Well because it looks pretty cool in my eyes and ive always wanted an early electronic display sort of panel in my collection of ye olde burglar alarms.
I think it would be 2 for hold off and the other two for tamp return and trigger, usually an SCB module would use the bell box battery to run the bell and a SAB module uses a trigger voltage to power the bell.
Can any one help me with identifying a few of these terminals on this old ADT box.
PID and anti drill.
Also does the tube markings mean i can have an extra xenon tube for an inside flash if someone were to get inside the box?
