he drawing below was made to help the
Modernization Elevator Mechanics in my old company wire the Ring Communication System. This system is used to
provide hands free communications between the Elevator and the Elevator Motor room and or the Security desk in the
lobby or the building office. With a press of a button the passenger can communicate with the building staff.
If you're into electronics and the building of electronic projects,
then this site,Talking Electronicsis for you. Working in the elevator field and troubleshooting electronic circuits, I found that
this site has helped me better understand the circuits I work with. See for yourself.
