Thank you for the reply...

Yes, put a 2.2k reisitor across 6 & 8 and that error should clear.

I did try a 2.2K resistor across those terminals (Fire Relay common #6
and N/O #8) earlier on when I was trying several configs to eliminate
the "Fire Bell Trouble" warning. It did not make a difference. I still
get the warning.

Without the jumper cut the realy is "wet" --it actually supplies
voltage--it is really more > of an "output" than a relay, like you are
thinking of it. If you decide to connect
something to it, use something that just wants straight voltage
(something with an internal driver).

Jumper is not yet cut---so the system will send 24VDC thru those
terminals upon a fire alarm? If there is a siren driver and speaker
connected (I have an Ademco #744 with an Emer Prod Corp # 60-20, 8
ohms-20 watt "Siren Less Driver") shouldn't that satisfy the system's
need for resistence across those terminals since a resistor wouldn't.
Incidentially is that EPC device ( labeled "Siren Less Driver" )
actually a siren and not a speaker?... I guess I'm still trying to
understand the relationship between a siren driver board (i.e. the
Ademco #744) and the device that looks like a speaker. (would the EPC
device work without the Ademco cir-board?-- I'm checking the net for
specs on that device to see if it can)

THANKS again for the advice, any follow-up or further suggestions would
be helpful.
