The current FIS timing booklet indicates that the initial sync procedure for FIS races only, be done with a single source. ie: One of the switches in the start gate, a button either at the start or finish, or touching the wire pair together.

Our interpretation of this means that ALL of the timers need to be jumped together for the sync and the sync +1.
Then you need to disconnect the jumpers and plug the other start gate contacts and related cables back in to race.
Interesting enough this shift in requiring a single source pulse potentially takes the start gate completely out of the equation. You won't know the discrepancy between the primary and backup switches until another sync test is done prior to racing. In fact it is quite possible to forget to remove the jumper and time the whole run off one switch.
Comments please!
And of course PST has a vast selection of banana plug jumpers in a variety of colors that will allow you to jump all of your devices together.
