ENERLITES Low Voltage Ceiling Sensor Pir Occupancy Motion Detector, 360° Field of View, 1200 Sq Ft Coverage, Commercial/Industrial Grade, MPC-50L, White

Great Ceiling mount motion sensor, this is my second of this item, but it doesn't feet inside standard round plastic cutting box, I had to place box extender, other than this it is perfect.

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.

I'm very pleased with this unit. It's exactly what I needed for a basement hallway. It senses great, actuates predictably (most of the time) and was almost no trouble installing. The only issues I have with it are as follows: 1. The PIR lens doesn't like to stay in place. It's very easy to inadvertently make it fall off. 2. The relay that actuates the light is pretty loud when it actuates. If my ceiling were taller perhaps the sound wouldn't be so loud but I would think there would be some way to attenuate the loud "click" it makes, even just a little. 3. We had this very strange occurrence where the power was shut off to the motion sensor so the space could be painted and then it wouldn't turn back on. It really threw our electrician for a loop. It worked perfectly well prior to painting. They masked it off and flipped the power switch to the lights (thus cutting power to the motion sensor) and then when they were done painting, they flipped the wall switch back on and the motion sensor wouldn't register any motion detected. It acted like it had no power. We ordered a second unit after a few days to see if it was the unit or the wiring but before the replacement arrived it spontaneously started working again without anyone touching it or any part of the circuit. In total it acted dead for about a week or so before it started working again. Very strange. Other than those issues, one of which I'm scared to try to reproduce, the unit works very well and I'm pleased with it.

It's 2025. Used in the garage as an entry light when the door opens. Still works great. Adjustability is very good.

I installed the line-voltage version to control a pair of light fixtures in the garage. It is working well with good range and sensitivity. I tried one of the $15 products that didn’t work and ended up replacing it with this one. Just be aware that the case is a bit of an odd shape and it extends into the fixture box. The plastic circular box I used didn’t work since it had solid ears that prevented the sensor from seating. I had to get a square fixture box so it would mount flush. Other than that minor issue, it suits the garage light application well.

The only light switch for my garage lighting was in the house, an awkward setup with only 2 lamp holders in the garage. I installed this in one of the two electrical ceiling boxes and changed the other to a duplex outlet in conjunction with installing LED shop lighting. With this ceiling occupancy sensor I can open the door to the garage and the lights will be on before I can even step into the garage. As another reviewer said there is a delay before it turns the lights on, this sometimes happens after a month or so but is fixed after the power goes off and on again (restarting the device) so I left the original light switch in place in the "on" position to facilitate restarting the device. I adjusted the duration so that when activated the lights will stay on for about 6 minutes which is perfect for my application.

This was perfect for what I was looking , same size easy to instal

Had this installed in our walk in closet and so far it works perfectly. It is very convenient to have a sensor like this installed especially for when your hands are full.

Had my electrician installed for me. Works well.

Les réglages et la sensibilité à la détection me conviennent parfaitement
