HA100
 Wall mounted Intercom telephone with woodwork of polished Walnut.

Fitted with two press buttons marked S and T and a 40ohm bell.

The HA100/15 is shown pictured to the right.

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 the users find that other conversations in progress on the network seem disturbing, the voice transmission can be improved by having the called party set the dialer to the caller's number, after which the users press the T button on their respective devices, as long as the call is ongoing. The call is then conducted on a double line.

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

Device HA 100 can be combined with device BC 1302.
