Security light wiring

[dantheram]

Firstly hello all,

Secondly i'm not a spark just after some DIY advice so go easy :wink_smile:

I'm trying to wire in an outside light with PIR.

inside the house i have this set-up -

Switched FCU - - - -WALL - - - - PIR light
(3core) (3core)

I would like the SFCU to turn the light on permanently in on position and to PIR activation in the off position. If this is too hard to achieve, or requires another switch adding i will just buy a PIR light with the pulse permanent on function.

P.S. light spur can be isolated by removal of fuse from another FCU further back, feed side.

let know your thoughts, thanks.

Dan

Grid switch !

There,that should help the quest

2 gang yoke
grid fuse
2 way grid switch
2 gang faceplate

Just had a eureka moment

MK Grid Wiring - Grid Wiring | Screwfix.com

i guess i use the grid fit stuff on that link to build a 3a fuse next to a 2 way switch.

correct??

 

[dantheram]

big thanks to everyone who replied.

off to buy the stuff and i shall report back with the results / disasters

Well done des 56 for the suggestion. Didnt think of this solution. Sorry to mislead you dan!

 

[dantheram]

Quick novice question again.

Live from spur to fuse feed side

live from fuse load side to com on switch

l1 and l2 carrying live and s/live to light

what do i do with the neutrals? connect them together?

Dan I think you might have brought a two way switch. If so just connect your switched live to L1, if it appears that the switch is upside down, use L2 instead. Connect the neutrals together. Your permanent Live to light will go into com with the link from fuse. When using a two way switch as a one way, some manafacturers use L1 others use L2.

Unbelievable.

There are several ways to skin a -----........

What you need for this recipe :

One two way switch plus one connector block

How to wire it up :

I can't believe I wrote that

How it works:


Well i found it hard to beieve that I wrote that


Guess where you stick the cpc?
Remember to whistle colonel bogy when you insert it !

Now, I can believe that i wrote that

a big +1 on that.

Thought tonight had gone too smoothly.

Is it so hard just to give a straight answer?

I'm following someone's advice and, as a novice, just wanted to clarify something.

I'm pretty sure I know how to do this but as people on here will obviously know better I thought why not ask.

start with your FCU. from there feed a bog standard light switch. from this switch you need a 3 core/E to the PIR light. brown in common with the L from FCU. black in L1. N's in a connector Blue from FCU to grey of 3core, sleeved blue). then at the fitting, brown to Lin. black to Lout ( connected to light internally) , grey ( sleeved blue) to N in. connect cpcs to earth terminals.

edit: sleeve the blacks with a bit of brown sleeve or tape.

Spot on, thanks.

So if using Des' suggestion (grid assembly - fuse and 2 way switch) I can just connection block the neutrals together. As this is the same as you're suggesting with your setup.

connector block is fine as long as it's accessible, which it is if in the switch housing. and how i described it, you only neeed a 1 way switch. if you already have a 2 way, use common and L1.
