one extractor for two circuits

[romani]

Hi people

Just wondering anyone can explain me how to wire one inline extractor (vent axia) for two bathrooms. This extractor has only one switched line input. Fan should start witch lights (lights in one bathroom only).
I've seen this configuration one day , I coudn't figure out how it works (I think intermediate switch was used)

thanks for any advice

hope I've posted in right place

Think you need to use a couple of relays so as if 1 light activates the fan comes on and 2nd light remains off and vice verca.

You can do it with douple pole switches

Use one side of the pull cord as a normal 1 way switch
From the switched (load) side of those wires feed the other side of the double pole switch with a loop of wire,then from that load side feed the fan
Do the same with the other pull cord in the other room
So in effect at the fan you will have two switched feeds
They cannot back feed to the light of the other room,as long as they are on the same supply it works ok
Two pull cords will be easy and cheap
