3.4.5 NZ MODE DISPLAY EXTENDER BOARD INPUTS
The Display Extender Board is used with New Zealand operation only. The inputs it
provides are : Silence Alarms, Trial Evac, Building Services Restore, Lamp Test and
External Defect. All inputs have closure to zero volts to assert the input. An input may be
left open or unconnected if not used. Refer to section 12.8 for wiring.
All Inputs Closure below 1.5V @ 0.35mA required to activate.
Open voltage = 5V
