5. A list of available Alarm Areas will be tabled. To assign a rule, select Edit and then select the Enable box beside the desired Alarm Area. Select Save to confirm.

The secondary purpose of an Alarm Area is to allow alarms, or other actions triggered by rule breaks, to be carried out in lanes or sections of the carriageway where they are being suppressed. By default, all alarms are suppressed for sections which are in queue. Therefore, Ignore Queues can be selected (per lane) to enable alarms during queuing in the selected lanes. However, if you wish to Ignore Queues in only specific sections, not an entire lane, then Alarm Areas can be placed over the desired sections.

AdvanceGuard® and Sea360®

In AdvanceGuard® and Sea360®, a Security Rule can include an Area Check. The areas used for an Area Check should be Alarm Areas, as an Area Check is essentially equivalent to limiting the rule to an area. See AdvanceGuard® Rules for more information.

Alarm Areas can also be used to suppress alarms in particular areas. An Alarm Exclusion Area can be created through a Track Query:

1. Perform a Track Query, in the Playback tab, and select Show on the track results in the Query Results Panel.
