SYSTEM OPERATION
The telephone interface makes the functions of a 4+N audio door entry system compatible with a
fixed-line telephone, being possible to divert calls to the fixed-line or mobile networks.
The interface allows three types of communication:
When a call is made from the audio door entry system it will be received on the apartment's fixed-
line telephone. Audio communication with the door entry system will be established upon picking
handset up.
During communication it is possible to send the following commands using the telephone's
keypad:
“5” Door opening.
“0” Triggers the auxiliary relay used for activating auxiliary devices (bells, lights, ...).
The volume levels of the microphone and speaker can be adjusted during communication with
the audio door entry system using the telephone's keypad:
“1” Increases the audio door panel's speaker volume.
“7” Lowers the audio door panel's speaker volume.
“4” Confirms and memorises the changed volumes for the audio door panel's speaker.
“3” Increases the telephone's speaker volume.
“9” Lowers the telephone's speaker volume.
“6” Confirms and memorises the changed volumes for the telephone's speaker.
When a call is received from the telephone line during communication with the audio door entry
system, a tone from the telephone's speaker will be heard. Audio communication can be switched
between the door entry system and the telephone line call using the telephone's keypad:
“2” Switch communication to the audio door entry system.
“8” Switch communication to the telephone line call.
Depending upon its programming, the interface can differentiate between calls from the audio door
entry system and from the telephone line, selecting between 3 types of cadence.
To end communication, replace the telephone handset.
When a call is received from the audio door entry system while a telephone line call is taking
place, a tone from the telephone's speaker advising of the incoming call will be heard. The user
can switch between both calls using the telephone's keypad:
“2” Switch communication to the audio door entry system.
“8” Switch communication to the telephone line call.
During communication with the door entry system, it is possible to execute the commands
described in the “Communication with the audio door entry system” point.
To end communication, replace the telephone handset.
