Description
The ZP3-RDUB1 Remote Display Unit (Repeater
Panel) mimics the status of a host ZP3 Panel at a
remote location. Bi-directional communication
between them is via the ZP3 Serial Control Bus
(SCB), which makes use of a RS485 link.
The RDU Panel has the RDU Display and RDU Zone
Boards mounted to its door. The door has cut-outs
prepared for access to push-button switches, LED’s
and the LCD. The door is closed by a Camlock. The
Controls Key can be software enabled in the host
panel to control access to the Accept, Reset, Sound
Alarms and Silence buttons.
Wiring to the RDU Panel is done through the
knock-outs situated at the back of the panel.

Installation
1. Drill holes for keyhole mounting. Distance
between screw hole centers shown below.
2. Mount the panel back box using the keyhole slots
provided.
Wiring to the RDU Panel is done through the
knock-outs on the panel back box.
Wiring Diagrams
Note: To meet noise emission standard for CE
compliance the comms wire screen must only be
connected in the panel side.
NB Do not connect the screen terminal on the
RDU panel. Connect screen on the ZP3 main panel
only! (for version 102 and greater)
ZP3AB-SCB-D Serial Control Bus Driver Board
(Z-Port 3)
This board is used to connect a number of Remote
Display Units (RDU's) and Remote Control Units
(RCU's) to a ZP3 fire panel. The hardware protocol is
a multidrop RS485 screened two-wire connection.
The wiring is connected from the ZP3AB-SCB-D
board in the ZP3 panel to the SCB connections in the
RDU and RCU panels. At the ZP3 panel, the wiring
must be terminated. This is done by connecting the
jumpers as shown below. All other panels must not
be terminated, i.e. their jumpers must be removed.
RS485 line terminations. Normal termination is on the
SCB driver, which is housed in the ZP3 panel. The
RDU is normally not terminated.
RS485 operates through up to 2000 metres of
screened twisted-pair cable. Wiring can be daisy-
chained point-to-point, or can be teed-off or spurred.
The total length of cable in the network should not
exceed 2000 metres. If the network distances are
greater than 2000 metres, then RS485 booster units,
or fibre-optic cable, should be used. Refer to the ZP-
SCB guide for more information.
The cable is specified in detail in the Ziton Wiring
Guide, but as a guideline it should be data quality
cable with a conductor size of 0.5mm
