Relay Logic - Interlocking 4-way Electromechanical

In this illustration I demonstrate a 4-way or 4-input interlocking switch. Once a channel is actuated, the other three channels are locked out until the interlocking is reset. I apologize for the crudeness of the circuit as I only have SPDT relays in the software. Therefore several coils are tied together to create the 4PDT relays needed for the circuit.

An illustration using 4PDT relays would be awesome. Also if each fan motor had it's own reset.

Joe15355 the software currently has no multiple switch relays and so I managed to improvise using what's available. Of course you can simply imagine 4x SPDT relays in series are simply 1x 4PDT. I am not sure what you are referring to with fan motors? I illustrated each channel with an incandescent lamp and when a channel is actuated the lamp will illuminate. Only one channel can be actuated at a time and the reset button will reset the whole interlocking.
