Have a question for you regarding some wiring for some external lights.

I have a standard light to go outside my back door, a seperate PIR sensor and another light to go above my garage.

I want the seperate PIR to switch both lights when it is activated, but also want to use the switch just inside the back door, so manually switch the lights on if i was going out of the house at night....

Any idea if this can be done??? and if so, how???

Cheers

 

2 secs.... in paint doin a diagram...

 

Permanant Live and Neutral into the PIR. Switched live and neutral out of PIR into the lights - either split using a junction box, loop into first light then into second, or have two sets of wires going out of the PIR. THat will be ur lights up and running on the pir. Then, for overide switch, take a wire from permanant live, into a swicth, out of the switch and to the one of the live terminals on either light. U only need to goto one of the lights lives, as they are already connected via the PIR.

Note that a lot of pir's provide an overide, even when its not documneted. U usually have to swicth power on and off to it within a couple of seconds

 

feed the switch from another light or from the main board.

wire from the switch a 3 core to your pir.

wire from the switch a twin and earth to your light, then from light to light.

in the switch (black box area) connect both live feed and live to the pir in L1 or common whatever its called.

put the return from the pir (either switch live or * or whatever) in with the outside light live on the other side of the switch.

put both neutrals in a connector block.

giving.. pir or switch operated lights.

 

Top replies Fella's....

Big thank for the time to draw it out too...

 

not a problem dude, if you get stuck....




get the yellow pages out

 

good thinking....

use it to stand on to put the light up outside....

 

It appears that both of your responses are slightly different...

Is either way any better/easier than the other???

 

In the first one, the switch and PIR are wired in series.
-Switch on, PIR activated = lights on
-Switch on, PIR not activated = lights off
-Switch off, PIR and lights off
-Switch off/on quickly, PIR goes into permanent ON mode, until you switch off/on again.

In the second one, the switch and PIR are wired in parallel.
-Switch on = lights on, regardless of PIR activated or not.
-PIR activated = lights on, regardless of switch on or off

Downside with the second one is that you can't switch the PIR off if you don't want it to trigger for some reason.

Hope this helps, and that I understood it all ok.
