4. Currently Active Decoded Alerts
Currently active decoded alerts, if any, are displayed below the Decode Activity Table. The Active event list
displays all decoded EAS alerts that are currently in progress: that is, between the start and end time for the
alert. An active event remains on the active list until it reaches its expiration time, as determined by the event end
time, or until it is updated or canceled by another event of the same type and for the same area, that redefines
the event times. The decoded alerts appear in the Current Active Decoded Alerts list as long as they are current.
Active events are moved to the expired alert list as each one reaches its end time.
Active events that are forwarded (automatically or manually) display the forwarding time as an active link label to
the
Decoder > Forwarded Alerts
Forwarded Alerts status page. Forwarded events appear on the Forwarded
Alerts status page.
Active events that are not automatically forwarded present buttons to allow review and editing,
acknowledgment, and manual forwarding / re-enable manual forwarding.
These buttons are described after
the screen shot below.
Decoder > Incoming/ Decoded Alerts web page, showing an unforwarded active alert
Acknowledge Pending Alert button
The screen shot above shows an active, unacknowledged, unforwarded alert for the active Demo alert. All
decoded alerts that have not been forwarded or acknowledged will be placed in the
unacknowledged
state. This
state is indicated on the DASDEC II front panel status LED with a steady flashing red light and within the active
alert status display by a flashing button labeled
. To end the unacknowledged state and
stop the front panel red status LED from flashing, click the flashing
button. Alternately,
you can acknowledge an alert by pressing press the front panel button once.
