For each alarm input, you can configure an open or closed circuit to trigger an alarm and configure the
severity of the alarm. A triggered alarm generates an system message. If you enter a descriptive name
for the alarm, that name is included in the system message. A triggered alarm also turns on the LED
display (the LED is normally off, meaning no alarm). See the Cisco ME-3800X and ME 3600X Hardware
Installation Guide for information about the LEDs.
The alarm trigger setting is open or closed. If not set, the alarm is triggered when the circuit closes.
