How To Install Multiple Motion Sensor Light

Question

Another much broader question was marked as a duplicate to this one, then I'll provide a general answer here. But first, the specific:

In your drawing, note how the supply neutral (lower) is separate from the internal "neutral" (upper). That'south a reddish flag: Probable it'south 12 volts DC. These preassembled lamps frequently use 12VDC internally since the LED heads require it, and 12VDC motion sensor modules are much cheaper than 120VAC ones. Then y'all'll have to test the lamp associates further to encounter if it'south adaptable.

Many lamp makers don't make sensors or fifty-fifty lamp heads. They kit together common off-the-shelf parts, commonly seen on Alibaba or eBay. If the sensor part doesn't work for you, and you tin can bypass the sensor and make it an "always on" light, in that location'due south good news. Yous may be able to supervene upon the sensor - many screw into fittings like this, and then proceed equally I describe beneath.

By and large:

I use divide detectors from lamps (they could be in the same assembly), and here'south how I wire them.

First, I utilise the type of sensor which has its own neutral (rather than the blazon which has no neutral and sits in a "switch loop".) This is very important. The sensor needs to be able to power itself independently (via hot and neutral) and does not intendance what is on the output. That means it won't interfere/clash with other sensors.

I run 4 wires down the length of all the sensor and lamp sites. The four wires are:

Light-green - Equipment Ground
White - Neutral
Blackness - "always hot"
Orange or Ruby-red - "switched hot"

I connect ground, neutral and always-hot dorsum to power supply at the service panel.

I attach each sensor to always-hot, neutral and switched-hot.

For a patently switch (pictured in position five), employ always-hot and switched-hot. It does non demand neutral, simply Code requires you bring neutral to the junction box.

Each lamp gets switched-hot and neutral. If the far end of the string is all lamps, you don't need an ever-hot.

Grounds everywhere grounds go.
