817-USB to check if the points are programmed. If they are then
connect a fiber from the 817-USB OPTICAL OUTPUT to the display
optical connector. Connect the positive terminal of an ohm meter to
the alarm wire, and the negative terminal of the ohm meter to the
ground (green) wire. Use the inch up/down buttons on the 817 to
run the display up to test the alarms. If the purple wire is being tested
then make sure that A2, A3 and A4 are correctly programmed and
run the display from below A3 to make sure that previous bypassing
is cleared.
