4 PIR sensors

[berginequine]

I need to wire:
- 4 PIR sensors
- to four lights
- so that when any PIR is activated all the lights come on.
- I also need a manual over-ride switch so that I can turn off the PIR sensors - and also another switch so I can overide them on.

Can anyone help me in as plain english as possible please? A diagram would also be immensely useful.

Many thanks,

B.

Start a new topic.i assume its outside.
Just run 3 core and an earth cable to all pirs

Start a new topic

Here here. It is very bad manners to hijack another's topic.

Have a reprimand

Mainly cus this one is so old and a different topic

 

[Taylortwocities]

Yes, I do wish the mods could find a way of locking any topic that is more than (say) 6 months old if there has been no activity.

But hey, maybe the question isn't important to berginequine. He hasn't started a new one, so nothing to do this afternoon except watch England v France

Ahh, hello

I am assuming these are stand-alone PIR units, and not combo PIR/lights?

For multiple PIRs, you need to run 4 core cable between the PIRs
If its outside you'll need at least rubber, or Hi-Tuf cable.

Just gang all the connections to ether like this


Live-----------------Live-----------------Live------------------Live
Neutral-------------Neutral--------------Neutral--------------Neutral
Sw.Live-------------Sw.Live-------------Sw.Live-------------Sw.Live
And the earth should be contunuous from end to end and connected to an earth terminal at each PIR, if there is one.

And for the overide ON OFF switches

PIR with overrides

Using two single pole switches to provide overrides for a basic PIR

and add the extra three PIRs and three lamps to the right hand side of the diagram


You also need to check that each PIR can switch the total load of all four lamps.

While it could be done with 4 separate mains powered PIRs, this will not be easy to control properly, since each PIR will have it's own settings for light level and time.
When one of the sensors goes bust, good luck trying to find out which one is causing the lights to stay on permanently.

Far better to just buy the equipment designed for the purpose:

Can't see a problem myself.

Sometimes it's good to have a different time for sensors.
It can give u an idea which one triggered.

A faulty one would be one that isn't clicking correctly or just disconnect 1 wire from sensor until problem goes away.

Be a good idea to buy a spare though so they would together correctly.

Thanks for the help. Sorry for "hyjacking" I am new to forums.

Agree with flame port better to fit a gjd lighting system !
