Alarm Contact
The EDS-G205-1GTXSFP has one alarm contact located on the top panel.
For detailed instructions on how to connect the alarm contact power wires
to the two middle contacts of the 6-contact terminal block connector, see
the Wiring the Alarm Contact section on page 7. A typical scenario
would be to connect the Fault circuit to a warning light located in the
control room. The light can be set up to switch on when a fault is detected.
The alarm contact has two terminals that form a Fault circuit for
connecting to an alarm system. The two wires attached to the Fault
contacts form an open circuit when (1) the switch has lost power from one
of the DC power inputs, or (2) one of the ports, for which the
corresponding PORT ALARM DIP switch is set to ON, is not properly
connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
