New Zealand Operation

12.4 PROGRAMMABLE OPTIONS
There are a number of parameters that need to be set for New Zealand operation according
to the installation requirements. These are detailed below.
Fig 6.1.2D2 shows that they are accessed by selecting option 3:Global data, then 5:more,
4:more, 4:more, then 4: New Zealand options.
A database re-initialise will select New Zealand mode by default if a New Zealand Display
Extender board is fitted. If a New Zealand Display Extender board is not fitted, New Zealand
mode must be programmed manually.
New Zealand Mode Programmable Parameters
1. New Zealand mode – enable/disable
When this parameter is enabled, the user is asked whether a number of other
parameters (detailed below) should automatically set to their New Zealand mode
settings. When this parameter is changed from enabled to disabled, the values of a
number of parameters are set back to non-New Zealand mode settings.
2. New Zealand Display Extender board fitted – Y/N
If a New Zealand Display Extender board is fitted, this should be set to Y.
3. Battery Very Low = Alarm – Y/N
If this is enabled, a brigade alarm will be signalled on power-up or whenever the supply
voltage reaches the battery very low threshold. The bells are not activated for this alarm.
4. Evac Defect is fault – Y/N
External defect is fault – Y/N
These two parameters select whether the corresponding input on the New Zealand
Display Extender will result in a defect (fault) being signalled when the input is asserted.
If sent to N then the input is available as a general purpose input, the state of which can
be accessed using the logic tokens NEV and NED respectively.
5. Battery testing & monitoring
There are four parameters, that for an NDU with no MAF board only the battery low
monitor parameter needs to be set – the others are “don’t care”.
(a) Battery low monitor – enable/disable
For an NDU with a MAF board, this should be enabled. If enabled, then when the
supply voltage falls below the battery low threshold a defect will be signalled.
For an NDU with no MAF board, if this option is enabled then a defect is signalled
when the supply voltage falls to the battery very low threshold.
(b) Battery connection check – enable/disable
This is enabled by default. When enabled, the battery connection is checked every
28 seconds by reducing the charger voltage for 500 milliseconds and monitoring the
battery voltage.
(c) Hourly battery test
This is disabled by default and is not required for New Zealand operation. When
enabled, every hour the charger voltage is reduced for 60 seconds to check the
battery voltage.
