inline fan switching

[L-E_Fault]

Morning all, I have 4 toilet cubicle that all use one inline fan, each cubicle has a pir for the lighting. The customer wants the fan to come on whenever anyone enters any of the 4 cubicles. How do I wire it?

Cheers Tim

just wire it in-line with the fan...

make sure the detectors are wired in parallel, so than any one will switch it on -

A wiring Diagram Would be nice.

(To refresh OP's Memory AND for anyone else looking for one) - Get going on "Paint" Guys. :|

that would make the lights in the other cubicles come on headbang

will have to isolate tim via 4 relays. sounds alot to do but not really

just get an enclosure big enough for your choice of relay with din rail

wants to be a contactor really for contact reliability

merlin gerin do a nice contactor looks just like a mcb and mounts to din

Would DP switches do it , seperate s/wire to SL on fan , backfeed would only go as far as the other DP switches .

Edit:-

Forget the above I didn't see the PIR bit.
