FUNCTION
This type of system solves the problem of connecting a door phone
column in a building with two entrances, each of which equipped with
one panel and respective door unit.
In this solution, a visitor can simply press a button on either of the
two panels. The called door phone user can pick up the call and
automatically connect to the calling panel. The other panel will be cut
off.
As a consequence, it is not possible in such as system to speak to two
door units at the same time because either one or the other will be cut
off.
The user can recognise which door unit generated the call thanks to
two different call tones.
Simply press the corresponding button to release the electrical door
lock of the door unit from where the call was generated.
