2.2  Caller at the door 
The function of the Door entry system is influenced by the base setting. 
The buttons are equipped with name tags (or functions) of the people in the building. The

first column. A repeat press of the same button, in the event of a busy tone, or after

system will automatically dial the number in the second column. After a third press of 
the same button a number from the first group is dialled and so on (i.e. after busy a

up (“hang up time before repeating option”), in this instance pick a new number. 
From the System dial it is possible to control the door relay (code lock). If the caller presses 
buttons in the previously programmed combination and in a time previously set in the
