An Alert Rule has several Alert Types that specify what conditions generate alerts. When a Bell Controller 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.
Alert is activated when a Bell Controller has not checked-in to OneVue for more than 3 hours. A bell controller is scheduled to check-in hourly.
Time Sync Failure
Alert is activated when the Bell Controller fails to receive time from its NTP time source during its last check-in. During this condition, it may not have the correct time that can impact the accuracy of your bell schedules.
Bell Controller battery power is for backup-power use only. An alert is activated if a bell controller is operating on battery backup power only and a low battery level is transmitted during its last check-in. When operating solely on battery backup, its estimated battery life is up to a maximum of 24 hours. The device's batteries should be replaced during this alerting condition to avoid a loss of data.
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.
