DESCRIPTION
Intelligent intercom with “door open/intercommunicating call” push button (key), bus relay (Art. 2305) activation button (dot), “pri-
vacy ON-OFF” switch, “door open” and “privacy on” Led’s and call tone volume control (3 levels). To reduce bus current all apartment
devices are in a sleep mode when not used. In case a user forgot to replace the handset, each operation must be executed within 10
seconds of lifting the handset otherwise the handset returns to its sleep state. To then perform an operation it would be necessary
to hang up the handset and pick it up again.
