Does anybody know when they made the switch from break-off tabs to clips? I was pretty surprised when I received mine that it had tabs to break off.

If I had to make a educated guess, I would say between the late 90’s and early 2000’s. (I’m making a educated guess here so don’t quote me if I’m wrong, lol)

Mind sharing the date code of your alarm and the model?

MA-12/24L. I don’t see a date code. Any idea on where it should be?
