Very useful, Gray wires explained

My review is for the “Ceiling Sensor for J-Box Installation MPC-50V” the one that comes with 2 small grey wires for a momentary switch. I installed mine in my garage which is my work shop and it works flawlessly, it has an internal relay so it can work with any type of load up to its limit (800 watts Incandescent) The gray wires and the Vacancy function (dip switch) is pooooorly explained in the instructions. In most cases the grey wires are not used and the vacancy dip switch is left to disable but if you want to know what do they do here it goes: They should be connected to a momentary normally open switch (Push button like your door bell or your garage door opener) I set my sensor to 10 minutes delay (I call it timer) so lights will go off 10 minutes after the LAST motion is detected. VACANCY DISABLED: The sensor detects motion > lights turns on > new motion reset timer, timer runs out > lights turns off; while lights are on, the momentary switch will turn lights off and on as many times as you want until timer runs out. If you turn the lights off with the momentary switch they will remain off even if new motion is detected (timer ALWAYS resets w/ new motion regardless mode setting ) UNTIL the timer runs out, THEN a new motion will turn lights on. VACANCY ENABLED: The sensor is sensing but lights remain off, the momentary button will turn lights on, ONLY if timer is active that means sensing must happen before, if the lights are on and the timer expire the lights turns off BUT if in the next 30 seconds the sensor sense motion again the lights will tune back on for another timer period, if the timer and the 30 seconds expire you go back to the beginning were sensing will not turn on lights. In short this mode prevent lights from turning on during periods you don’t want, lights stays off if manually turned off or timer + 30 sec expires. In my case I have it on Vacancy Disable. I push the momentary switch if I know I will not return for a while so lights do not stay on for the duration of the timer.

UL and other approvals. Easy to install. Mounting screws match up with ceiling box

I returned another brand that was about 1/2 the price because the mounting holes were in the wrong place and had no approvals. . This brand/model is made correctly and has all the approvals.. The little cover pops off with just a fingernail on one clip (you do not use a screwdriver as it is too thick and will damage it). If you have to use a guitar pick or razor knife or butter knife). The cover just snaps right back on. The wires are labeled. Red goes to the load (light), white goes with all the other whites (neutrals) , black goes to the black hot. The other two little gray wires are for a momentary switch that most won't use so you tape each end up and then bundle them together with tape close to the unit to get them out of the way. You also have the switch on it set to not using the wires (you do all this before you begin to mount it). It screwed on a hex ceiling light box. Its only plastic so don't over-tighten. Use the screws already on the box as it does not come with any. It has a test mode. Then you set the timer on how long to leave the light on once it senses motion. It rechecks for motion and starts count down with motion. It also comes with a little sticker sheet to stick on pieces on the sensor to block detection from the sides you may not want it. I am happy with this unit.

Closet light

I purchased this light so that when I walk into our storage closet the light would go on for me automatically as most of the time Im going in I have my hands full and end up tripping on things trying to get to the light. I would recommend the light for this exact situation or any space that someone needs a light to go on for them. I found that the light was easy for me to install and did not require much knowledge of electricity to do so which was important.

Works where others didn't

I tried a cheaper brand of ceiling sensor, and the would not work in my garage or another small room with a window. They would keep the light on all the time from false triggers. This works perfectly without any errors so far. My only complain with this one, is you need to use a junction box above because it doesn't have a "finished" look if you were to just mount it to rafters.

Good quality and works as designed

I used this in my master closet. If you are not competent to do electrical work, hire an electrician. I am very skilled and did the work myself. Install was straight forward and the settings/ testing went fine. My wife is glad we bought it.

Great sensor, great value, looks great.

Easy to install, works without issues at all. You need the larger boxes for it, not your avaerste size junction box, but other than that I’ll be using these more in the future. They also look great on the ceiling.

Super Sensor

Very inexpensive, very well made, you must use a 4" octogan box. Other than that it works very well.

Works

Works pretty much as expected. Detection range seems to be about 10-12 feet, at least the way I have it set up.

Choo! Choo!

Come on and ride this occupancy sensor train and make that taint tingle ever so slightly. Oh yeah, works good other than the motion detection is hit or miss sometimes.

Super value

Out perform the "high end" models on every aspect. Easy to mount, easy to access, easy period n worked as it should!! Amazing product
