PIR's with LED's

[eagleeye]

I've just wired up a few new lights for a back yard at a pub and have a problem. There are 4 28 watt 2D bulkhead fittings (which i have converted to LED with the retrofit replacement LED tray) and also a 400 watt flood with PIR. I have wired the PIR's together so any one of the 3 will turn on the lights. When i switched power back on it tripped the MCB. I disconnected the live feeding the PIR on the flood and MCB stayed on but none of the other lights came on. I have 240 volt going to all PIR's but just nothing coming out.

Anyone got any ideas ?

I got all the gear from CEF. The PIR's are Challenger SL180's and the LED retrofit 2D trays are Tamlite - Infinity 2D, 12 watt.

And to be honest the LED replacement i have fitted before have not been these plug in type

Ive never wired PIRs in parallel, but if they are using a Triac to switch their load im guessing they wont like having a voltage fed into the output. Just a thought.

Don't think it'll matter. After all, they'll have the same voltage on the input side, so they'll just have no voltage across the triac.

That said, I always use a PIR with relay output for lighting.
