MONITOR FEATURES IN B-FAST SYSTEM
CALLS RECEPTION AND 'VIDEO TRANSFER' FUNCTION
When a call is received, the user monitor rings with the programmed tone, for the following times:
Call origin
Call from main door unit
Call from secondary door unit
Intercom call
Floor call
When the door phone or video door phone call is received, it is always possible to activate the door unit
electric lock also without activating the communication. If in the apartment there are several monitors in
parallel (max. 4), the internal codes 0 and 1 will immediately ring and immediately afterwards will ring the
internal codes 2 and 3. The user internal code 0 also performs the monitor power-on.
In this case, during all the off-hook waiting time (60s before the communication becomes active), the other
internal codes can turn their monitors on by pressing the auto-on button "•" ('video transfer function') until
the communication of a called user monitor is activated. With audio on, the image will be displayed only on
the monitor that is in communication. Therefore the camera image will always be displayed on one monitor
at a time.
AUTO-ON FUNCTION
If the monitor is in standby mode and audio is not active, it is possible to perform an auto-on function on the
'Master' unit by pressing the button "•" (see door units performances). Press the audio button (3) to establish
a communication with the Master door unit. Besides the user can command the door opening at any time with
the button 1.

AUTOMATIC DOOR LOCK RELEASE FUNCTION
This feature can be activated/deactivated with the dedicated button C. If the function is activated, the red led

in parallel, connect this button to internal code 0 only. The internal codes 0 and 1 immediately ring and
immediately afterwards ring the internal codes 2 and 3.
MAIN DOOR UNIT OPEN DOOR FUNCTION
If on the "Main" door unit is connected a door detector on SAP/0 terminal pins, the monitors can display the
physical state of that door. When the door is open, the light present in the door opener button (8) will turn
on red.

The monitor is provided with an output command on the terminal pins pair (S-, S+) to activate an additional
ringer or a relay. The output is activated when any call tone is generated.
