After 30 years of reliable operation, the keypad connected to our DSS-670 suddenly started flashing one or more lights and beeping randomly. All the keypad lights dimmed. I had to remove power to stop the beeping and flashing.

Four days. Sounds about right. Check the output voltage on the battery leads. Then check your fuses.
I think that's an old Brinks made by Scantronics. (Well something like that comes to mind, but I never worked on those antiques.) Programmer needed for anything else most likely. The one guy who used to provide that kind of support is out of the business. Sold all his stuff that was left a number of years ago. Last I heard he was planning to manufacture plastic shredding machines.
