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.

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.
