eBay link: RARE VINTAGE 1978 FAS-12B FIRE ALARM CONTROL UNIT *TESTED, WORKING* | eBay
I wish I could get it!
It kind of reminds me of the old civil defense stuff, like the AR Timer like this one
Although this is a siren controller and that is an FACU
Man that’s cool! I wish I could buy it
If anyone has an old Gamewell Box, I would 100% trade
