  • Page 7: Operating Principle Of Bus2 System

    B B B B B US2 Operating principle of BUS2 system The BUS2 door entry/video door entry system functions like a large, single-line kit. The call executed from the outdoor entry panel is directed via the 2-wire bus through the branch and floor distributors to the desired terminal, creating a single path without any further branching.
  • Page 8 The BUS2 relays have two modes of operation: - Individual: the BUS2 relay is programmed with an address (in the same way as the apartment terminals), which in this case must coincide with the terminal address from which the relay will be activated by pressing the F1 or F2 button (upon pressing F1 or F2, the terminal will send the activation command via the bus to the relay programmed with the same address).

  • Page 9: Installation And Start-Up Instructions For Bus2 Systems

    If two outdoor entry panels exist, one of them must be configured as the main panel and the other as secondary panel in order to differentiate between them. The panels have a configuration bridge for this (see section ‘BUS2 Panels’).

  • Page 10: Bus2 Panels

    BUS2 PANELS Two possibilities: - BUS2 panels: panels with BUS2 amplifier, pertaining to the BUS2 system. These are connected directly to the bus using 2 wires without polarity using the terminals (B, B) in the BUS2 amplifier. The BUS2 audio and video (colour) panels are available in the following designs and formats: - Designs: new panel Cityline (continuous profile) and Citymax (modular).

  • Page 14: City Bus2 Continuous Profile Panels

    * CITY BUS2 panel typology Aesthetically, the CITY BUS2 panels are classified in 9 series, all of which have the same width, but different heights. The new range of CITY panels enables installation on the same audio or video amplifier range thanks to the fact that the remote camera is built into the video amplifier module.

  • Page 15: Call Extension Module

    * Call extension module, ref. 2441 One of the advantages offered by the BUS2 system is that no call wires are used. This is possible because the call is made through the transmission of a digital code generated by the amplifier in the outdoor entry panel when a specific call button is pressed.

  • Page 16: City Bus2 Modular Panels

    The button modules are available with 2, 4 and 8 buttons. Calls to apartments are made by pressing the corresponding call button assigned to the apartment. - Display module and Direct keypad: Enable the compilation of Direct panels and Digital BUS2 modules.

  • Page 17: Button Module Interconnection

    As mentioned above, the modular panels do not require a call extension module, given that the button modules generate the BUS2 call code corresponding to each apartment (do not confuse the BUS call code or BUS call address with the apartment door no.).

  • Page 19 Programming the door lock-release code on Direct BUS2 panels All Direct BUS2 panel models enable the door to be opened from the outdoor entry panel by entering a 4-digit code. Below, the steps to be followed to activate and configure the door lock release using a code are shown: * Door lock-release activation sequence.

    BUS2 system enormous flexibility and service range. In addition to this, it is possible to add an ‘ADS keypad’ and ‘BUS2 display’ to the ‘4+N / BUS2 adapter’ equipment, thus significantly expanding the system’s range of services. This is done using the keypad and display functions: keypad access control, electronic directory, etc.

  • Page 24: Bus2 System Reception

    The Decoder MDS/BUS2 requires simple programming (see section ‘Decoder MDS/BUS2 Programming’). If, in addition to the reception, the BUS2 system features a BUS2 panel, the ‘BUS2 switcher, ref. 3246’ must be installed alongside the Decoder MDS/BUS2. This switcher enables the selection of and communication between the active panel/reception and the general bus, thus isolating other panels/reception or equipment which may be connected to the bus (see section ‘Basic Devices of BUS2 systems - BUS2 switcher’).

    The ‘MDS/BUS2 decoder’ acts as an interface between the BUS2 system and the MDS system, enabling the connection between the MDS reception and MDS panels in BUS2 systems, whilst extending the range of services offered by the BUS2 system: locked entrances with multiple general MDS access points, central receptions, etc.

Exit programming Note: The combination of MDS/BUS2 systems enables the creation of systems with multiple BUS2 interior blocks and MDS general entrance (various panels or reception). In this type of system, the allocation of initial and final addresses differs from the process described here. For more information on the combination of MDS and BUS2 systems, please consult the ‘MDS/BUS2 Technical Manual’.

    B B B B B US2 BUS2 SYSTEM BASIC DEVICES In addition to the outdoor entry panels and receptions, the BUS2 systems require a set of devices to route and establish communication between the panel/reception and the apartment terminals. Below, the function of each basic device within the BUS2 system is described and explained.

  • Page 30: Bus2 Switcher

    B B B B B US2 BUS2 switcher (Ref.3246) In BUS2 systems with more than 1 access (two door entry/video door entry access points or a combination of these), a ‘BUS2 switcher ref.3246’ is required. The BUS2 panel switcher is a device which connects the active panel with the general bus, isolating other panels or equipment which could be connected to the bus.

  • Page 31: Bus2 Branch Shunt

    The ‘branch shunt’ separates the BUS2 signal into various trunks (branches). The BUS2 branch shunt is a device responsible for connecting the entry panel with the branch on which the active terminal (monitor or telephone) is located, isolating the rest of the branches or systems. This shunt enables the communication of data from the remaining inactive terminals, meaning that they can communicate with the rest of the system on a data basis.

  • Page 32: Bus2 Distributors

    (monitors/telephones). The BUS2 distributor is a device which is responsible for routing the bus from the panel to the active apartment terminal (monitor/telephone), maintaining the power supply and the data signal on all monitors at all times. The distributor opens the path to the active terminal (establishing point to point contact between the panel and the active terminal) and prevents audio and video signals from reaching the rest of the branches.

In ‘call from panel’ mode, when a call is made from the entry panel, in addition to activating the BUS2 relay, the relay on the panel from which the call was made is activated (the timing of the panel amplifier relay depends on the time programmed on the panel itself).
