3 PIR's Lighting Control - Wiring Diagram Part 2

[@jmohammad3762]

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 👍👍👍

[@Dibbo1979]

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

[@kabandajamir9844]

The world's best teacher thanks

[@tigergkw2498]

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 :-)

[@brianoceallaigh8714]

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...

[@tigergkw2498]

Great.....just 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 :-) . Now.....how to get that wiring done in practical terms.....here we go.... !! ;-)

Great tutorial! Thanks for the upload

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.

Thanks Matt 👍

[@Hussking84]

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

[@pjcartlidge]

Fantastic, thanks 👍

[@alfonsputzeys9228]

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

[@CH-en4er]

great video thank you

[@GSHElectrical]

Thanks

[@eddie_pegasus_electrical]

Excellent vid for learners

[@phough5247]

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

[@motoxali13]

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

[@GSHElectrical]

Yep

[@ianweatherley2467]

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

[@gczz]

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.

[@ravigrover11]

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

[@eksine]

will not damage, they are all doing the same thing: connecting load (light) to the HOT, the motion sensor is simply acting as a relay triggered by infrared detection

[@matthewo6077]

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

[@BerHarSenSam]

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

[@Yahatacooky]

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

[@jackinfo121]

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

[@GSHElectrical]

On Site with Matt PIR Contactor Controlled Lighting Circuit with 3 Position Switch. How do they Work kzbin.info/www/bejne/bGnVpIqdh9CHapo

[@ThomasLouttit]

Can someone please tell me how the Load ratings of these PIR motion sensor switches?

[@Paulryan84]

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

[@bigbud1978]

That’s what I was also wondering?

[@paultipton743]

I would take the neutral from the nearest pir as the neutrals are linked through anyway

[@mattyourell609]

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

[@Ukman-england]

Is it live and earth on the switch

[@christianjohnson7036]

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.

[@javandermerwe]

Correct

[@eksine]

@@javandermerwe you are both wrong, the bypass switch is intended to turn the lights on, an over ride, however he drew the diagram wrong anyways because he drew it between the wrong 2 PIR sensors, it needs to be on the same location as where the load is.

[@RanjeetJagtap007]

How to connect 3 PIR sensor with one siren?

[@nanageneral756]

Can I use the same method to wire 4 microwave sensors to operate one bulb?

[@MonaichFother]

Why not, jinthis example he just chose to show three.

[@MrEndzo]

What if I wanted to have the override to be able to turn the pir off? Edit: found the answer later in the next part

[@baldyslapnut.]

As drawn your PIRs look like they're in series. To get them in parallel you'd need a JB with a second SL feed from a 2G switch, then 3C+E from that JB to each PIR wouldn't you?

[@darrenowen3338]

To be in series, the output (switched live) from one would have to be the feed (live) for the next one, and so on. You'd either have to activate all three to get your lights on, or the inactivated one(s) would be redundant.

[@baldyslapnut.]

@@darrenowen3338 yeah, see it now. Must have been half asleep last time I watched😴. Thanks 👍

[@brianhewitt8618]

👍

[@tigergkw2498]

Am I right in saying that if a potential burglar decided to rip one PIR out from that set-up, then non of the others could still act independently ?? I want to wire mine up so that if one PIR was ripped out, then the other two could still work independently and be more of a deterrent. A diagram of how to wire a circuit the way I would like to do it would be very helpful, I can see me having wires here, there, and every bloody where !! 🤔😳

[@MK-wf1eg]

I'm guessing we use 3 core and earth from supply?

[@loosecannon5813]

Yes, I run interconnected smoke alarms like that as well. Remember to terminate the switched live properly within the consumer unit.

[@jamesgledhill9667]

Only need twin and earth from supply. Then three core between pir. Then twin and earth to light

[@loosecannon5813]

When I run the 3 core back to the consumer unit, I've then got a switch line which can be easily 500v insulation resistance test, also I can add and have added additional interconnected smoke alarms from the board.

[@jamesgledhill9667]

@@loosecannon5813 what's smoke alarms got to do with it? You only need switch wire from pir to light.

[@eksine]

Your bypass switch is not drawn correctly, if those 2 PIR are off on the switched side your lights will not turn on because the lights are wired on the switched side between the 2nd and 3rd PIR, you have drawn the bypass switch between the 1st and 2nd PIR which is not the same location as the load (lights) , please take a look at your diagram again and look at where your load is in relation to the PIR's

[@cecilandrews7479]

Your drawings messed up, you don't have a neutral line going to the lights. Somebody following this he'll be saying Hell my lights don't work

[@persian_warrior1]

this is not for someone who doesn't have any clue about electrical. thanks for the video. now, I simply know how few pir could work and control the lights in one go at different locations. ❤❤❤
