FUNCTION
When one of the keys of the push button panel located outside
the building is pressed, the two-tone electronic call is sent to the
loudspeaker of the matching door phone. When the handset of the
door phone called is lifted, the contact between the outside and inside
is established and the conversant can start.
To activate the electric lock, press the matching key.
Adding the Ref. 787/1 tone generator, it is possible to use the
loudspeaker of the door phone for the call from the fl oor without having
to add other buzzers. The call tone differs from that sent to the push
button panel making it possible to identify the source.
