Two Motion Sensors To Control Three Lights
Simply wire the two sensors in parallel. Hot to black wire of both sensors,
white to white of both sensors and white to lights, and red from both sensors to black of lights. Whichever sensor picks up motion activates, and yes it backfeeds the red load wire of the other sensor, which does nothing because it's relay is open. If they're both activated, they'll both time out normally. The one thing you can't do is feed the sensors from separate power supplies wrote in message ... Would like to use two motion sensors (the ones sold individually and not connected to any lights) to turn on three flood lights. The idea would be if either motion sensor was tripped the three lights would go on. My thought was to connect the switched side of the one motion sensor to the three lights and to the switched side of the other motion sensor. So it would be: (Hot Wire) Motion Sensor[A](Switched Wire)Light(Switched Wire)Light(Switched Wire)Light(Switched Wire)Motion Sensor[b](Hot Wire) My concern is that the current applied to the motion sensor that is NOT activated when the other is activated may damage the motion sensor. In other words if Motion Sensor [A] is tripped it would allow current to flow to all three lights and the switched side of Motion Sensor [b]... would that damage Sensor [b]? Thanks, William |

Thanks, William- Hide quoted text - - Show quoted text - Wouldnt you blow the circuit if both trip, you will be feeding 120 to itself. X10 has remote units that can trigger many lights, when I pull in the garage 4 sensors go off, with 15 lights, the garage sensor triggers 3 more through a code that goes through the AC lines. one in garage, two outside, one inside, and 3 button garage remote are compatable. X10 also has battery powered RF sensors and interior keypads and a computer program it sells. Cheap home automation. |

Two Motion Sensors To Control Three Lights
All these devices have wattage limitations. Garden variety motion detectors
are 300 to 500 watt. There are others available with higher switching capacities as well. If you wanted to control lighting from multiple circuits or higher wattages than the motion detector is capable of, you'd need to use relays or line carriers to do it, but I would always opt for simplicity if possible "ransley" wrote in message ...

Thanks, William- Hide quoted text - - Show quoted text - Wouldnt you blow the circuit if both trip, you will be feeding 120 to itself. This is why you must use the same feed to both motion detectors. In the event that you used a leg of different potential, you'd blow the detector X10 has remote units that can trigger many lights, when I pull in the garage 4 sensors go off, with 15 lights, the garage sensor triggers 3 more through a code that goes through the AC lines. one in garage, two outside, one inside, and 3 button garage remote are compatable.
