Alarms

Overview

• The initiator (source) of the request is the device that asks another device (destination) for a summary of active alarms.
• This is primarily done from the server.
• The alarms belong to the device being queried.
• In Visual BACnet under Alarms, the destinations are the devices with alarm states (which are found in the second table).
• Warning if more than 1 GetAlarmSummary is sent during capture
• Fail if more than 8 GetAlarmSummaries are sent during capture

Why it fails

• Software misconfiguration
• Manually triggered GetAlarmSummary request
• Multiple front ends

How to fix it

• Check configuration to see how often it is asking for the GetAlarmSummary
• Set confirmed notification when alarm gets sent
• Reduce the amount of traffic on the network
• Add more routing
