General Information

The DOORMASTER 4 universal adapter allows for connection of 4 existent wired door intercoms to any TK-unit, provided the existence of a A/B-interface. Already existing door stations can be connected or the TK-unit can be integrated into a multi-family-house door intercom unit.

You can connect up to 4 bell chime buttons. For every button a different dial number can be programmed. Programming is realized through a MFV-postfix which allows remote administration. On pressing the bell chime button on the door station the unit will occupy a line and dial a preset phone number consisting of 1 to 5 digits. On answering the call the extension is directly connected with the door station. A MFV-postfix activates the door opener.
