If you have it on a bench and the loop is made up of a couple of meters of cable, the loop may be to short and resistance of the loop is not enough for the panel. 

good idea, ill try a resistor on the line

Nah nothing made any difference

When the loop is powered down this clicking doesn't happen

As above what is that output programmed as?

When there is no power on the loop the loop isolaters don't operate, i dont know gent that well have the devices you are using go isolated bases ? is one wired wrong ?

This relay

These are internal relays that are not programmable, if I understand your question

So whats its default function?

Ive tried running it with just the isolated base only (no device attached) and only a single call point

 

I think ill bin it to be honest, I dont trust it with this clicking that its doing

the isolators are in the device not the base...

the isolators are in the device not the base...

Well I did say it was the panel that was clicking

 

anyhow forget about it I'm bored looking at it

 

Thanks for the suggestions everyone that was kind enough to offer useful input.

Gent panels do click every so often its a quirk. Doesnt mean anything is wrong

After working on these panela for 10 plus years its become a white noise but its there lol
