melco MC-9 manual sought.

Babybearjs:
does anyone have a copy of the Melco MC-9 9 station ICM module manual available? making the connections is pretty easy except for terminal: "PC" and "AUD SUP" I'm not sure what these are for.... 

poplar1:
AUD SUP is for whichever ringing source you are using for your intercom: 10 Volts AC for the newer buzzers, 18 VAC for the old Edwards Buzzers, or 90VAC for ringers...

PC? I don't recall that one.


20B2:
A Battery: 24 VDC filtered (Talk path on intercom)
B Battery: 24 VDC unfiltered (for the line/hold relays or line cards)
10VAC: buzzers (intercom or common audible for outside lines)
18VAC: buzzers     "          "      "            "         "       "        "
90VAC: ringers      "          "      "            "         "       "         "

poplar1:
PC may be paging contact--you would dial one of the intercom codes and then be connected to the overhead paging system. I thought it was called something else.

BTW "AUD SUP" = AUDIBLE SUPPLY

Babybearjs:
thank you!
