BLOCK 1
Introduction
The BUS2 DECODER allows the user combine MDS infrastructure on General Entrances (MDS DIGITAL NCity entry
panels) and on Interior Blocks, BUS2 equipment, panels and residential terminals.
This provides a wide range of possibilities, taking the best from each system: the multiple MDS functions (various access
points, guard unit/s, various interior blocks, greater distances .....etc) and the simplicity of a BUS2 system: UPT CAT2
twisted pair or PARALLEL Cable (based on distances and terminals). See BUS2 Technical Manual for more details.
This device is typically used to enclose various BUS2 blocks with one or various general entrances and a general guard
unit. The system within the block is entirely BUS2, and uses typical BUS2 components, while MDS elements are used
for General Entrances.
An MDS Digital central unit is used in General Entrances and digital panels with an electronic directory and/or central
guard unit are connected to it. In this case we can connect up to 10 central guard units and up to 32 panels. You can
also make use of all the additional functions an MDS Digital central unit offers: electronic directory, alarm sensors,
building automation, access control, lift control, etc....

Overview
This device has been designed to combine MDS and BUS2 Interior Blocks.
Conversations within each block are independent, they can be held simultaneously with the entry panel or the general
entrance (either of these), this is because the BUS2 Decoder also acts as an audio changer, which when in standby
mode isolates audio within the block from the general entrance allowing the interior panels (BUS2) hold independent
conversations between their various residences. In this way it is possible to maintain simultaneous conversations in
different blocks, each one with their own interior panel. When a call is made from the general entrance to one of the
block’s residences the decoder connects the audio to the general entrance. If the call from the general entrance is
directed to another block the decoder disconnects the changer in such a way that the block’s audio is isolated once
again.
The BUS2 decoder should be installed preferably where the interior block power source is installed, together with the
video switcher where applicable. It is very important to use a power source for every interior block to avoid interference
between the signals generated from one block (calls, call confirmation tones, calls to guard unit etc).
A BUS2 decoder can manage between 1 and 199 residences (maximum allowed by BUS2) depending on how it is
configured.
There can be various construction types, even within the same building.
- Type A: Individual Chalets. This is the simplest case. A BUS2 decoder is used which responds to a unique chalet
address. The decoder output is set up in parallel with the chalet’s BUS2 kit panel and the residential terminal.
- Types B, C or D. Residential Buildings There are various options depending on each building’s capacity. The logical
thing is to choose certain digits to identify the block and others for the residences within the block.
Each residence has an assigned 4 digit call code for calls from the general entrance. These digits can be assigned in
the following manner:
Call Digits No of Blocks No of residences/per block Total residences
Type A (*) VVVV 9999 (0001..9999) 9999
Type B (*) BVVV 10 (0 .. 9) 199 (001..199) 1990
Type C: BBVV 100 (00 .. 99) 99 (01 .. 99) 9900
Type D (*) BBBV 1000 (000..999) 9 (1 .. 9) 9000
B: Block Digits.
V: Residence Digits
Type A -> Individual Residences. Maximum per development: 999 chalets/residences.
Type B -> Large Blocks (more than 100 residences). Maximum per development: 10 blocks with 199
residences per block, (allows you take advantage of the BUS2 system’s maximum capacity, 199
residences in each block).
Type C -> Medium Sized Blocks. Maximum per development: 100 blocks with 99 residences per block.
The most common type.
Type D - > Small Blocks. Maximum per development: 1000 blocks with 9 residences per block.
(*) Note: these options can only be used if MDS Digital Interior Blocks are used in the system (1
Decoder per central unit). See advanced diagrams.

The conversation time between the panel and the residence is limited:
- by the "maximum conversation time" parameter on MDS panels (which can range from 10 seconds to 4 minutes).
- by the BUS2 terminals’ own time settings (which limit the maximum conversation time to 90 seconds).
The time set will be the lower of these two.
If a call is made from an interior panel and then you try to call the same block from the MDS Digital general entrance, the
MDS Digital general entrance panel will indicate that the audio line is busy, to faciliate internal communication. This time
is set as the minimum conversation time established on the MDS Digital system.
VERY IMPORTANT
Calls from BUS2 interior panels can NEVER bypass the general entrance guard unit, nor can calls be made from
these interior panels to the guard units.
The limitations inherent to the BUS2 system within each block must be kept in mind (distance, section, power
supply).
Communication cannot be established within two residences even where an MDS guard unit is used, because
the BUS2 system does not facilitate it.
The BUS2 Decoder can act as a main panel, (it allows the user programme residential terminals from the
general entrance panel/guard unit) or alternatively as a secondary panel, (allows the user to programme residential
terminals from the Interior Block’s BUS2 panel). See programming section.
When calling residential terminals from the block programmed as 0, you don’t need to key in the initial zeros.
The BUS2 decoder responds to a range of telephones which should be programmed using an starting value and
an ending value. See programming section.
1 MDS Repeater will be needed Ref. 2339 where the MDS BUS includes more than 120 BUS2 Decoders, (1
Repeater will be connected every 120 decoders).

Observations:
- All the residences in each block should be numbered from 1 upwards. Where we want the blocks to be numbered from

General Entrance will be numbered 1 0 1, 1 0 2, ... for Block 1. Then 2 0 1, 2 0 2, ... for Block 2, and so on for all the

- As there is not a BUS2 panel for each block, we can only programme the residential terminals (monitors/telephones)
from the General Entrance. See the "Programming residential terminals via the GENERAL ENTRANCE" section.
- Based on system features all the blocks would be TYPE C systems --> B B i i / B B f f, (Medium Sized Blocks, 99

Programming BUS2 residential terminals via the interior blocks’ BUS2 panel, monitors and telephones.
The programming procedure for BUS2 terminals is the same for monitors and telephones.
The residential terminals will not function if they have not been programmed
Terminal programming is carried out in 2 steps:
PROG
.
PROG
.
1.- Terminal Programming Setup:
2.- Allocation of Call Codes
Loft Telephone Loft Monitor Compact Loft Monitor iLoft Monitor
Button Panels Keypad Panels
Press the residence’s
call button
Using the keypad, enter the call code
and press the bell
A time period of 2 minutes exists
within which to carry out step 2
after terminal programming
setup.
Once this time has passed, the
terminal will exit programming
mode.
The Loft Compact and iLoft monitors have an additional function which enables monitor programming from the same
monitor, without having to carry out any operation from the outdoor entry panel.
It is recommended that each of the Interior Block’s residences are programmed from 1 upwards.
A detailed description of the features and functions corresponding to each terminal is given in the technical documentation:
Manuals available on the Fermax website: www.fermax.com.
Press the monitor programming setup button.

NOTES:
Remember that if you want to start the programming process from an MDS panel (including guard units) they
VDS decoder must have been pre-programmed as detailed under the "BUS2 Decoder Programming" section,
(Telephone 3: FFFF).
First make a call from the entry panel to any address in this block to activate the audio channel.
Telephone systems programmed with the sub-option "ANSWERED" will need one person on the entry panel and
another person to go from residence to residence. A conversation can be held between the person on the entry
panel and the residence to indicate what residence the other person is in.
Telephone systems programmed with the sub-option "SEQUENTIAL" should use consecutive numbers and just
need one person to go from residence to residence.
NOTE 1-> A message reading "press lock-release button on telephone system" will appear, but actually you
will need to press the programming button on the monitor or telephone.
NOTE 2-> The telephone’s current number will appear on the panel, or alternatively will be set to 0000 if it
hasn’t yet been programmed.
