Wiring the Relay Output
The relay output alarm contacts are in the middle of the
terminal block connector as shown in the figure.
By inserting the wires and set the DIP switch to "ON", relay
output alarm will detect any port failures, and form a short
circuit. The alarm relay output is "Normal Open".
