Acknowledging Different Alarm Types

Your system controls your building automation and system plants. Sometimes events occur (for example, a fault) that the operator must know about and that require user intervention. The alarm system processes and issues the appropriate reports (for example, to a printer) for such events.

Your system reacts automatically to a fault (for example, the ventilation plant is automatically locked during a fire alarm). An alarm is issued for a control deviation (for example, a dirty filter only triggers a simple alarm).

In both cases, the system changes to the alarm status and a corresponding alarm is issued. The system returns to normal after the cause of the alarm was eliminated and the system was reset by the operator.

Simple Alarm

Simple alarms (or alarm objects) do not require you to acknowledge or reset. Normal operations resume when the monitored condition (for example, a dirty filter) returns to normal.

Simple Alarm Behavior

Basic Alarm

More important alarms (for example, lack of water) must be acknowledged. After eliminating the cause of the alarm state and acknowledging it, the plant operations return to normal.

Basic Alarm Behavior

Extended Alarm

In the case of an extended alarm (for example, frost alarm), once the monitored state returns to the normal range, resetting will return the plant to normal. This is to ensure that important alarms are not overlooked once the alarm condition clears.
