The wiring was done very recently and, I'm certain, in accordance to modern code which may help you figure out the diagram, even if I don't know it. Predictably, one of the remaining mechanical switches stopped having any effect whatsoever. I was hoping, the second of the remaining mechanical switches will remain in control to allow explicit control of the light. This proved to be incorrect - sometimes it has an effect, some times it does not, and some times it disables the sensing switch it clicks, but the light stays off.
While the new sensor works perfectly well detecting humans on the same floor, if a person descends the stairs from the upper floor, the light does not go on until one descends to the middle of the stairs - when the feet come to about the same level, where the sensor is.
So I tried to follow Lutron's diagram linked to by mac and found it easy to connect the sole red wire on the 3-way mechanical switch to one of the black wires. Unfortunately, that did not improve the situation much. Depending on the position of the newly rewired mechanical switch, the sensor either works or it does not. I'm certain, I mis-wired the sensor when replacing the old 4-way switch with it.
Could somebody set me straight, please? In addition to ground, there were four wires connected to the 4-way switch duh! The new switch has 3 connectors: one blue and two black. What do I connect to what? I was only able to get it to work with two companion switches.
How to Install a Motion-Sensor Light Switch
The Lutron series does not work properly with two occupancy sensors. My goal was to get the apt on top and the entry way to have the lights turn on when the tenant or person entering opens the door. See the diagram and the description for 4-way. You could use some Insteon or similar home automation devices to have two motion sensors control the lights.
You'd need two wireless motion sensors and one dual-band switch. The switch receives the wireless signal from the motion sensors and activates the lights. You'd then deactivate the other two existing switches or add them back as "smart" switches, see below. When one of the motion sensors detects motion, it sends an "on" command to the switch. The motion sensor then starts an internal timer and if it does not see motion again before the timer expires, it sends an "off" command to the switch.
The only issue with this is that as you add additional motion sensors, you have a race condition to turn the lights off. This is likely not a problem for most scenarios, but if you have a super-long hallway or a giant warehouse that you're trying to cover with multiple occupancy sensors it'd be an issue. Hypothetically, lets say you have an infinitely long hallway with doors every 15 feet.
Over each door is a motion sensor, they all control the lights, and they're all programmed to time-out at 1 minute. Someone enters from one end of the hallway triggering sensor "A", which sends an "on" command and starts its internal countdown. As they walk down the infinitely long hallway, they trigger a new sensor every 15 feet or so, each sending its own "on" command.
As soon as sensor A's one minute timer goes off, sensor "A" sends an "off" command, and the lights go out. This is where a more sophisticated commercial light control network is needed.
But if you've just got three doors into a three-floor stairway, the two wireless motion sensors should work fine. If you expected people to linger in the hallway, you may have an issue, though you could just increase the time-out time to try to get around it. You could also add additional Insteon light switches if desired to replace the existing switches--though the motion sensors would still try to turn the lights off on you!By code, the number of conductors allowed in a box are limited depending on box size and wire gauge.
Calculate total conductors allowed in a box before adding new wiring, etc. Check local regulations for restrictions and permit requirements before beginning electrical work.

How to Read These Diagrams. The wiring diagrams on this page make use of one or more 4 way switches located between two 3 way switches to control lights from three or more points. Several diagrams are included here that can be used to map 4 way and 3 way lighting circuits depending on the location of the source in relation to the switches and lights. Included are a 4-way dimmer switch diagram and an arrangement that can be used to control room lights from four different locations.
Check here for 4 way switch troubleshooting and help with 3 ways switches here.
4 Way Switch Wiring Diagrams
For circuits that control lights from two locations only, check the wiring diagrams at this link. In this basic 4 way light circuit, 3-wire cable runs between all the switches and 2-wire cable runs from the last switch to the light. The electrical source is at the first 3 way switch and the hot wire connects to the common there.
The circuit neutral is spliced at each switch box through to the light fixture using the white wire. The black and red wires running between the boxes are connected to the travelers on each switch.
The common terminal on the 3 way switch at the end of the circuit connects to the black wire running to the hot terminal on the light. Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair.
Each pair of traveler terminals on the 4 way must be connected to only one 3 way switch. Don't mix up the pairs or the circuit will not work properly. This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after. Two-wire cable is run from the light to SW1 and 3-wire cable runs between the three switches. The source neutral wire is connected directly to the light fixture and the hot is spliced to the white cable wire running to SW1.
At SW1 it's spliced to the white wire running to the 4 way switch box where it's spliced to the white wire running to common terminal on SW2. The white wire is marked with black at each splice to identify it as hot. At SW1, the common terminal is connected to the black wire running to the light fixture hot terminal. The black and red wires running between the switches are used to connect the travelers on each switch.Variety of motion sensor light wiring diagram. A wiring diagram is a simplified conventional pictorial depiction of an electrical circuit.
It reveals the elements of the circuit as streamlined shapes, and also the power and also signal connections between the tools. A wiring diagram usually provides details concerning the loved one position and plan of gadgets and also terminals on the devices, to assist in structure or servicing the device. A photographic representation would reveal a lot more information of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is usually made use of to repair troubles as well as making certain that the connections have been made which every little thing exists. Collection of motion sensor light wiring diagram. Click on the image to enlarge, and then save it to your computer by right clicking on the image. A wiring diagram is a kind of schematic which utilizes abstract pictorial icons to show all the interconnections of parts in a system. Electrical wiring representations are comprised of two points: symbols that stand for the parts in the circuit, and also lines that represent the links in between them.
From wiring diagrams, you know the loved one place of the parts and how they are connected. Circuitry layouts mostly reveals the physical setting of parts as well as connections in the built circuit, yet not always in reasoning order.
It stresses on the format of the cables. Schematics stress on exactly how circuits work realistically. To read a wiring diagram, first you need to know what basic elements are consisted of in a wiring diagram, and also which photographic symbols are used to represent them.
The typical elements in a wiring diagram are ground, power supply, wire and connection, outcome gadgets, switches, resistors, reasoning gate, lights, etc. A line stands for a wire. Cords are made use of to connect the components together. All points along the cord equal as well as connected. Cords on some places should cross each other, yet that does not necessarily imply that they attach.
A black dot is made use of to suggest the injunction of 2 lines. Main lines are represented by L1, L2, and so forth.
Generally different shades are made use of to identify the cables. There must be a tale on the wiring diagram to inform you just what each shade implies. Typically circuits with even more than 2 parts have 2 basic sorts of links: collection as well as parallel.Automatically turns the lights ON when motion is detected and automatically turns the lights OFF when motion is no longer detected.
Synonymous with motion sensor or motion detector. Lights must be manually turned ON but will automatically turn OFF when the room is vacant and motion is no longer detected.
An occupancy sensor is technically more capable than what is commonly referred to as a motion sensor or motion detector but an occupancy sensor or vacancy sensor is in fact a motion sensor or motion detector. A motion sensor or motion detector is terminology typically used in the home or residential market while the term occupancy sensor or the term vacancy sensor is typically used in the professional or commercial market.

When Lutron contacted me to see if I would be interested in installing their occupancy sensor light switch in our home I thought, this is the perfect opportunity to try something new and possibly save on our electrical bill. Living with four generations under one roof, the lights get left on all the time and we never know who did it.
We have had these switches installed for two weeks now in two of our bathrooms and we LOVE them. So much so that my dad wants more of them for the rest of the house. Stay tuned, Lutron is giving away a occupancy sensor switch to one of you in a bit!
My brother and I installed the Lutron Occupancy Switch together in one of our bathrooms and I created a video of the installation. For me, I am a visual learner and I think seeing the wires and how we installed the switch will help you if you are a bit intimidated by this project.
Like I said earlier, I have never done any type of electrical work so this project was intimidating at first. Lutron provides detailed installation instructions as well in the packaging. Below is quick tutorial on how we installed the sensor. Step 2: Remove your existing light switch plate cover and pull out the existing switch from the wall. Step 3: Remove the existing switch by unscrewing the two screws holding the wires in place. Depending on what type of existing switch you have, this may be different.
Step 5: Tie the silver and green wire together on the back of the Lutron Occupancy Sensor as shown in directions and above video and connect to the existing ground wire in your wall.
Use the yellow nut cap supplied with the sensor to fasten all the wires together. Screw the yellow cap until it is tight as shown in video. Step 6: Connect the two black wires on the back of the sensor to the two wires from your wall. Use the yellow nut caps to fasten the wires together. The same as in step 5. Step 7: Once all the wires are connected, tuck the wires into the wall hole as neatly as possible.
Fasten the sensor to the wall with the screws provided. The sensor offers a very modern and stylish look which is appealing to the eye. Are you ready to win your own Lutron Occupancy Sensor? Winners will be notified via email and will have 48 hours to respond or another winner will be chosen. Good luck! I chose to have the light come on at the high setting high sensitivity and shut off after one minute of no motion.Motion detectors and occupancy sensors can detect movement and then cause an event to happen.
They are commonly used for security and saving energy. When the sensor in a security flood light detects movement, it tells the switch to close, and light s turn on. After a certain amount of time, the switch will open and light s will turn off. Some motion detectors and occupancy sensors have adjustments including how long light s stay on without detecting movement.
Occupancy sensors are commonly used in offices and classrooms. They can also be used at home in closets if lights are usually left on. Occupancy sensors can replace light switches, or can be mounted in the ceiling. They detect motion in the room and control lighting automatically. If no motion is detected after a certain amount of time, lights turn off.
Lights can be turned on and off manually with a button or switch on the sensor. Some occupancy sensors have adjustments including how long light s stay on without detecting movement. Motion detectors can be used for many different applications. When motion is detected, a light is turned on or an alarm is activated.
They can be used for:. Supermarkets are using them in aisles and freezer sections to turn lights on when a customer comes near, and will shut off after a certain amount of time. This works well if a store is open 24 hours and there are very few customers at certain times.
Occupancy sensor switch wires each have two black wires, or one black and one red and ground green. One of the black line wires connects to line voltage from the panel, the other black or red load wire connects to the light s. Each black wire can be a line or a load.
Red is always the load wire. A typical occupancy sensor needs a good ground connection to operate properly. Dimmer Switch Wiring. Ceiling Fan Switch Wiring. Question or Comment? Occupancy Sensors Occupancy sensors are commonly used in offices and classrooms.

Occupancy Sensor Wiring Diagram 1.A motion sensor light switch is a great way of saving energy and helping out the planet by making your home greener and more energy-efficient. A motion sensor light switch will automatically detect when someone enters the room and turn on the lights. Then, after a few minutes where no movement has been detected, the lights will then automatically shut themselves off. If you're the type of person that frequently forgets to turn off the lights when leaving a room, this type of light switch can potentially save you hundreds of dollars a year in energy costs.
Although a motion sensor light switch is indeed a marvel of technology, the installation of the switch is relatively simple. In fact, you install a motion sensor light switch much in the same way as you would a single pole light switch regular lever type switch.
This article will address how to wire a motion sensor light switch when replacing an older lever type switch. Before getting access to the electrical box to work at it, the main circuit breaker must be turned off at the source to prevent anyone from getting an injury or electrical shock. Whenever you purchase a motion sensor light switch, you will notice that there are many wires on the back of the switch. Once you see this, you might get the idea that the installation of the light switch is complicated and something you might not be able to do yourself.
However, nothing could be farther from the truth. In fact, installing a motion sensor light switch is a simple DIY project that almost anyone can do. Generally speaking, you wire a motion sensor light switch much in the same way as you would a regular single-pole light switch.
In basic installations, you will only need to worry about connecting three wires: the Hotwire, the neutral wire, and the ground wire. As mentioned above, you will see many wires on the rear side of a motion sensor light switch. However, you only need to use three in most applications. When you look on the back of the motion sensor light switch there might be five wires that appear like they should be connected somewhere. These wires include the three basic wires always present in switches, and sometimes two more wires for three-way switching.
Those two wires will usually have some sort of label attached to them as well. The two wires glued together are for use in a 3-way switch system, where a single light is controlled by two switches.
However, if you'll only be installing a single switch as for this case, even if the switch has the five wires, you don't need to worry about those last two. It is only the other three wires that you need to be concerned with when installing a motion sensor light switch.
The colors of those wires are usually black, green, and red. The black wire will be connected to the black wire that comes out from the switch box. The red wire is connected to the white wire that comes from the switch box, and the green wire is always used as the ground wire. When connecting the ground wire, you will either connect it to a green wire or a bare copper wire.
