Discrete Inputs and Annunciator Outputs Checkout
If the GNS 500W Series unit is connected to external annunciators/systems or external switches, perform
the following steps:

Go to the MAIN DISCRETE I/O page.
2.
For each external switch that is connected, exercise the switch and use the EXTERNAL SWITCH
STATE section to verify that the input is functioning correctly.
3.
For each annunciator output that is connected to an external system or annunciator, toggle the output
ON (corresponding box is filled/green) and OFF (corresponding box is not filled/blue) using the
DISCRETE TOGGLE field. Verify that the appropriate external annunciator illuminates when the
output is set to ON and extinguishes when the output is set to OFF. If the output is not connected to
an annunciator but provides an input to another system, verify that the other system receives the
signal.
