3 PIR's Lighting Control - Wiring Diagram Part 2

Matt looks at the basic wiring diagram for a circuit controlled by 3 Passive infrared sensor (PIR). He looks at the working principles for controlling a circuit by a remote PIR to control things such as lights. In part one Matt looks at the wiring connections in both the PIR's and the use of a one way switch to override the PIR''s.

Another great video from GSH Electrical Tutors. Love with way these guys make the connections looks simple. Perfect for a novice like myself. Top Team 👍👍👍

In the end I decided to wire my 3 PIR's and 3 security lights exactly the way you illustrated. And they work a treat :-) . Of course, they'd never pass any sort of inspection, but they'll do me for now. Thanks very much for your help :-)

That felt tip noise went right through me😂. Great video mate

[brianoceallaigh]

Good one Matt, My profile picture is what your video is about, been wiring quite a lot of lighting circuits of late especaily in factories where no light switches are used... Enjoy your videos Matt, top class...

what I was looking for to wire 3 PIR's and associated lighting round a detached garage after a recent attempted break-in !! Thanks for taking the time to help us non electricians out :-) . to get that wiring done in practical we go.... !! ;-)

My prefered way of achieving this with outside lights is to wire a seperate 3 core to pick up the PIRs and then a seperate cable, either 2 or 3 core to the lights. Run the cables back to the dis board and make a wago joint in a labelled adaptable box. You can go a step further and run individual cables to PIRs which can allow easier fault finding when they eventually go wrong, down side is extra cost of cable.
With corridor lights you can run common 3core through all lights and PIRs, the only problem can be if you need emergency fittings that are to be tested with the remaining lights staying on, in which case you need an extra core or self test fittings.

I never tought of this solution.
My schematic relied on a 2pole 2 way switch to switch between power from the pir and mains power.
But the use case is similar.
2 to 3 pir that control 4 led flood lights.
To light up the area around the house and the gras area ontop

Hi. So I've wire one 2 pir's, then connected two led 20w floodlights to the switch live, neutral, earth. It works but when the leds are in standby, half of the little leds are slightly lit up. Is this normal? When you fully unplug power the lights completely go out

Thanks for the video. Do you know if this will work with any two PIRs?

[BerHarSenSam]

Great. Thank you. It looks like having more than one one-way override switch would work as well?

I have a very specific case going on here that I'm not sure how to handle. I've installed Led tape lights underneath both sides of my bed. I've installed one PIR sensor on each side, so the idea is that only one side would light up at night when detecting presence on respective side. Because I have a lack of wall outlets, I'm trying to use only one power supply, so basically each led light and sensor are in parallel with the power supply. The issue is, this PIR sensor closes the circuit up when it's connected to power, before actually opening it and waiting for "presence", so when one side detects presence, it lights up, but when it powers down, the other side lights up immediately, as if the sensor had been connected to power, and it keeps doing this alternation a few times before it switches off completely. I'm thinking two diodes might do the trick, but I'm not sure.

Question at 1:48 you are drawing a line what is the cable linking all PIR ? Is that the black on a 3 core twin and earth cable or a separate cable??
Can you identify that plz
Cheers

[ravigrover]

Hi what happens if 2 motion sensor are activated at same time in this circuit.will it damage the load.

I want to attach 3 motion sensor to a bell to be used as burglar alarm. One motion sensor infront of each door which connect to a bell.
Pls suggest

[ianweatherley]

Can the Lamps share the same neutral circuit as the PIR's?

[Yahatacooky]

Great video but what if the PIR has an additional two terms marked D1 & D2?

[matthewo]

Can you have an overwrite switch on each PIR so you can tern the one off you don't want .

[christianjohnson]

Gteat video thanks!

Quick question - am I right in thinking that if one of the PIR's were activated and turned on the lights, you couldn't then use the one way switch to then turn the light off could you? I'm guessing youd have to wait until the time set on the PIR had expired.

[Paulryan]

Hi. Would you take the neutral from the PIR’s to the light or would the light need to go back to the board ? Cheers

[mattyourell]

Can you do this with lights with integrated PIR's or do you have to have separate PIRS to achieve this?

[jackinfo]

hi. just wonder why the need of override switch? thanks
