Alarm I/O Configuration
The Alarm I/O screen supports AUX configuration of alarm input and output
conditions. It does not support mapping of alarm actions; what to do with an
alarm input, and where to source the event(s) to activate an alarm output. For
alarm action mapping, refer to 9500 MXC Node and Terminal Alarm Actions on
page 11-1.
9500 MXC Alarm I/O screen supports:
• Configuration options of:
• Inputs may be configured to sense for a high or low voltage to trigger an alarm.
• Active Condition Low requires a ground or a TTL 0v on the input to trigger
an alarm.
• Active Condition High requires an open circuit or a nominal +5V TTL
(> +2V) input to trigger an alarm.
• The output relays may be configured to be energized or de-energized on receipt
of an alarm event.
• Active Condition De-energized requires an alarm event to release the relay.
• Active Condition Energized requires an alarm event to energize the relay.
• On the relay, both normally closed and normally open contacts are available
on the I/O connector. Refer to Appendix C.
For output relay contact specifications refer to Alarm Outputs on page 3-69,
Volume II, Chapter 3.
