Now then 'beefy', it's about time explained 'acorn'
Acorn, an alarm manufacturing company from Cornwall c1970-75 or longer?
The first control panels I ever used, both battery only & mains. They used the old 12v 'pea' bulbs as indication on the panel, still got loads of them, very useful.
Hence, acorn, so I'm not as nutty as you think! :-)
