What would happen if you hooked up two motion sensors in parallel with a flood light? I have a customer that wants a set of lights to go off from differant locations outside his house

It would work. I've wired setups where a motion sensor and X-10 module have been in parallel and it works just fine.

what you guys think

I have two of 180w flood light on (dawn to dusk) sensor, planning to install receptacle for Malibu Transformer on the sensor load side. Sensor rated for 1800w got it from HD. Load on transformer is 300w low volt light. Now the question is .will this work and what problem might i encounter beside the dawn to dusk issue.
Thank you

I have done this for a long driveway. Basically I fed the first sensor then I ran a 3 wire cable from the first sensor out to the lights and continued the 3 wire cable to the second sensor. The neutral fed thru to the other sensor and caught the lights as well. The red was the return from both senors to the lights and the black fed both sensors.

The truth table for the logical OR function is:
Output is TRUE for any one or more TRUE inputs.
For the AND function:
Output is TRUE only if all inputs are TRUE.
For the the EXCLUSIVE OR function which only can be a two input circuit:
Output is TRUE if either one of the two inputs is TRUE but not both.
The NOT function is a single input and single output circuit:
Output is TRUE if the input is FALSE and vice versa.
If you assign the value of TRUE to a closed contact, then contacts (single pole switches) in parallel are a logical OR circuit. So long as any one or more switches are closed the output is energized.
Put the contacts in series and the result is an AND circuit and all contacts must be closed to produce an output.

Either motion sensor will turn the light on. GAR good post I must admit I didn't think in those terms although I guess I actually did without realizing it.
