OPERATION

There are two operating states: system on standby and system active.
SYSTEM ON STANDBY
By default the telephones/monitors are inactive, so that the functions of communicating with the entrance panel and opening the door
are disabled. The entrance panels are on standby, with the audio system disabled while waiting for a call to be made or for a telephone
to activate the automatic switch-on system.
SYSTEM ACTIVE
The system changes from being on standby to being in the active state when the telephone/monitor in a dwelling receives a call from
an entrance panel or when the automatic switch-on feature is activated from one of the telephones/monitors.
Automatic switch-on feature
By picking up the receiver and pressing the automatic switch-on button of the telephone/monitor, you will be able to establish
communication with the main entrance panel of the building as well as to open the street door. Duration of automatic switch-on: 60
seconds, or until the receiver is put down or a call is made from the entrance panel.
If you have a monitor, you will also be able to see the image captured by the camera. Repeatedly pressing the automatic switch-on
button will activate this feature in each of the entrance panels of the installation. See “The Looped automatic switch-on function”.
Receiving a call
Only telephones/monitors associated to the pushbutton will receive the call. The call is confirmed at the entrance panel. If the receiver
of another telephone/monitor is picked up, beeping tones will be heard. If the receiver of the telephone/monitor is off the hook or if
no telephone/monitor is associated to that pushbutton, the panel will emit beeping tones. Time allowed to answer: 30 seconds. Maximum
conversation time: 60 seconds. Prolongation of conversation time: +60 seconds.
The panels of the other blocks will remain on standby until a call has been made. If the call is made from the external point of entry,
the entrance panel of the building where the telephone/monitor is located will be deactivated (blocked). The red light on this entrance
panel will blink during the answering and conversation periods, thereby informing any visitor that another panel is active.
