Nah .... this board has 4 leads ...... two of which (red and black) go
to the bell terminals. I think the other is a yellow that I think is
supposed to go to aux positive and a blue lead that isn't connected to
anything now .... but on the board it is labled Pgm. Then there is a
set of terminals for the relay contacts. (six terminals?)

I don't know if the PGM lead is supposed to be connected in order for
it to work .... or not. I presume that the yellow lead is supposed to
provide power for the relay board but ...... If I remember right the
PC 3000 switches negative on the bell output  and if it does .....
that means the board ..... the way it's wired now doesn't have
negative  and isn't powered until the bell rings .......   and if the
output is pulsing .......etc etc.

So I'm assuming that the person who wired it to begin with didn't know
how it was supposed to work and just left it. When I took over the
system there wasn't anything connected on the relay outputs so I don't
know why the relay was even in the panel. From what I understand Elks
941 relay does what this one is supposed to do. (per the DSC local
rep) ( but I forgot to ask him what the original DSC part number was)
So if I can get the spec's on this one .... I'll use it, if if works.
If not .... I'll get the Elk relay
