Help! I am looking for a PROGRAMMING manual for the Kidde/Thorne (from the 1980’s) and now called Grinnell fire alarm panel Model KDR-1000 and have not found a copy. I have seen the instruction/installation sheet and specs but our electrician needs more. I have already contacted Kidde without success; Thorne is no longer in business. Before I contact Grinnell, I thought ask here. Any suggestions?
