From the Manufacturer
Leviton's OSSMT multi-technology Decora brand style wall switch occupancy sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications, including: - retrofit- private and executive offices- conference rooms- storage areas- restrooms- classrooms- lounges- training areas. The OSSMT provides for automatic switching of incandescent lamps, low-voltage lighting with electronic and magnetic transformers, and electronic and magnetic fluorescent ballasts. The OSSMT features a manual override switch that can be used to keep lights off while an area is occupied, which may be desired in conference rooms, classrooms and other areas during video presentations. Designed to replace a single-pole Decora wall switch, it fits in a standard wall box. The OSSMT-md model requires a neutral and a ground connection. For retrofit applications, the OSSMT-GD model does not require a neutral wire for installation. Multi-Technology Wall Switch sensor, 2400 Sq. Ft. Major Motion Coverage, 400 Sq. Ft. Minor Motion Coverage, 800Wat 120v INC, 2400VAat 120v FL, 2700VAat277V FL, 1/4HPat 120v Motor, Commercial Grade - White California Title 24 Compliant. Wall Plate not included with Occupancy Sensors.

Al tener las dos tecnologías de detección ( infrarrojo y ultrasonido, se convierte en muy preciosa la detección, muy buen producto

Sometimes when the switch is manually turned off, the motion sensor won't activate the relay to turn the lights back on the next time someone enters the room. Probably works 60-70% of the time, so it's just not really reliable, especially for the price.

Works great, replaced once with respect to time-out settings. For whatever reasons, the timeout settings default back to 30min - great item, but not perfect.

Tested this today to see if it could trigger the accent lights as the bathroom door opened, from 6 feet height. With all three dials at max, it worked perfectly. The bathroom is 5' x 7' small and from that height only with the ultrasonic sensor could it detect the door opening before a person even appears. Also even from that height a person sitting low in the tub behind glass could trigger it with the slightest movement. Exactly what I wanted, expensive, but the normal occupancy infrared sensors didn't do anything I needed this to do!

My garage door opener's light failed. I traced it to a a bad circuit board which would likely cost me over $65 to replace. Instead of wasting time and money on an old opener I just decided to install one of these to turn the garage lights on. They're a mix of LED and incandescent lights which the switch handles easily. The combination infrared and ultrasonic sensor also works like a charm plus the the adjustability in sensitivity and time gives me far more options than a garage opener's light. The biggest bonus is that I no longer get yelled at for leaving the garage lights on!

We used these in two parts of the garage. They always work. I know the ultrasonic sensing works as the lights come on when I drive up 30 feet from the sensor when the garage door is open. Currently used with a set of 7 dual-bulb T8 fluorescent light fixtures on one switch and 4 dual bulb T8 fixtures on the other switch. Same unit used in our laundry room for two years without trouble. Beats turning on the lights when hands are full and trying to remember to turn them off.

I installed this to light up an alcove with LED undercounter lights whenever I was using my espresso machine. It worked really well for several days, until I actually installed the espresso machine. The presence of the espresso machine when it is turned on activates the light. I thought it was by PIR detection since the mahine is warm. I turned off the PIR detection using the rotary senstivity dial, but it still stayed on all the time. I suppose the ultrasonic detector can sense air motion from the warmed air rising up around the machine as well. The device is utterly useless whenever the espresso machine is on. I suppose that would apply to virtually any warm kitchen appliance as well. They mentioned several possible interferences, like people outside windows, air drafts from furnace vents and others. They neglected to mention that it was unusable around warm kitchen appliances as well. A complete waste of money. I was better off with my old manual switch. Now I have LED lights on six hours a day whenever the espresso machine is on.

Just got this installed yesterday in a master closet. that has a window immediate to one side at a right angle to the switch. However, the rest of the closet is shaped in such a way that even during the day, we need the track mounted LED lights to be switched on. Could have probably gotten away with a lesser switch since all we're using are:- 30 sec walkthrough timeout feature (don't understand when I would need the light to stay on even more than 5 secs after I leave the closet)- adjustable blinders to disregard the window and anything that may be moving outside- PIR/motion sensing (works well - switches on with just a hand through the doorway next to the wall switch)Probably didn't need the ultrasonic feature in this application. The shower on the other side of the wall from the switch did not trigger the switch in the least sensitive US setting.The switch does switch on with a very muted clickIt was an easy install provided you can determine which is the hot wire in the wall box vs the load wire. The instructions were not clear on how you'd remove the control panel cover on the switch without scratching or breaking it. But in case you're wondering, a fingernail in the top of the control panel cover should be enough to pry the cover off. A flat screwdriver or anything much harder than a fingernail may marr the cover.Would have liked the unit to also have z-wave control.

We installed these in the bathrooms of our office building and they work very well. We had some other sensors that were motion only and they did not perform nearly as well as these. These come right on when you walk in and the faithfully shut the lights (and exhaust fan) off. The instructions can be a bit hard to understand and I spent some time with their tech support on the phone and they were very helpful. One drawback I've noticed now that we've owned them for a while is that if someone comes in turns off the lights by pressing the button on the switch when they leave, it doesn't come back on automatically the next time a person comes in. I don't like that feature.

I originally installed an Infrared only switch from the local big box store. It was not reliable and the lights triggered the switch so once they came on, they never went out. Constant false triggering also.This switch with the ultrasonic sensor has been very reliable and triggers as it should. Much better product.A bit fussy to adjust, but once set up, works great. Very please, will only buy these in the future.
