UBPSU5.0 POWER SUPPLY
The UBPSU5.0 power supply is a 5A unboxed PSU with a regulated output voltage of 13.8Vdc. There are
four fused outputs that use 20mm glass ‘quick blow’ fuses. The standard fuse rating for each output is as
follows: output1 (LED1), output 2 (LED2), output 3 (LED3) = 1A, output 4 (LED4) = 3.15A, however, these are
interchangeable so that dierent fuse values can be used providing the overall current output rating does
not exceed 5A. It also includes a battery back-up facility with a battery trickle charge fuse of 1A. The DC
output terminals and battery trickle charge terminals are independently fused.
The power supply has an inline fuseholder (with pull-up latch for easy fuse replacement) that is used to connect
230Vac mains input. The inline fuseholder also uses a 20mm glass ‘quick blow’ fuse with a current rating of
T3.15A/250V.
IMPORTANT NOTE: The 230Vac mains input terminals on this PSU should be connected to the mains supply
via a fused spur or preferably an all pole circuit breaker (refer to pages 30 - 31).
UBPSU5.0 Dimensions
Each fused output and fused battery back-up connections includes a status LED to indicate when there is a
fault with the output (when the LED is ON this indicates the output is ok, when the LED is OFF this indicates the
fuse is damaged or blown).
Terminal Connections
The battery back-up connection wires use insulated crimp connectors (red = +pos, blue = -neg) for easy
connection to a 12Vdc battery. It is recommended that a 12Vdc, 7.0Ah valve regulated lead-acid type battery
is used (Videx part no. NP7-12).

ART.893N POWER SUPPLY (for video cabinets only: 2291V, 2291V4, 2291V8 and 2291V12)
The Art.893N power supply will supply an output voltage of 20Vdc (800mA continuous or a 1A surge). It is
used to power videophones and camera modules or can be used as a ‘booster’ supply when more than 2
videophones are required in an apartment. This power supply only has an output voltage when either a
-negative trigger is applied to the -C terminal or when a +positive trigger is applied to the +C terminal. At all
other times the + and +D outputs are o. The +D is a 20Vdc output that is protected with an internal diode.
A fused spur should always be used with this type of power supply. It is contained in a standard 9 module A
type DIN box for mounting on a standard DIN rail.
IMPORTANT NOTE: The 230Vac mains input terminals on this PSU should be connected to the mains supply
via a fused spur or preferably an all pole circuit breaker (refer to pages 29 - 30).

Art.701T BST/GMT Time Clock
The Art.701T is a digital time clock with BST/GMT automatic correction, back lit LCD display and trade button
input. The time clock is already pre-wired within the cabinet from one of the 13.8Vdc fused outputs on the
UBPSU5.0 PSU. It incorporates a dry contact 3A rated relay (CO, NO and NC).
Includes six fully programmable ON/OFF times, they can be set for a single day of the week (Mon - Sun),
weekends (WE), week days (WD) or all days (AD). To disable an ON/OFF time simply set the ON time the same
as the OFF time. In the event of a power failure the on board battery back-up will maintain the correct time
and all the time bands that have been setup.
Programming and setup of the time clock is carried out by using the four push buttons: MODE, UP, DOWN
and SELECT (on/o) just below the LCD display and the two internal jumpers JP1 and JP2. The MODE button
advances through the dierent programming modes starting with mode 1 which allows the editing of the
time and date. Modes 2 – 7 allows the editing of the time bands. Mode 8 allows the editing of the relay time
in trade mode only (mode 8 will only appear on the display when the time clock is in trade mode this is done by
setting jumper JP1 in the A position, also see notes below). The UP, DOWN buttons allow the information to
be edited and the SELECT (on/o) button moves the cursor to the next input eld on the display (refer to
the programming ow chart on page 14). If the time clock is inadvertently left in programming mode it will
automatically revert to standby mode after a preset time.
Jumper JP1 sets the time clock in either trade mode (JP1 in position A) or time clock mode (JP1 in position
B). When in trade mode the on board relay is only triggered when the terminal inputs TR and - (connected
directly to a trade button on the intercom door panel) are shorted together. The on board relay will trigger
for the relay time set in mode 8 and will only be active during the time band/bands (6 programmable time
bands 1 - 6 are available) setup in modes 2 - 7. When in time clock mode the on board relay is automatically
triggered when the time clock enters the time band/bands set up in mode 2 - 7.The on board relay will switch
from NO (normally open) to NC (normally closed). Once the time clock reaches the end of the time period it
will switch back from NC to NO. When the jumper JP1 is set to position B mode 8 will not be available in the
programming menu.
Programming Modes
Jumpers JP1 and JP2
Jumper JP2 enables or disables the time clock’s BST/GMT correction feature. When JP2 is in position A the
automatic British Summer Time correction feature is disabled. When JP2 is in position B the automatic British
Summer Time correction feature is enabled (the default position for JP2 is set to the B position).

VX123-A / VX123-V AUDIO AND VIDEO 4 DOOR SWITCHING CARDS
Audio cabinets will include a VX123-A 4 door audio switching card and video cabinets will include the
VX123-V 4 door video switching card.
Each switching card requires 12Vdc power and will be pre-wired from one of the 12Vdc outputs on the
UBPSU5.0 psu. It has four fused (tted with a 1A, 20mm ‘quick blow’ fuse) door input/output terminals that
includes a status LED to indicate when there is a fault with the input/output (when the LED is ON this indicates
the input is ok, when the LED is OFF this indicates the fuse is damaged or blown). Each set of door input/output
terminals include connections for the following:
• 12Vdc/GND power output to power each door panel (fused connection on 12Vdc terminal).
• L/- databus connections from each door panel (common ‘through’ connection).
• Busy connection from each door panel (common ‘through’ connection).
• Trade output to each door panel (common ‘through’ connection).
and for the VX123-V video switching card three additional terminal connections:
• SL switching signal from the door panel to switch the V1/V2 balanced video signal through the
corresponding door input/output position on the switching card.
• V1/V2 balanced video input signal connection from door panels camera module (switched connections).
Also included are common output connections to connect the card to audiophones/videophones or allow
the card to be connected in series with another switching card should the system comprise of more than 4
doors (for video systems using the VX123-V three additional ‘through’ connections are included: V1, V2 and +20V).

ART.2204N 4 WAY ISOLATION CARD
Audio cabinets with isolation (2291A4, 2291A8 and 2291A12) will include 1, 2 or 3 Art.2204N 4 way isolation
cards depending on which cabinet is being used.Video cabinets with isolation (2291V4, 2291V8 and 2291V12)
will also include the Art.316I 4 way video isolation cards.
The Art.2204N will protect against shorts or faults on all connections to an apartment. Plug in connections
are used for easy maintenance. There are 10 status LED’s on each card. The green LED next to each output is
used to identify when an output is in use (green output LED indicates that the output is ON). The red LED next
to each output indicates when there is a fault on the bus connection of that output. Next to the main input
of the card is a red 12V fault LED which will indicate if there is a fault on the 12Vdc input and also a yellow S1
active LED to indicate when the S1 terminal connection is active.
The Art.2204N has a 6 way dip-switch which is used to address the isolation card (up to ID.44, output 180, refer
to the following table for addressing isolation cards). The address of the card must correspond with the address
of the audio/videophone in the apartment. For example, output 1 of the rst Art.2204N must be connected
to a audio/videophone with address ID.1, output 3 must be connected to a audio/videophone with address
ID.3, output 1 of the second Art.2204N must be connected to a audio/videophone with address ID.5 etc.
