Two switchboxes, power through light - how is this wired? You could even connect both lights to a single 87 which is how Hella's are usually done, i think most of their kit relays are only single 87 and no 87a NC connector. Pictured above is a circuit which takes an input from one (or more series-connected) PIR sensors.When motion is detected, the relay on the circuit board will close for from 5-80 seconds (user programmable) turning on a connected device – e.g. Check all wires for current with your voltage tester. Learn what a relay is how it works and why you should use one. An optional master control can be added that turns all lights in the facility on or off simultaneously under the control of a timer or computer. 3-way switch wiring diagrams for multiple lights. If there is more than one black wire connected to the switch, follow the instructions in step three. Very convenient. - I have 3 lights outside, one on its own switch, and the other 2 on a different switch. Wiring four lights on one switch, or daisy chaining as it is also called, is an efficient way to control lighting for homes and business. Use primary wire that's large enough to handle the current load of the new device. I would like to place In order to wire the 3-way switch properly, you will need to use one … As long as at least one motion sensor is detecting motion, the lights will remain on. The difference is that instead of flipping the switch with your finger, a relay has a coil that when power is applied, it makes the connection.
