Alarms and Alarm Priorities

The System Manager and Zone Coordinator monitor the status of equipment on the network and report an alarm whenever they detect a problem has occurred such as an offline condition. The following information is gathered for each alarm:

•Name of the device the alarm is associated with

•Alarm condition

•Date and time when the condition occurred

•Suggested user action

•Priority of alarm, which can be one of the following:

•Service - service whenever convenient

•Service Priority - service is required as soon as possible

•Critical - service is required immediately

Types of Alarms

The Zone Coordinator generates an alarm for each new problem condition, such as:

•Offline transitions of the COB or VAV Rooftop Unit (RTU) Controller, Bypass Damper Controller and Zone Controllers on its Zone Bus

•Online transitions of the COB or VAV RTU Controller, Bypass Damper Controller and Zone Controllers on its Zone Bus

•Mechanical equipment problems detected by a COB or VAV RTU Controller Similarly, the System Manager generates an alarm for:

•Offline transitions of the COB or VAV RTU Controller, IOM Controllers and Coordinators on its System Bus

•Online transitions of the COB or VAV RTU Controller, IOM Controllers and Coordinators on its System Bus

•Mechanical equipment problems detected by a CV RTU, COB RTU or VAV RTU Controller
