Wiring 2 Motion Detectors to the same series of lights?
I have lights that are built in to the risers of my deck stairs, 5 lights in all. Since it’s quite dark in this area, I’d like to install a Motion Detector switch at both the top and the bottom of the stairs, so that no matter where you start from, the stairs will be completely lighted as you go up or down. Basically, the lights would be wired between the 2 switches.
Is there any problem with wiring 2 motion detectors like this? I assume I would need to wire it sort of like a 3-way switch. The motion detector I’m looking at has red, black and white wires, so could the red act as the traveller wire connecting the two switches, as well as connecting to the light load? (The manufacturer does not have specific information on this type of setup, but on the other hand does not prohibit it either.)
Advice is appreciated!
You can wire the lights using 2 motion detectors but not like 3 way travelers. You need to run a new 14/3 wire from where power comes from house to the first light to each motion detector. Tie black from house power to blacks from both detectors and the reds back to load (lights). Wire motion detectors color to color. If you had switches at top and bottom of stairs, they make 3 way motion detector switches but they probably wouldn’t last long outside. Also, motion detectors are rated if memory serves at 300 watts so total wattage of the 5 lights doesn’t need to exceed this.
