PIR Outside lights

Hi this is my first time in this forum.
Can any one tell me the correct way to wire a bulkhead outside light with PIR. There seems to be two live terminals and one - or + terminal. do I need to put the live one side and the Neutral on the other side with the earth in the middle I have tried live and neutral but that just brings the light on and the PIR doesn't work
any offers

Hi Tres

I am not really sure what you are doing here. I think first off it will be important to know what type of electrical system you are working with for any advise. Most of the word runs AC current this would mean you would NOT have and +/- terminals in your junction. Most of the US runs two 110-120 legs and one return (common). This would give the 110/120 volts when connected to ether leg and common. If 220-240 volt were needed for such as a central AC unit it, that would be hooked up across the two live legs for a total of 220-240 volts. By carefully using a voltmeter with the range this can be verified. I believe most of Europe is the same way but they run considerably higher voltages. If you could post a link or a photo it would help me describe what I would do.

Sounds like he's trying to wire a 110v light with a burg alarm PIR... not gonna work without a relay but would be easier/cheaper to get a new 110v PIR

That may be, burglar alarms are almost all DC ( - and +). If this is the case knowitondata is right get another PIR for what you need it for. The burglar alarm type would not only need a relay but also a low voltage supply to power it.

There would be four to six terminals on a board... +,-, common, NC, and maybe NO and tamper. And you're right, 12 volts.
