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.
