Re: [DIY] For super-electricians.

 

See ... this is news to me.  3-way motion detectors.  Thanks. 

I also found a way to hook up regular motion detectors - you still have to run three wires from one detector to the other: hot powers both switches, neutral to eventually go to the light and the switched power from both detectors (it shows blue in the diagram) is spliced to the power to the light.  I can see that the current will be halved in each output when both are on but at the splice to the light will resume the normal current.

Gee thanks!  Thats what makes you guys super electricians!

All u have to do is replace the three way switches that are there with Motion detector three. Way switches.  It's not rocket science.  Let's not make a simple thing complicated.

Its impossible to double the volts in single phase service.

Does sound simple, but what happens when one switch is on, which means the red wire of both are energized, then the other switch is turned on at the same time?  Seems to me you have just doubled the volts on the wires leading to the light.

Yes!  Did this on my bridge lights.  I have sensors on each side so no mater witch direction you approach the bridge it lights up.

They are in essence just automated switches so you should be able to replace the switches with the sensors.  The sensors have three wires as do the manual switches.  Just wire them the same red to red, white to white and black to black.

We just started a managing another building.  There are stairs that had a 3-way on top and bottom.  The new owner says he wants a movement sensor in both places, instead.  I am not familiar with a way that an arrangement like that can happen.   Does anyone know of a way to do this?
