1977 Acorn Alarm Panel Test - long overdue video 

Awesome!!! Great to see a new video here.

Uses a pass lock to by pass the system. Im sure that how you test it aswell. So if you open the pass lock, itll probably hold off the sounder until you lock the pass lock. That plug in the panel is for a HP1 battery. Nice to see the panel works
