Filters are lists of words that you specify in order to limit the kind of alerts that a user will receive. Filter words are generally compared to the title of an alert, and also to the list of units dispatched (if given). If an alert has the title GENERAL ALERT, we will also search against the "place" name.
Filters are found under the Devices tab in your Active911 account. Click on a device to edit its associated filters.
Additionally, filters can be modified directly by the user of a given device.
To understand how filters work, you will need to consider what shift settings you have set for this device. This is because there are two filters, one for when this device is off duty, and one for when it is on duty.
The words "duty" and "shift" are used interchangeably here. The default setting for all devices is to be on duty at all times; if you have not changed this then you can safely ignore the "off duty" filter.
Filters are simply lists of words, separated by commas, that must match in order for a page to be sent to your device.
When a device is on duty, the on duty filter will limit the type of messages received. The default for on duty, when no filters are given, is to allow all messages. This means that a device will receive all alerts if it is on duty and you do not specify a filter. If you do type one or more filter words, at least one of the words must match .
Example on duty filters
fire, burn will match "HOUSE FIRE", "BURN COMPLAINT", AND "FIREHOUSE DRILL" but not "MVC INJURY" or "CARDIAC ARREST"
E231, E232 will match any call that lists E231 or E232 in the list of dispatched units
When a device is off duty, the off duty filter will be used. The on duty and off duty filters work the same way, but with one important difference: the on duty filter allows all alerts by default, but the off duty filter will block all alerts by default. This means that a blank of duty filter will not allow anything through while off duty.
