D1 Ceiling Occupancy Motion Sensor, High Bay Fixture Mount

In summary: Good product, pretty good instructions, and very good price. I attached this to a small metal Junction box with 1/2 inch knock-outs, and mounted it to the ceiling of my garage. Then added the plug end of a heavy duty extension cord to bring power to the box, and installed a duplex outlet for plugging in two shop lights. The outlets turn on whenever there is motion below, and stay on for 5 minutes (the minimum setting) after I leave. When working at by bench, with my back to the sensor, it usually picks up my arm motion and stays on for as long as I am in the area. Only once in three months has it turned off while I was working, and that was resolved by simply turning around - which triggered the lights back on. My device triggers on most any motion that lies within a 45 degree cone from the ceiling. Note that Time knob only has a few different values. It is Not infinitely adjustable. However my unit was settable down to 5 minutes, which is perfect for my use. Note also that the Instructions do not say how to adjust the "Light"knob. If you know exactly what it does, put it in a review so future customers will know.

REALLY EASY TO INSTALL WORKS GREAT ON HIGHBAY LIGHTS ALSO WE HAVE BOUGHT OVER 100 OF THEM ALREADY ITS OUR TOP SELLER

I bought this unit to replace the pull on/off switch. Looking at the wires of the units, I was just gonna match wiring. I thought I should check the instruction just in case. Everything seems normal, and there was a wiring diagram. It seems odd the way it was drawn. It shows the black wires (from power, detector, and to light) connected together on one side, and the white wires (from power, detector, and to light) connected together. Because the detector has a red wire (3rd wire), it's connected to the white wire that leads to the light. So, I joined the red wire with the white wires in one twist cap. Then I plug the cord to the outlet, and there was noise as if the light bulb burned. I removed the detector unit, plugged in the light, and no light. I searched the problem with no success. Then I realized it might've been the breaker. I checked and it was tripped. So, following the diagram, I short-circuited the breaker switch. Went back to my original thinking of matching the wires and using the little knowledge of wiring, I wired the black wire from the power to the black wire of the detector, the RED WIRE OF THE DETECTOR TO THE BLACK WIRE OF THE LIGHT, and all the white wires in twist cap. Plugged in, and the light turned on. After some seconds passed, light turned off. I moved to the detection area, and light turned on. I wonder if the company ever test its own instruction and diagram.

I always like to read "other buyers reviews" and look over a PDF install instructions when provided. This really poor wiring instruction diagram stood out as confusing. Thanks for other buyer's reviews that made it simple. Disconnect the the black wire from "power source" and wire direct to black wire from "sensor". The " red sensor wire" is then connected it to the other black wire just disconnected coming "out of light fixture". Wiring the "white sensor wire to white neutral bundle or white wire' coming from the power source receptacle to complete the wiring job. It should be mentioned not all 3 way switch traveler wires coming into the power sources receptacle box are the same color so hopefully your electrician wired a "black pigtail" to hot source to eliminate confusion when the connecting a light or other device. I spent a few hours researching the best way to handle my wife's requested for an auto on auto off light upgrade. In my case a wall switch motion sensor was out the question and this motion sensor sure made the project extremely simple. Fifteen minutes to install on my overhead florescence light. My motion sensor works just fine and I would recommend it to others.

The produce was installed in an overhead kitchen light with two 4' LED tubes. It performs well, and the sensitivity worked great to ignore the cats while picking up the dogs and people. The big complaint is: It has an analog time dial, which SHOULD allow you to gradually increase the on time from the default 15 seconds on up to whatever you want. In reality, it goes from 15 seconds directly to 5 minutes with no middle ground. 15 seconds is ok *IF* you are moving around, but if you pause to fill a pitcher at the sink without waving your arms, the light shuts off. If you set it at 5 minutes, it tends to see a dog or something, and never shut off. I really needed it to stay on for 45 second to 1 minute. I am just leaving it at 15 seconds and waving a lot.

We are an electrical contractor and purchased 31 of these for a job. Over the last 3 months the client has called multiple times to report occ sensor failure. I have had to replace over half of these already with higher quality occ sensors. Customer now requires that I replace them all. Costly lesson. DO NOT BUY THESE. THEY ARE GARBAGE.

This product worked great for me. I put it in the entrance to two closets and it turns on all the lights. The sensitivity is adjustable, and for me the ability to set the delay all the way to 30 minutes was great since the back closet is not visible from the device. I wanted to mount it on my ceiling and the electrical outlet comes out horizontally, so I had to get a 90 degree elbow pipe to have the wiring go up into the ceiling.

Love this device. With a house full of people who can NOT trun of the lights and an electric bill that is through the roof, this was the answer. I attached this to many rooms that people walk through with hands full like our pantry. It turns the light on and then shuts if off again at a predetermined time of no motion.
