PERFORMANCE
Suitable for small and medium door phone and
video door phone installations, the Bibus 2nd
Edition system is ideal for making new systems and
modernising old ones.
The main characteristics of the system are:
• Door phone systems can be made using only two
non-polarised wires.
• Other wires are required to make video door
phone systems.
• The system manages
alphanumeric calling stations with electronic
repertory (both main and secondary). Alphanumeric
codes can contain letter prefixes (from A to J).
• Either numeric or alphanumeric keypad modules
can be used (with dedicated alphabetic keyboard
add-on).
• Possibility of using two-row Mod. 725, Kombi and
AURA push-button panels, where the door unit,
digitiser and expansion boards can be inserted.
• Up to 18 buttons can be connected to the door unit
with digitiser. Use expansion modules connected
to the door unit by means of a flat wire to obtain
a higher number of buttons. Up to 16 buttons
can be connected to each expansion module.
Up to four expansion modules can be connected
to each door unit. Consequently, a total of 82
buttons can be managed.
• The system can manage up to 250 users.
• Conversation privacy does not require the addition
of optional devices.
• The following Bibus 2nd Edition system timing
features can be programmed by installer:
− Maximum off-hook waiting time: this is the time
elapsing from when a call is made from a
station and the called door phone handset is
picked up; the system interrupts the call after
this period of time; programmable from 10 to
40 seconds.
− Minimum conversation time: in systems with
several calling stations, this is the minimum
guaranteed time (programmable from 10 to
40 seconds) for a conversation with a calling
station before it can be interrupted by other
calls.
− Busy time: in systems with several calling
stations, this is the time during which an
external station cannot make a call because
another call or conversation is in progress at
another station; this is the sum of the off-hook
waiting time and the minimum conversation
time.

both button and/or
• The maximum conversation time without other
calls is 250 seconds.
• The electrical lock connected to the door unit or
the calling module can be operated during the
conversation. The lock operating time can be
programmed. It is controlled by a relay for button
calling units and by capacitance discharge for
calling modules.
• The system generates courtesy tones for the door
unit when a call is in progress.
• A concierge switchboard can be connected to
the system to provide the classical switchboard
performance (e.g. day mode, night mode, off,
unanswered call memory, etc.). A concierge door
phone can also be fitted in the system offering
the functions of a comfort door phone (with the
exception of call to switchboard) and can receive
calls from other apartment units.
• The switchboard can operate the door lock of all
units, both when a call is in progress and when it
is not.
• Door phone and video door phone floor calls can
be managed with different tones.
• Up to three door phones can be connected in
parallel to each user.
• Up to 250 names with an associated 4-digit door
opener code (without time limitation) and up to
eight 4-digit numeric door opener codes (disabled
by the timer contact) can be programmed for
each calling module.
• The staircase lights can be switched on and off
by means of a special decoder operated by the
door phones or the switchboard.
• Door open indication by means of LED on door
phones.
• Possibility of interfacing with a PABX switchboard
via adapter.
• The system is protected from static and pulse
electromagnetic interference. All devices comply
with CE directive in the matter of electromagnetic
compatibility.
Note: Unlike Bibus 1st Edition systems, a univocal
user code is provided so that the door phones
ONLY NEED TO BE PROGRAMMED ONCE,
also if the system includes several calling
stations. Alternatively, the door phones can be
programmed via the concierge switchboard.
