2.4 NEW ZEALAND MODE OPERATION
The RDU operates in either Australian or New Zealand mode, selected with a programmable
parameter (refer section 6.4.4.13). The differences between Australian and New Zealand
operation are listed below.
1. Display Extender Board.
This is an optional board (PA0499 or PA0742) which may be used in NZ mode and in
conjugate with a termination board provides additional outputs and inputs as follows.
Refer to section 8.4.4 for options and wiring. If a Display Extender Board is
connected then it must be enabled with a programmable parameter (system config
level 2).
NOTE - for an RDU in AS4428 mode (refer section 6.4.1.1), Trial Evac and
Silence Alarms are always associated with the Warning System and not the External
Bell.
Outputs - common normal, alarm and defect LEDs
- ancillary fire and defect outputs
- index lamp output
Inputs - silence alarms, trial evac, building services restore, lamp test,
external defect.
External Defect Input.
When this input is asserted, a fault condition is generated at the RDU. The buzzer
turns on (if the buzzer is enabled for system faults), an event is logged, and a fault
condition is signalled to the FIP. The FIP will annunciate a fault and signal Brigade
Fault.
Lamp Test.
When this input is asserted a lamp test will be initiated which tests the front panel
LEDs of the RDU, the three common LEDs and the index lamp, plus all the 16 zone
LED Display Board LEDs.
Ancillary Fire output.
This output is under control of the FIP and is turned on when a fire condition is
present. The output can be isolated - refer to section 6.4.4.3.6 ancillary
isolate/building services restore operation.
Ancillary Defect output.
This output is under control of the FIP and is turned on when a defect condition is
present or when a communications failure occurs. The output can be isolated - refer
to section 6.4.4.3.6 ancillary isolate functions/building services restore operation.
Index Lamp Output.
This output is turned on whenever the FIP index lamp is turned on or whenever the
RDU bells relay (if any) is energised.
Trial Evac Input.
The trial evac input on the Display Extender Board can be used to energise the
Warning System/Bells at the FIP or RDU and has its own set of programmable
options of pass-on, follow and local. Refer to section 6.4.4.3.7.
