BACnet Alarms

CBMS supports BACnet alarms in the following products.
  • AAC-1000 - BACnet Router and Gateway.​
  • AAC-WIN -Windows Software Bundle.
Note that BACnet alarms require a corresponding BACnet Object as a value to be monitored. For example a Modbus point could be extended with a BACnet Analog Input object and then referenced by the alarm object.

BACnet Alarms require the clock to be configured to use the correct Time Zone, on all products except Windows. To configure the time zone navigate to app-service-date to display the DateService. From this screen, change the timezone to suit your location and check to ensure that the correct time is set.
