Paging
State
Definition Result
Busy
At least one of the paging zones in
the selected Scenario is currently
being paged into through a Sce-
nario of equal or higher priority.
The user cannot page into the Scenario until
the status indicator changes to Ready (or
Caution).
Caution
At least one of the paging zones in
the selected Scenario is currently
being paged into through a Sce-
nario with a lower priority.
The user can page into the Scenario because
of its higher priority. However, the page
will override another page that is currently
occurring. If the user proceeds with the
page, the other page will stop and its pag-
ing station will display a status of Busy
Wait ....
Ready
All the zones in the selected Sce-
nario are available for receiving a
page.
The user can page into the Scenario.

How do I configure emergency paging within the HAL paging system?
The HAL System includes a special Emergency Paging Zone block that includes features specific to emer-
gency paging. Its Ducker Depth, Hold Time, and Ramp Back parameter values (which are not configurable)
are set specifically for emergency paging situations. Ducker Depth is set at its maximum depth, meaning an
emergency page essentially mutes all other audio in the zone. Hold Time, which designates the time to wait
after the page ends before beginning the ramp back process, is also set at its maximum. Ramp Back, the time
period in which the original zone audio fades back in, is set at its maximum. Another important feature is the
block's ducking of all other incoming audio, including other pages that may be occurring. Emergency paging
always has the highest priority and overrides all other pages.
Although most of this block's key parameters are not configurable (to ensure that the Emergency Paging Zone
block performs correctly in an emergency situation), you can configure and link to the block's Gain param-
eter. You may, for example, want to set the emergency page level relatively high to improve intelligibility (to
be heard over other alarms that may be sounding, and so on). And, if you want end users to have control over
the emergency page volume, you would create a control link between a DR or other remote hardware and the
block's Gain parameter.
If you want an emergency page to be heard in a specific zone, you must include an Emergency Paging Zone
block and it should be placed downstream from the relevant Zone Processor, Paging Zone, or Room Proc-
essor, preferably directly before the zone's output block, as illustrated here:
By placing it in this position, you do not have to worry about muting the zone's audio as the Emergency Pag-
ing Zone block handles this automatically. This position also ensures that other blocks will not interfere with
