Edit Alert Levels

*Alert levels allow the user to set warning and critical upper and lower thresholds on individual properties of a device. When these thresholds are breached an alert will be generated which will be shown on LINK Devices.

Alert levels can be set on either the Advanced Devices List or the Device Property Details whilst in EDIT mode, by selecting the property and clicking the Edit Alert Levels button

Editing Alert Levels.

Alert on Any Change will generate a WARNING alert if the value of a property is not 0. This is commonly used forON/OFF or OPEN/CLOSED switches, for example if a hatch is open.

Low Warning Level will generate a WARNING alert when the value of the property is equal to or below this value.
High Warning Level will generate a WARNING alert when the value of the property is equal to or above this value.
Low Critical Level will generate a CRITICAL alert when the value of the property is equal to or below this value.
High Critical Level will generate a CRITICAL alert when the value of the property is equal to or above this value.

*If any alert level has a value all other alert level values will be considered active including where they have been left as 0. It is advised to always add a value to all 4 alert levels.

Alert Delay adds a millisecond delay to the alert generation. This is typically used in situation where fluctuation on the alert threshold might repeatedly create and remove alerts, for example if a tank is near to the High Warning level and the vessel is moving. In this case delaying the creation of an alert by 2-4 seconds to ensure the value remains above the High Warning value could be advisable.

Repeat if still in alert after will re-request that the alert is acknowledged after a selected period of time if the alert has previously been acknowledged but the property value still remains below or above the alert level thresholds.

Bespoke messages for each alert level can be added in place of the default Low Warning Level reached, High Warning Level reached, Low Critical Level reached or High Critical Level reached

Clicking the *SAVE *button will set the alert levels. If the property value is outside of the alert level thresholds an alert will be generated on save.

Removing Alert Levels

Alert levels are removed by unsetting Alert on Any Change and setting all alert level values to 0.
