the alarm somehow got fried and never worked again.

My guess is that after the 1234 or 9999 engineers/programming code one
step in the subsequent setup was missed because of badly written
instructions in the manual.

No, it would not set or reset with either the originally programmed or
factory codes and would not enter engineering mode at all - so no steps
could be missed. It just locked up totally and would not accept any key
entries (wouldn't even beep on each key press).

Powering off and on again gave no improvement.
