An Alert Rule has several Alert Types that specify what conditions generate alerts. When a Monitored Asset enters an Alarm state, an alert is automatically activated and alert notifications are sent.
Alert types can be enabled or disabled and are commonly enabled based on the condition or device being monitored. By default, an Alert Rule has all alert types enabled, which OneVue only generates an alert for a condition or device being monitored.
The section below defines the alert types based on the OneVue solution and its devices.
Applies to OneVue Monitored Assets and Primex sensor devices.
-
Low Battery
Applies to: All sensor models
Alert is activated when a sensor reported a low battery level at its last check-in. Batteries should be replaced during this alerting condition. All data stored in a sensor's non-volatile memory is retained when it loses both AC and battery power.
During this condition, the Monitored Asset is in an Alarm state with a Low Battery status.
-
Temperature
Applies to: Temperature Sensor, Temperature and Humidity Sensor
Alert is activated when a Monitored Asset's last received temperature reading is either above or below its Normal Condition range and the amount of time the reading has been out of range has exceeded the time period set in its Alarm Delay setting. If its Alarm Delay setting is set to 0 (zero) an out of range reading immediately results in the Monitored Asset entering an Alarm state with the status of Out of Range, Past Alarm Delay.
During this condition, the Monitored Asset is in an Alarm state, with an Out of Range, Past Alarm Delay status.
-
Humidity
Applies to: Temperature and Humidity Sensor
Alert is activated when a Monitored Asset's last received humidity reading is either above or below its Normal Condition range and the amount of time the reading has been out of range has exceeded the time period set in its Alarm Delay setting. If its Alarm Delay setting is set to 0 (zero) an out of range reading immediately results in the Monitored Asset entering an Alarm state with the status of Out of Range, Past Alarm Delay.
During this condition, the Monitored Asset is in an Alarm state, with an Out of Range, Past Alarm Delay status.
-
Differential Pressure
Applies to: Differential Pressure Sensor
Alert is activated when a Monitored Asset's last received pressure reading is above or below its minimum range and the amount of time the reading has been out of range has exceeded the time period set in its Alarm Delay setting. If its Alarm Delay setting is set to 0 (zero) an out of range reading immediately results in the Monitored Asset entering an A
During this condition, the Monitored Asset is in an Alarm state, with an Out of Range, Past Alarm Delay status.
-
Unresponsive
Applies to: All sensor models
Alert is activated due to an Unresponsive status. The Unresponsive status indicates a check-in has not occurred within the time period set in the Unresponsive Timeout. The Unresponsive Timeout is set in the profile of the sensor gateway assigned to the Monitored Asset.
During this condition, the Monitored Asset is in an Alarm state, with an Unresponsive status.
-
No Probe
Applies to: Temperature Sensor and Water Leak Sensor
Alert is activated when a sensor assigned to a Monitored Asset has detected an enabled probe or water detector is not detected or not operating as expected.
During this condition, the Monitored Asset is in an Alarm state, with No Probe status.
-
Water Leak
Applies to: Water Leak Sensor
Alert is activated when a Monitored Asset's last reading is Wet (Out of Range) and has exceeded the time period set in its Alarm Delay setting. If its Alarm Delay setting is set to 0 (zero) an out of range reading immediately results in the asset entering an Alarm state.
-
Contact Closure
Applies to: Contact Closure Sensor
Alert is activated when a Monitored Asset's last reading is Open (Out of Range) and has exceeded the time period set in its Alarm Delay setting. If its Alarm Delay setting is set to 0 (zero) an out of range reading immediately results in the asset entering an Alarm state.
Note
In addition to alerts generated by an Alert Rule, one-time Missed Alarm or False Alarm alerts are generated when a state change is not transmitted to OneVue at the time it occurred. Commonly, a state change cannot be transmitted due to a device network connectivity issue.
