i bought a pir sometime ago and lost the wiring diag for it could anyone help me with the wiring the pir has four connections, from left to right they are red,blank,blue,brown,
the actual light is blue, brown and earth which is switched from inside the garage.
any help would be most appreciated
AS for the red and brown, one is used for your existing BROWN live
if you connect to wrong one the light will just stay on (USUALLY TWO INTERNAL WIRES already CONNECTED in terminal), if you connect right it will go through the sensor (USUALLY ONE INTERNAL WIRE already CONNECTED in terminal)
Look at the light you can work out, as you see the internal wire go to sensor, back from sensor , then go to lampholder plus neutral back from lampholder and neutral to the sensor
Dont forget to earth on the earth terminal where the GREEN/YELLOW wire is
