Dual Master Wiring

I need to wire two lights that each have a motion sensor built into them, so that when either light detects motion both of them will come on. This is referred to as a 'dual master' configuration. Can anyone give me ideas, links or help?

Hzsupport.com shows the wiring diagram, the red wires go together.

    Only if both detectors are on the same circuit.

    Or on the same phase in the panel.

Consult an Electrician and ask them to install a contactor and use both switch legs to activate the same coil. Then you can add multiple lamps to the contacts of the contactor. The coil will stay "active" until the last trigger time is complete.

    Again, if both detector are not on the same phase, the coil will blow up, when both are activated.

Do you have a wiring diagram to wire a security motion detection light between 2 3-way switches so switches can be turned: (on-Motion)/(on- Completely) from 2 differemt locations?


One of the switches needs to be a 4-way then the PIR will act as any other switch. The downfall is if the lights are on and motion is sensed they will turn off.

My preference is to connect the contacts of the security device across the travelers of the three way circuit. The travelers are probably the red and black in the three conductor cable. When motion is detected the lights will turn on regardless of the settings of the three way switches then after timeout they will turn off. If they are turned on with one of the three way switches nothing will happen when the motion detector turns on except you cannot turn the lights off until the security device has turned off.

I hope this helps. The motion contacts need to be isolated from the motion detector power.

Here is a page of diagrams: http://www.do-it-yourself-help.com/3_way_switch_wiring.html
You have to use a 3 way switch on both sides. You should be able to get a motion light that has an always on feature. To activate the feature then you need to turn the light on off on fast and then it stays on. Ceck with home depot or someplace like that for lights with that feature. IF not then you are going to need to run another circuit.

Lights flash on and off


Very common issue with motion sensing lights. You can either replace the light sensor which is available at most hardware stores or you can disable the motion sensing feature and just have an on-off light. To disable the sensor, (turn off the power!) unscrew and remove the light sensor (it is the reposition-able box under the light.) It depends on the particular light, but you usually just match up the wire coming into the light from the house and the wire from the bulbs and connect them with a wire-nut.

I want to replace my existing single bulb porch light with a 2 bulb motion activated light. It would be operated with the existing switch. Is this ok to do?


Yes. Must keep switch turned ON.
Outdoor lights will only come on when motion is detected, otherwise light bulb does not come on. So the indoor wall switch does not work as override since the motion sensor takes over as the sole switch.
Copy following link for wiring illustrations:
http://waterheatertimer.org/How-to-wire-occupancy-switch.html#motion
Other solutions include adding separate motion sensor light nearby and keep porch light so you can turn on-off when desired.
Another option is to add photocell to outdoor light so it turns on automatically at dusk.
Another option is to use outdoor yard timer with dawn-dusk capability:
http://waterheatertimer.org/Woods-timers-and-manuals.html#outdoor
Another option is to replace indoor wall switch with with dawn-dusk timer, that can also be used as ordinary on-off switch so you can turn porch light on-off when desired. Timer such as Intermatic ST01C offers simple 2-wire connection.:

User manual for fl09sbk light


It appears this device is rate 10 amps at 230 volts = 2300 watts.
Use at least #14 wire and 15 amp breaker.
Connect wire at connection point on light.
Unit appears to have a transformer, and might make humming sound.
There is override located somewhere on unit. Possibly as a button on the motion sensor

If infrared motion detector requires separate wiring connection, then use following wiring illustration:
http://waterheatertimer.org/images/How-to-wire-motion-sensor-230V.jpg

Motion sensor will probably have 2 settings.
1st setting for sensitivity, so it will not activate when cat walks up driveway.
2nd setting for time duration, selectable from 30 seconds to 7 minutes

You are replacing porch light with light fixture with motion sensor device.
Each light has 1 black and 1 white wire.
The motion sensor has 1 black 1 red 1 white:

I installed the PR180 switch in my garage with a 4ft dual t-8 flourescents bulbs. When the motion sensor timer turns the light off the flourescent bulbs stay slightly lit, as if it were on a dimmer...


There is nothing wrong with the switch or your wiring. The Leviton R01-PR180-1LI is not designed to work with flourescent lights. A lot of electronic controls will bleed through a small voltage when in the "OFF" state. It's just enough voltage to make the ballast in the flourescent light try to fire but not enough to let it fire the way it is supposed too.

What you need is a motion switch that is rated for flourescent lights, such as this :-( :

We bled the breaks...why is my break light still on?


By bleeding the brakes you cause uneven pressures in each half of the dual hydraulic system. Therefore, the sensor switch that detects this pressure imbalance has operated and will remain set as indicated by warning light. The switch is either located on the side of the Brake Master Cylinder or on the proportioning valve on the firewall.
To reset detecting switch, first disconnect wiring plug (Light should go out with plug disconnected) and remove switch. You may hear a click as the pressure difference piston resets as you remove the sensing switch. Pump the brake pedal a couple of times to ensure piston has reset and then replace switch and wiring connector.

I purchased the dual brite motion sensing lights and put two of them on my garage, i wired them from a switch to either side of the door on one circuit allowing them to be individual sensors but i keep...


are you using fluorescent bulbs? I had the same problem in my stairway/hallway till I switched to master/slave. Why don't you want master/slave? What's the diff?

I think each switch allows a certain amount of current to pass...with one switch, it's not enough to light the bulb; two switches, you get a faint light.
