    4 way motion sensor (outdoor)

    I am installing landscape lighting for a client and i have run into a slight challenge.
    The lighting will be controlled by a switch and the switch will be left on
    always. After the switch I am trying to include 3 outdoor motion sensors
    that will turn the lights on. Scenario: property has three driveways and
    lights will turn on (hopefully) as you enter any three driveways.
    Do they make a 4 way outdoor motion sensor?
    Sensors will of course be at the beginning of each driveway entrance.
    Any input is appreciated.

    Parallel the sensors, doesn't matter if you have two sensors or two hundred, any one sensor calling for illumination will turn on lights, all sensors must be calling for darkness before lights go off.

      Are the lights going to come on during the daytime if someone drives in during daylight hours? Or are you going to have a photocontrol or timer before the switch?
      You make the lights come on and we make them go off.

        4 way outdoor motion sensors

        Yes, there will be a photocell as the power leaves the house panel.
        The switch is just for the home owner to turn off in case he wants them
        completely off at night (amazing star gazing in this part of town).
        Im assuming the sensors will have an option for the timing..5 min, 10 min, etc.
        I am aware that after the switch(always on) and photo cell, power enters the first
        motion sensor(black/white), then travelers continue to the second motion sensor and then
        onto the third. The lighting circuit is then connected to third(last sensor).....similar to a
        4 way in a hallway.....for example. The travels are what have me stumped and I am
        not even sure if they make a 4 way outdoor motion sensor. My question is really about
        the wires leaving the first motion sensor....going to the second and then the third. And
        have no idea what the back of a 4 way sensor wire configuration looks like.
        Thanks everyone and I am open to advice on brands of outdoor 4 way motion sensors also.

          No such thing as a three way or four way that I am aware of, and you wouldn't want such devices either. If sensor 1 detected activity and turned the lights on, then comes activity at sensor 2, the operation of the second sensor would turn the lights off, you want to parallel single pole units like I described in post 2. Any activity on any sensor turns lights on. All sensors must see no activity and finish timing out before lights will turn off.

            Think of it as an interconnected smoke detector system - all the reds get tied together, so when any sensor detects movement, they red wire feeds power to the lights (and backfeeds to the other sensors as well). So you need a hot and neutral to first sensor, then three-wire from there to the load. If the customer wants the lights dimmed, the dimmer would go between the last sensor and the load.

              Three wire would run between all sensors and then two wire between last sensor and the load. Additional loads can be attached anywhere along the three wire portion of the circuit though.

                This post covers a few responses. I guess it should not be called a 4 way because once one sensor activates it should lock the other sensors into the same position internally, and it cannot be altered from any sensor until timed out. I would assume that by driving by a second sensor that it would not do anything since it is already activated......right?
                For PetroA.....your answer sounds like it will work. The back feeding part is the part I am figuring out but is making a little more sense now. As mentioned above, yes, once one sensor is activated then all sensors need to be activated for the duration of the sensors time selector.

                I need to get a motion sensor( that will coincide with 2 other sensors) and check the wires on it.
                Or can I use a typical motion sensor?

                I've included a photo of the layout.
                Scenerio 1: car enters property.....lights turn on.
                Scenerio 2: car leaves property from house area....lights turn on.
                Scenerio 3: car is parked in parking area and leaves property.....lights turn on.

                Sorry....photo could not be attached at this time.

                  If anyone is up for drawing a quick schematic that would be helpful.

                    Thanks everyone!!! I found a schematic on www.renovation-homeowners.com
                    Its under the "wiring more than three sensor section".

                      You will be paralleling all the sensors. Just because one is activated doesn't mean the others need activation, they are activated by motion not by signal from other sensors.

                      I couldn't get your link to work, here is my drawing of what you need to do:


                      If sensor one senses activity its contact will close sending power to the load. Sensors two and three could care less if the load is on or not. They will close their contacts if they should detect activity, keeping the load on even if detector one stops sensing activity and opens it's contact. When there is no activity on any of the sensors all contacts open and load is deenergized.

                        Thanks for catching that mistake. I think too fast for my keyboard sometimes

                            So there's a couple things you could do.

                            You have three driveways. Do you want to turn on ALL the lights to every driveway no matter which one they enter or leave from? Or, just one driveway where the sensor is located?

                            The easiest way to do it is with low voltage relays. You could also use a wireless system, like Hubbell's WiHubb or NLight by Sensor Switch. Wireless is easy to install but can be pricey, especially for such a small system.
                            I know lots about lightbulbs!

                              Since there is only one switch leg, paralleling the sensors is the only way I can see to hard wire this. Seems like a lot of work though.

                              If this was a covered area, Lutron makes some great battery powered occupancy sensors (they last for at least 5 years) which can be paired up with a single Maestro RF switch (within 30 feet). We swear by these things and even though they're for indoor use, we've had one in a covered driveway for 3 years now and it hasn't missed a beat. That's the cheapest no fuss way I can think of getting this done if you can protect the sensors from the elements. If the house already had a lighting automation system from Lutron or Vantage Controls, the low voltage solutions would be very easy.
