TELEPHONE - WALL
INTERCOMMUNICATION TELEPHONE
Self-selecting wall telephone sets for dual lines

HA 200 and HA 210
Intercom telephones made from a polished walnut wall plate, produced with switches catering up to 40 stations.

The telephone consists of:-
Hanging microphone RE 6000 with cord RS 8001.
Reverser.
Push button for the release of the signal.
Bell of 100 ohm resistance.

Based on the incoming signal, the phone's bell rings regardless of which number the switch is set to. When the signal arrives, the switch is turned to the position marked A, after which calls can take place.

If you wish to talk to one of the other devices from one device, you set the switch to the number of the device in question and give a signal with the push button.

These devices can also be used for single lines. Types HA 200/10-200/20 are equipped with external clamps for the connection, in the case of types HA 210/30-210/50, the cable is connected directly to the contact pins inside the device.
