PIR Lighting Control - Wiring Diagram Part 1

PIR Lighting Control - Wiring Diagram Part 1

Matt looks at the basic wiring diagram for a circuit controlled by a 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 and the use of a one way switch to override the PIR. This series of videos continues on to look at more complicated uses of PIR controls.

Thanks as always Matt and Gary for helping learners even in lockdown.👍

Another great video and easy to understand. Would be good idea next time to wire up to show learners like myself. GSH tutors living legends. You guys should be awarded.

I always use a contactor these days when switching from a PIR. We had some good brand PIRs on a job but we kept loosing them every few months, and we was switching well under load, so far with a contactor they have been going well over the time they was dying. So now I will add a single way contactor in the CU if it is domestic or in an DIN rail enclosure commercially.

The relays inside was either welding shut or welding open. I have a feeling it is because we are using LED these days and well the SMPS has an inductive component and not just a resistive like a lamp does, and the PIR manufacturers have not improved there design for the new LED fixtures we are now fitting. With the above job I mentioned I am still waiting for the manufacture to come back with a reason why as they took them all back for testing.

So I just see a PIR as a control these days feeding a contactor.

Very helpful and well explained.
Thank you.

I have one of these in my front porch, its suddenly started turning on and won't go off. Then goes off for a while before coming back on all night. Do you think the sensor is just broken and needs replacing in your opinion? Sensor is clean etc.

Thanks Matt. Will part 2 show you actually wiring this with 3-core?

[chrisbluck]

Thank you for this, it's been helpful. I was wondering if you could advise me on something, I have an extension cable, running from my outside plug socket, I've connected my ground spike lights to the extension lead, I want to connect a PIR sensor to it, is there an easier way to connect it?

[REVNUMANEWBERN]

Can ANYONE direct me to a simple dependable PIR setup where I can power 5 or 10 BRIGHT outdoor lights from a 12 volt car battery?

[melvis]

very good video but still complicated because you didn't mention the color of the wiring

[michaelcostello]

All the integral PIR/Lamp do not have this over ride facility which is ridiculous. its the same with the bathroom extraction fans which do not have time delay off function. All these products should have a warning label " Expensive Rubbish ".

Superb. Thank you.
Ran into difficulties yesterday. After decorating I changed all the old sockets and switches for new MK. Nice. One of the switches controlled what I thought was an isolation switch for outside sensor light. I knew the switch was powered direct from a socket in the other room so I replaced the switch with a Fused Spur Switch 3 amp. After doing this the outside lights just stayed on. I couldn't think how the circuit had changed to make the lights stay on so decided to just switch it off and check out a few wiring diagrams here on YouTube. I can see now exactly what I've done and I need to add an override switch next to my fused spur to allow the full manual override if needed or the sensor switching the lights as required. What a dummy. 😄 Brilliant.... thanks for the vid. Problem solved.
Regards
Steve

Keep up the great videos about any tool or device or equipment specialty in these days of covid 19

For more lights than the PIR is rated for it can be used to control a contactor instead. Good video. 👍

[Ukman-england]

What colours go to the switch. Is it live brown to L1 switch what colour goes to the other part of the switch

[alliedfroth]

Cheers, just about to do this in my bathroom!

[pscustomgamer]

How’s this done with a bigger load like 8 6ft fluorescents

[dgadstv]

I've done this before... good to see this, i've used four pir to guard a store and trigger a dc alarm

I love all the videos from Matt. Keep up the great work 👍

I tried this today on a test bench. It works!
