I am in need of a GCM-84211-1 I have found a site with one used module but would like one that is new or repaired. Could someone point me in the right direction toward other surplus suppliers? Also I need the default keypad access for an LCM for this sytem. I am no longer a field tech but, I'm quite sure it is the factory default because I have accessed them before a few years ago and I know I wrote it down somewhere!! but have grown OLD and forgetful.
Any Help would be greatly appreciated.
