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
outer dimensions of 219mm (H), 502mm (W), 75mm (D). It is otherwise the same as the
Slimline RDU.
