|Intercommunication Table Telephone
Metallic Line, Magneto System
A magneto intercommunication system is recommended where the distances between stations are very long, or where the cables between stations are mostly run outdoor.
This type of instrument is very substantial and reliable.
A call can be received on the ringer with the switch in any position, but to answer the switch must be turned to position "A" and the micro-telephone lifted off the cradle.
NOTE - These instruments can also be used for single line and earth circuits.
