the motion sensor
A quick peek inside a sample Leviton manual confirms that your wires are connect correct - BUT...
The remaining 3-way switch needs a jumper wire.
See if your instruction manual shows the same thing as image below.
Let's go through this.
The yellow wire connects to a traveler ... and that traveler connects to one of the brass screws on 3-way switch.
The black wire from Motion sensor also connects to a traveler wire ... BUT you have to identify which traveler wire and which brass screw that traveler wire connects to. And then, put a jumper wire (a short piece of wire) from that brass screw to the dark-colored screw.
I think that will do it.
Add a comment if your device is different.
Some of these electronic devices are reversed when two of their wires are connected together.
That's what the jumper wire is doing. So the 3-way switch is just connecting and disconnecting the black and yellow wires, and that action reverses the circuit in the motion device.

Here is a page of diagrams: http://www.do-it-yourself-help.com/3_way_switch_wiring.html
You have to use a 3 way switch on both sides. You should be able to get a motion light that has an always on feature. To activate the feature then you need to turn the light on off on fast and then it stays on. Ceck with home depot or someplace like that for lights with that feature. IF not then you are going to need to run another circuit.
