JP12 on a very early SEM should be Tamper. There should be marking TAMP and COM on the PCB, it should not be unmarked. Perhaps the text is hidden in the photo. The PCB should be almost 20 years old

Yes, 20 years old is probably about right.
As you can see in the photo, there are no markings on the PCB other than \'JP12\'.

Try opening the input, see if there is tamper alarm
