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.

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).

2.1.5.1
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.
