Send Alerts Tab
The
Send Alerts
tab is for originating different types of EAS alert messages. Only an
EAS device configured with a valid Encoder license key will display the
Send Alerts
tab.
Within this tab, there are up to three radio buttons.
Radio Button
Description
General Alerts
Originate (create and send) general EAS alert messages. Store
and recall EAS message templates.
Requires a valid Encoder
license key.
One-Button Alert
Send Required Weekly Test. Provides hyperlinks to test setup
screens.
Requires a valid Encoder license key
.
Custom Message
Originate custom EAS (CEM, ADR, and CAE) and non-EAS alert
messages.
Requires a valid Encoder and Custom Messaging
license keys.
Use the
Send Alerts
screens to originate EAS alerts (when an EAS alert is first issued
from an EAS endocder/decoder platform). EAS alert encoding is when the digital codes
and alert audio tones and message defined by the EAS protocol are assembled and
played over a broadcast medium for which EAS decoders might be listening. EAS alerts
can be constructed and issued from these web interface screens. This differs from
forwarding - when a decoded EAS alert is re-encoded and relayed.
Due to the need for immediate action during origination, Send EAS pages do NOT have
any
Accept Changes
buttons. Changes to check boxes, pull-down menus, radio buttons,
and action buttons are immediate.
Before originating any alert messages, make sure the Available FIPS and EAS codes have
been configured within the
Setup > Alert Agent™ > FIPS Groups
and
EAS Code Groups
screens. The
Configured Available Encoder FIPS Locations
and
Configured Available
Encoder EAS Codes
establish which codes are available for origination.
An EAS alert comprises a specific set of data values for encoding as Frequency Shift
Keyed (FSK) digital audio data into an audio header - creating the characteristic EAS
“squawk” sound that is repeated three times at the start of an EAS alert message. The
data placed into an EAS message is:
•
the origination code
•
the EAS code type
•
FIPS codes
•
alert duration
•
start time
•
station ID
A decoded EAS header shows these values following a standard 4 letter sequence ZCZC.
Example: a 15-minute Required Monthly Test for Genesee and Orleans, NY starting on
June 14 at 5:18PM from a station named WME would be encoded to or decoded as:
ZCZC-EAS-RMT-036037-0015-1662318-WME
.
