Had a Merlin Plus 820-D that had a bad feature module, replaced the module and everything is back up and working but the intercoms just ring busy when you try to intercom ??? Is that in the feature module ??? or program

I would guess the feature mod. The intercoms worked before they should work now. How is it with out the feature mod. Do the intercoms work.

Didn't try that,will be back in there friday and will try that, been awhile since I worked on one of these.

It's not going to function at all without a feature module. Do the ext's ringing busy have phones connected?

Is just a green light lit on control unit not red and green ?

With power off I would remove the feature module
carefully and put it back in and make sure its
fully seated and flush with back panel sometimes they are a little hinky going in.

1864, yes they do have phones connected,kenb,yes I do have agreen light,I did reinstall the feature model but I'll try it again in the morning, does it matter that the other FM was the smaller one and the new one has the busy buster,that's the only other thing that I can think of that's changed

You went from an 820d r1 to a rel 2 shouldnt make a difference.

How did you know it was a bad feature mod and not the box.

Was there any wiring done here the merlin runs on 4 pair ?

Take 2 phones and plug them directly into control unit and see if they work there.

the wiring has been in place for a "few" years, The system went down, replaced the feature modual and every thing came back up ecept the problem with the intercoms

Sorry for the misspells, watching the game at the same time, can't believe these guys, game 7 here we come :toast: :toast:

@1984: I thought certain features (at least with the 820D "breadbox" units) would work with OR without FMods...Intercom included. Perhaps this wasn't the case with the Merlin Plus units.

@DJG: I think KENB may be right regarding the box being the issue. Suppose an electrical hit took the thing out. Now suppose that the FM "did the trick" in regards to resurrecting most items. If Intercom doesn't work at this point, it's either got to be a bad FM or a good FM with bad registers on the main board (in which case, only a complete replacement will fix the problem).
