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.
