DOOR PHONE SYSTEMS
FUNCTION
This system allows the connection of a column of video door phones
to 2 video outdoor stations with automatic switching.
When a visitor presses a call button on one of the two push button
panels, in the called apartment the bitonal electronic call is sent to the
corresponding video door phone loudspeaker and the image appears
on the screen after about 8 seconds.
During this phase, the relay box automatically inserts the relative
loudspeaking unit and TV camera, excluding the other video outdoor
station from the service.
At this point, the user sees the visitor and may respond, if desired,
lifting the handset. At the end of the call, only the electric lock of the
entrance concerned is activated pressing the key .
If, during a conversation, a call is made from the other push button
panel towards another video door phone, the fi rst will automatically
switch off and the last video door phone called will be activated. It
is not possible therefore to communicate with the 2 video outdoor
stations at the same time in that they operate alternatively and are
mutually exclusive.
