RADIO ANTENNAS
If the EAS device is equipped with internal radio receivers, there will be industry
standard F-type connectors for each receiver (up to three total). Review your states’
Emergency Alert System Plan for the appropriate monitoring assignments; these
assignments will assist in determining the proper antenna for the frequencies that
need to be monitored.
The EAS device’s internal radios are designed to receive the following frequencies:
Band Frequencies
FM 87.9 - 107.9 MHz
NOAA 162.440 - 162.550 MHz
AM 530 - 1700 KHz
For proper recepon, use a good quality, shielded RG6 coaxial cable and connectors.
The quality of the incoming audio signal will aect the operaon of the audio decoders,
and the quality of the forwarded audio messages.
AUDIO WIRING
The One-Net and DASDEC plaorms have two types of analog audio: EAS Audio and
Program Audio. EAS Audio Inputs feed the internal EAS decoders for processing. Only
signals with EAS informaon should be directed to these inputs. EAS Audio Outputs
only send EAS decoded audio. Program Audio connecons are used for internal
switching of program audio.
Analog EAS Audio inputs are intended for line-level audio input from external radio
receivers and/or other EAS devices. These audio signals are fed to internal decoders for
EAS processing. There are numerous ways to congure the number of incoming audio
sources for decoding. To establish the best way to wire/connect the audio sources, it is
important to rst understand the origin of the incoming audio signals.
See the back panel graphic on the next page for references to specic components.
• Each audio line connector (3.5mm TRS) supports two EAS decoders. The le side of
the input is decoded separately from the right side.
• The Main Audio – Line 1 & 2 inputs (10) are disabled if internal radio receivers are
being used for Main Audio L1 & L2.
• When Radio 3 is in use, the Auxiliary Audio 4 (terminal block) input (1) is ulized
for a line-level input (Auxiliary Audio 1 R2).
• For conguraons where only two internal radios are being used (Main Audio L1
and R1), ulize the Auxiliary Audio – Line Input 3 & 4 (8) for line-level audio.
• The EAS Audio Out (9) can be used to monitor radio receivers, selecvely play out
stored EAS alert messages, and play out acve EAS alert messages. This output is
intended for audio monitoring, feeding audio to other EAS devices, and feeding
audio to the oponal MPEG card.
