Why haven't I received an alert when the temperature has already been above the high temperature threshold for an hour?

Why haven't I received an alert when the temperature has already been above the high temperature threshold for an hour?

For units in restaurants and grocery stores an alarm will not be immediately be issued when a temperature crosses the high threshold. An alert will only be sent out if the temperature remains above the set high threshold for two hours. This two-hour delay is in place to account for defrost cycles and therefore thresholds must be set with this in mind. Sensors can be changed (by RCI) from the two-hour delay to immediate alarms for specific cases.
