General installation and operating instructions

The maximum total distance between the external unit and the furthest monitor is 400 m.
The total number of internal units with the same user code added to the number of call repetition devices connected to these internal units cannot exceed 4.
Connect only one call repetition device for each internal unit.
The MAX. cable length between the internal unit and call repetition device is 20 m. A shielded cable should be used for the connection and should not run
close to heavy inductive loads or power supply cables (230 V / 400 V).

Operation

In case of a persistent short-circuit on the bus line, the external unit emits an intermittent signalling tone.
When the visitor presses the call button, caller illumination and the internal call ringtone (if the Privacy function is not enabled) are activated and image is
displayed on the main monitor/s for approx. 60 seconds.
The maximum duration of the conversation between the external and internal units is 90 seconds.
A call confirmation tone sounds at the external unit; in systems with 2 or more entrances, if the external unit gives a busy tone instead of replicating the
ringtone, this means that another communication is already in progress with another external unit.
For programming user addresses different from the factory settings (1 and 2), see page 20.
For the intercom functions of the Bravo Kit System, see page 21.
