Art.2306
Block exchanger
Fig.1 Fig.2
DESCRIPTION
The block exchanger is used on 2 level systems where there are main entrances that call every apartment and local block entrances that only call the
apartments within that block. One 2306 is required for each block.
The BUS line coming from the main entrance (which may be digital or traditional panels) must be connected to the BUS-M input (there are two sets of
BUS-M connections to allow the BUS-M to be connected to several 2306 units in series. BUS-O connects to the riser towards the apartments and BUS-
L connects to the local block door panels. The function of the switcher is to connect the BUS-O to either the BUS-L or the BUS-M depending on the
source of the call.
Jumpers J4 adjusts the amplification on the main bus (BUS-M). High medium and low amplification is available. Jumper J2 is an end of line jumper for
the main bus (BUS-M). This should be in the O position for all but the last 2306 (In order of connection) while on the last it should be in the C position.
The 8 way dip-switch is used to set the exchangers address (from 1 to 8 using switches 1 to 4) and the door panel type at the main entrance (digital or
traditional on switch 8). Switches 5-7 are not used at the moment. The PS connection is for the power supply which will power the exchanger and the
devices connected to it. There are two LED's for diagnostic purpose to check correct connections at the BUS-M and PS inputs.
The Art.2306 makes each block a stand-alone installation (each block may work separately but also communicate with a communal entrance(s)) Each
block may have up to 100 users and each system can have a maximum of eight blocks allowing an installation to reach up to 800 users (Note: When
using traditional main panels the limit is 80 users).
CONNECTION TERMINALS, LEDS AND JUMPERS
Terminal/Jumper Description
DIP-SW
8 Way dip switch used to set the exchanger address (switches from 1 to 4) and the main door panel type (switch 8)
J4 BUS-M input amplification (3 levels: H = High, L = Low and M = Medium)
MBL BUS Master LED: if the LED is switched OFF, disconnect the mains and reverse the wires connected at the BUS-M input –
N.B. Disconnect the link between each exchanger and starting with the one connected to the main panel(s) check
the LED. If it is off, power down and reverse the cables then connect the next exchange and repeat the LED check
until all LED's are on.
J2 BUS-M line termination (C = Closed, O = Open): when more than one exchanger is used move J2 to “C” position only on the
last exchanger in order of connection and leave the others in the “O” position.
BUS-M Main BUS input from the main entrance or from another block exchanger (Two sets on terminals for pass through connec-
tions to the next 2306)
BUS-L Local BUS input from the door panel relative to the block (or from a 2301N if the block has more than one door panel)
PS Power supply input: for blocks with 1 door panel and a maximum of 20 videophones use the Art.2321, use the Art.2321/P in
all other cases.
PSL Power Supply LED: if switched ON means the polarity is correct at the PS input (if the LED is switched OFF, disconnect
the system from the mains and reverse the connection of the wires at the PS input)
PROGRAMMING
The 8 way dip-switch enables the setting of the device address and the main door panel type selection.

When the block is set to work with a main door panel of traditional type
(4303N), switch 8 on the 4303N must be set to ON (Main entrances only).
Each block can have a maximum of 10 apartments and the range of the
addresses for each block is limited depending on the 2306 address (i.e.
the intercoms/videophones/relay connected to the block with 2306 ad-
dress 1 have apartment addresses between 1 & 10, block with 2306 ad-
dress 3 must have apartment addresses between 21 and 30 etc).

* On the digital panels connected to the main bus (BUS-M) enable the
“main” mode in the programming menu. When “main” mode is enabled the
user programming requests to enter the block address in addition to the
device (intercom/videophone/relay) address.
