StatiOnS
By connecting the call buttons of a custo-
mised external door station (e.g. brass)
using the supplied cables, calls can be
sent to the DUO digital system.
Connectors
J1
IN - ALBA bus input connector from
;
previous module
J9
OUT - connector for connecting
the ALBA bus to the next board;
p1-p32 Connectors for connecting the
analogue pushbuttons (dry con-
tact) of the custom external door
station.
Installation and assembly
It is necessary to secure the
board and isolate it from enclo-
sures and metal parts to prevent
short circuits and electrical dis-
charges.
It is advisable to connect the but-
tons of the customised push-but-
ton panel only with the straps
provided, and to avoid increasing
the distance from the board.
The XT2932U adopts the data protocol
called ALBA bus and can therefore be con-
nected either to the ALBA CV2144AB (or
CA2144AB) series audio/video module (or
audio-only) or to the module group (the
audio/video part) of the HERO TD2000HE
digital keypad.
For connection to the previous module, a
6-way flat cable with two connectors and
130 mm in length is supplied. If this len-
gth is not enough, it is possible to pur-
chase article EC733 (560 mm in length).
The connection of the call buttons of the
customi push button panel is made by the
32 2-way cables, pre-terminated on one
side with the connector and with strip-
ped wires on the other side for easy con-
nection:
- each XT2932U card can be used to con-
nect a maximum of 32 analogue pu-
Mi 2593
- 4 -
shbuttons (dry contact: open/closed) of
the custom (or artistic, such as a brass)
pushbutton panel
- If the number of buttons to be connected
is greater than 32, a second card can be
connected to the first card. This allows
an additional 32 call buttons to be inter-
faced. The sum of the inputs provided by
the two XT2932U boards offers the pos-
sibility of using customi analogue call
buttons with a maximum of 64 calls in
digital DUO System systems.
Addresses associated with
buttons
No programming is required to be
performed on the XT2932U board:
The address that is associated with
the button connected to P1 of the first
XT2932U (i.e. the card that is connected
to the ALBA or HERO audio/video modules
via the J1 (IN) connector) is a consequence
of the settings of the audio/video modu-
le to which the XT2932U is connected. In
particular:
- in the case of CA2144AB/CV2144AB:
It is necessary to set the mod-
ule to call in dual button mode.
After this setting (leaving everything
else as factory configured), the but-
ton connected to input P1 will be as-
sociated with address 103, followed
by the button connected to P2 104,
and finally, the button connected to
P32 will be associated with address
135. If a second board is connected
to the OUT port of the first, the ad-
dresses will continue the previous
numbering. The button connected to
P1 will be associated with address
136 and so on, until the button as-
sociated with input P32 will be as-
signed address 168. It is possible to
change the sequence of address-
es listed above by entering the Cx-
2144AB programming and modifying
the address associated with button 1
(programming code 113). By default
this address is set to 099. If the first
Cx2144AB pushbutton, through the
programming mentioned in the pre-
vious lines, is assigned address 001,
the pushbutton connected to input
P1 of the first XT2932U will be asso-
ciated with address 005
- in case of the audio/video module of
the HERO push button panel: the ad-
dress associated with the push but-
ton connected to input P1 of the first
XT2932U is 001, 002 for P2 and so on
up to P32 to which 032 is associated.
Connecting the second XT2932U board
to the output (OUT - J9) of the first,
address 033 is associated to input P1
while 065 to input P32.
