Two Motion Sensor Lights On One Switch

The motion sensing device many have adjustable sensitivity to limit its range a timer that starts when the motion sensor activates many have adjustable timers to adjust the amount of time a light hooked to it will stay lit a photocell that deactivates the switch during the daylight.

Two motion sensor lights on one switch.

If the light switch is currently off turn it on and leave it on. Install the light bulbs and turn the circuit back on. This will allow you to connect the first light as you described above and to run this additional light from the same switch by utilizing the red conductor in the 3 wire as the switched conductor and the black wire as the continuous hot wire. Your reply of 22 dec concerning wiring two outside motion lights to one switch i am determined to run those two pir 2es sensors to one lamp.

This now does not work. The way to wire two or more motion detectors to control one or more outdoor light fixtures is to wire a control circuit where the motion detectors are connected to one control relay and the control relay will turn on the light fixtures. As long as at least one motion sensor is detecting motion the lights will remain on. Once it becomes darker outside adjust the sensitivity and range on the motion sensor so it works the way you want it to.

Installation instructions for each motion sensor light say there should be no other lights on the same circuit. The fixtures should all turn on for a few seconds and then automatically turn off. I would like to replace the lights on the outside of my garage with 2 motion sensor lights on the same circuit to the same switch that the old lights used. I understand now that that configuration is likely to confuse the sensors and you may well end up with one sensor in one mode and the other sensor in another mode.

Here again both units worked with one switch befor the new electrical wiring but now only the motion detecor works. Most have four components. Each of the motion sensors must be individually rated to handle the total power load of all of the lights that you wish to turn on. The electrician now ran two lines from the switch one to each motion detector.

Wiring two or more motion detectors and light fixtures. For example if i enter the hallway and trigger motion sensor 1 to turn on the light then walk down the hall and remain by motion sensor 2 the light will turn off when no motion is sensed by motion sensor 1 even though motion sensor 2. I have the same situation with one switch controlling a motion detector light and a day night. A motion sensor to turn on a light is nothing more than a fancy light switch.

The turn off function is only determined by the switch that turned on the light.
