DISPLAY EXTENDER BOARD (CONTINUED)
Services Restore
When the Services Restore input is activated, the BSR logic token is set true and this can be
used in output logic to turn outputs off or on if necessary.
Trial Evac
When the Trial Evac input is activated, the Bell relay is energised and the BEL logic token is
set true regardless of any silence alarms or bells isolate condition. By default, Ancillary 3
relay is the bell relay. The Ancillary 3 relay (or any relay), can be controlled with output
logic. The TEV logic token can be used to get an output to operate when Trial Evac is
asserted, however, when outputs are controlled this way, isolation of the output overrides
Trial Evac which contravenes NZS4512. It may be necessary to program such relay outputs
as non-isolatable – refer to section 7.5 Relay outputs.
Silence Alarms
When the silence alarms input is activated, the Bell relay is de-energised and the BEL logic
token is set false unless trial evac is asserted.
Brigade Test/Brigade Isolate
These conditions share the same input and when true, result in an “abnormal” system state
(but defect is not signalled) that can be recalled with a system fault recall.
Lamp Test
This input can be used to test all the LEDs including the front panel LEDs, the LEDs on the
New Zealand Display Extender board, the index lamp and any 16 zone LED display boards.
The New Zealand Display Extender board is connected to a PA0483 termination board. The
termination board wiring connections are shown in Fig 12.2.1 below.
