Suppressing Alarms for Devices

Abstract

Check out this article and learn more details about the possibility to suppress alarms in manual or scheduled mode, in the context of specific devices.

Whenever there is a need to take a device out of the i4connected system – for example, for maintenance work – there is a potential that simply stopping the device will cause an alarm shower in the system. This results in unnecessary work for users to acknowledge/close some event occurrences that look like issues, but that really arise from the device being taken out for maintenance.

In order to avoid such situations, users having the Manage Devices permission enabled, the alarms for a Device can be suppressed for the duration of the maintenance tasks, using the Alarm Suppression feature, introduced along with version 5.6.16 of i4connected.

Suppressing Alarms in Manual mode
