Just finished install of SK 5280 panel with remote annunciator.  Final part of job was to install annunciator to make job 100% complete and what do you know I get message on annunciator saying Key Bus Trouble.  I check all connections and wiring - no faults all seems good.  Try another annunciator and same problem.  Try direct connect at panel and still same problem.  Any suggestions?  Only odd thing is I notice a jumper clip in main panel next to terminal bus for annunciator that seems to be missing top.  Other Sk-5280 panels I check do not have this.
