SYSTEM DESCRIPTION

RDU Mk2 Installation & Programming Manual Document No: LT0499
System Description
Page 2-2 8 April 2015 Issue 1.02
2.1 OVERVIEW
2.1.1 GENERAL
The RDU is an intelligent Remote Display Unit (RDU) which performs the functions of a Fire
Fighter's Facility (FF) as specified by the Australian Standard AS4428.1 for Australian use
and NZS4512 for New Zealand use. It can connect to any of MX1, F3200, F4000 or
MX4428, FP1600 Mk3 and Sigma 5 FIPs to provide remote indication of zone status and
optionally control the FIP. Up to 8 RDUs (in "reply" mode) can be multi-drop connected to
the FIP, with additional devices connected in "listen only/mimic mode" if necessary.
The operator menus and programming of RDU Mk2 V5.00 software are quite different to the
RDU Mk1 software V1.00 to V2.12. RDU Mk2 operator and programming menus are now
similar to the NDU and includes new features such as temporary password access, non-
volatile history, downloadable firmware and Tandem LCD access.
RDU configuration programming can be used to select which zones the RDU displays and
allows control of. This means that in multiple RDU systems, each RDU can be assigned the
zones corresponding to its own particular area. An RDU can be programmed to simply
mimic the FIP zone status and alarms, or it can be programmed to allow control as well,
where zones can be acknowledged, reset or isolated from the RDU.
The RDU can have its own independent set of zone names (which may be different from
those at the FIP) or it can use the zone names sent by the FIP. The RDU can have up to 33
sixteen-zone LED display/relay boards fitted.
The RDU is supplied in several different physical arrangements, including cabinet (with MAF
board), slimline wall mount, and slimline flush, as shown in Figures 2.1.1, 2.1.2 and 2.1.3.
It is available in 8U and 15U cabinets complete with a MAF/PSU module and Manual Call
Point MCP. There is space for mounting from four to ten 16 Zone LED Display Boards as an
optional extra.
The slimline RDU is a much smaller, minimally configured RDU. It is a wall mounting, low
profile 4U, 177H, 450W, 50mmD unit which is line powered from the FIP. It does not have a
MAF/PSU module and there is no provision for internal mounting of 16 Zone LED Display
boards or a Manual Call Point MCP. 16 Zone LED Display boards and a MCP can be
connected externally, if required, providing suitable provision can be made for physical
mounting, e.g., extender cabinet plus the extra power required to drive the LEDs. A flush
mounting version is also available.
The RDU may be used in either Australian mode or New Zealand mode and this manual
describes the configuration for both modes. The differences between Australian and New
Zealand configuration are described throughout this manual and are listed in section 2.4.
The country mode is selected with a programmable parameter.
2.1.2 DISPLAYS
The primary display of the RDU is a 2 line by 40 character LCD on which status messages
and prompts are shown. The LCD has backlight illumination which is turned on when there
is an alarm or operator interaction.
Common conditions ALARM, FAULT and ISOLATE, and various system states are
displayed on LEDs adjacent to the LCD.

Document No: LT0499 RDU Mk2 Installation & Programming Manual
System Description
Issue 1.02 8 April 2015 Page 2-3
The AS1603.4 series display panel composed of the LCD, LEDs and operator keypad meets
the requirements of AS4050 (int) for a Fire Fighter's Facility (FF).
The AS4428.1 series have a keyboard layout and operation complying with AS4428.1.
As an optional extra, individual zone status (ALARM, ISOLATE and FAULT) can be
displayed on LEDs by fitting the appropriate number of 16 Zone LED Display boards. The 3
column 16 Zone LED Display boards include as standard, an open collector transistor output
for each zone which can be used to drive an internal or remote mimic display.
For New Zealand mode, an optional Display Extender Board may be fitted and is connected
at the end of the 16 zone LED display board chain and provides 3 common status LEDs and
some supplementary inputs and outputs.
2.1.3 SERIAL COMMUNICATIONS PORT
An RZDU port is included in the RDU to provide the 3 wire or 4 wire link required for
connection to the FIP.
2.1.4 PRINTER/PROGRAMMER PORT
The RDU also has an RS232 serial port to drive a logging printer, which records all events,
time and date stamped as they occur. This port can also be used to save or load the
programmed database (refer to section 6.3.5).
2.1.5 FP0558/FP0585 (785/786) : MAF-CONFIGURED RDU ONLY
2.1.5.1 MAF OUTPUTS
A MAF-configured RDU provides 7 relays as standard on the MAF/PSU module. These can
be used to switch alarm bells and ancillary equipment such as door holders, air-conditioning
shutdown, etc. The MAF standby, alarm, fault and isolate relays should not be used for
signalling to the brigade, the brigade connection should be made to the FIP.
Each zone can be programmed to operate these relays when the appropriate condition is
present, e.g., Alarm, Fault, Isolate, etc.
2.1.5.2 POWER SUPPLY
The MAF configured RDU has a 3 Amp battery charger/power supply as standard. There is
adequate room for large batteries.
An optional 6 Amp battery charger/power supply is available.
Fuse protected battery backed and non-battery backed supplies are available to power
external loads such as bells, illuminated signs, interposing relays, gas release solenoids,
door holders, etc.

2.2 PHYSICAL STRUCTURE
2.2.1 FP0558/FP0585 (AS1603.4) & FP0785/FP0786 (AS4428.1) MAF CONFIGURED
RDU
The MAF RDU has a rugged, lockable painted steel cabinet, which houses 19 inch rack-
mount equipment of up to 8U or 15U height (667mm). It comes complete with a MAF/PSU
module mounted in the cabinet and room for batteries below. Refer to Figure 2.2.1.
8U cabinet versions are available as FP0585 (FP0786).
The Operator Display has a screened, polyester overlay mounted on a hinged inner door
fitted to the top 4U position. The Controller/Display PCB mounts directly to the rear of this
door.
The remaining space is covered by a blanking plate, but there is provision for mounting other
equipment below the Operator Display. E.g., a 7U hinged inner door for a mimic, or to
mount the 16 Zone LED Display boards, may be fitted directly below the Operator Display.
There is provision for mounting equipment in the bottom 4U (e.g. an AS1668 control rack)
but this could encroach on battery space.
The outer door has an MCP (Australian panels only - not NZ) on the outside and a large
acrylic window to allow viewing of the equipment inside.
For New Zealand operation the display extender board, unprotected termination board and
optional brigade key-switches could be mounted in the 15U cabinet or a suitable external
cabinet. Refer to section 8.4.
2.2.2 FP0559 (AS1603.4) / FP0787 (AS4428.1) SLIMLINE RDU
The Slimline RDU (refer to Figure 2.1.2) is a wall mounting, low profile, 177H, 450W,
50mmD unit. It is powered from the FIP via the +24 and 0 volt wires of the 4 wire cable that
is terminated onto the 1931-27 Remote Interface board inside the RDU. It is intended as a
small stand-alone unit that allows remote indication and operation –but no MAF facility.
For New Zealand operation an external cabinet could be provided to house a Display
Extender Board and any 16 Zone LED Display boards.
2.2.3 FP0772 (AS1603.4) / FP0788 (AS4428.1) FLUSH SLIMLINE RDU
The Flush Slimline RDU (refer to Figure 2.1.3) is a flush mounted "slimline" RDU and has

FIG 2.3.1
SYSTEM STRUCTURE: MAF CONFIGURED RDU
2.3.2 INTER-CONNECTION & STRUCTURE –MAF CONFIGURED RDU
A basic MAF Configured RDU system has one Controller/Display and one MAF/PSU,
interconnected by Flat Ribbon Cable (FRC), as shown in Fig 2.3.1. For New Zealand
operation, a Display Extender Board is normally also used.
2.3.2.1 16 Zone LED Display Boards
16 Zone LED Display boards are driven from the "LED DISPLAY" serial bus on the
Controller/Display PCB. They receive power from the MAF/PSU via two power leads.
Where more than one is required they are connected in series from right to left (as viewed
from the front) on the RDU. The 34 way FRC from J13 of the Controller goes to J1 ("From
Previous") of the right hand Display Bd. Zone 1 (default) corresponds to the top LEDs on
the left hand Display Bd.
There are two types of 16 zone display boards. One type has two columns of LEDs, the
other type has three columns. For the three column type, the last board requires the "end of
bus" mini-jump connector, (link LK1), to be fitted. Up to four 3 column boards or ten 2
column boards can mount internally. Additional Display boards can be mounted externally,
up to 33 in total, to provide individual zone status indication for all 528 zones. The additional
loading due to extra Display boards will need to be carefully considered when planning the
system battery/PSU configuration. Refer to section 5.3.
LED Display boards may also annunciate FIP Relay status, i.e., Alarm = relay activated,
Isolated = relay isolated, Fault = relay wiring fault (i.e., supervision fault). The default is that
status information as received from the FIP is treated as zone status information at the RDU.
If relay status information is to be processed correctly then the RDU must be specifically
programmed as to which zones are relay type (refer section 7.1). Relay type zones do not
generate FF type alarm events at the RDU and alarm LEDs corresponding to relay type
zones do not flash.
The default zone to LED mapping maps zone 1 to the top row of 3 LEDs on the left most
display. Zone 2 to the row below it, etc, (top to bottom, left to right). Zone to LED mapping is
described in section 7.7.
