Alarm Connector
The Alarm connector provides two alarm outputs that can be connected to external alarm
collection equipment. The connector also allows connection of up to two external alarm
sources, where the radio will report the status of these connections through the radio
network management. Output alarm connections are ‘Form C’ style connections,
performing alarm logic based on either Normally Opened (NO) or Normally Closed (NC)
connections compared to a Common (C) pin. Input alarm connections can be TTL logic
or NO/NC style relay closures.

Alarm Output 1 is in alarm any time that there is a traffic-impacting alarm condition
(Major). Alarm Output 2 is in alarm any time that there is an alarm that is not traffic-
impacting (Minor).
The administrator can set the polarity of the alarm inputs.
