I'm hoping someone can identify a year for this system......on this site it's mentioned the first keypad was used in the 80's and the second keypad was used in the 90's.
I'm curious as I have a takeover to do, obviously with a new panel and keypad at the very least, and haven't seen one of these systems (not a lot of Brinks panels around here). The panel looks nearly identical except it also includes a list of parts Brinks would want back in the event of time travel. The keypad he has is the 90's version as above, only much more yellowed and ready for a dumpster.
Just to add to the fun, apparently this system was also taken over by ADT at some point. Not sure how they re-programmed it???
