Viking Mobile Radio Operating Manual
Radio Wide Features
4.18 Emergency Alarm Receive Indicator
The Emergency Alarm Rx feature allows a user to receive an Emergency Alarm display
and/or alert on their radio when another radio on the same system sends out an
Emergency. This feature is supported in both P25 and SmartNet/SmartZone systems. On
SmartNet/SmartZone systems the Emergency Alarm can only be received on a radio with
the same Talkgroup as the sending radio. On P25 systems the Emergency Alarm can be
received by any radio on the same system.
When an Emergency Alarm is received the radio will either sound an alert tone, display
the sending radio’s ID or Alias, or do both depending on the settings programmed. When
received, the display context of the radio is changed to display “EA Received” on the top
line and either the ID or the Alias of the radio who sent the Emergency Alarm. If the
received ID is in the Call List, then the Alias will be displayed. If it is not, the ID will be
displayed.
An Emergency Alarm will not be received when the radio is active on a voice channel, in
Emergency, or in Radio Wide Scan Mode. Also, if in Surveillance mode, the backlight
will not turn on when an Emergency Alarm is received.
When received, the display context of the radio is changed to display “EA Received” on
the top line and either the ID or the Alias of the radio who sent the Emergency Alarm. If
the received ID is in the Call List, then the Alias will be displayed. If it is not, the ID will
be displayed.
After an Emergency Alarm has been received, any press of a button (except for the PTT)
will exit the display and clear the ten-second timer. If no buttons are pressed, the display
will continue to show “EA Received” along with the ID or Alias for ten seconds.
However, the alert tone is only heard once upon receiving the alarm. There is also a timer
that will not allow the radio to receive another Emergency Alarm from the same ID for
twenty seconds. This timer is only cleared on a channel change, zone change, or after
twenty seconds has expired.
Periodic PTT*
This trigger happens every time the user presses PTT. This trigger is
activated when the user presses the PTT button but the data will
usually be sent after the call is over. We do this to avoid delaying the
call.
Periodic Emergency*
This trigger happens every time the user puts the radio into
emergency.
Periodic Distance*
This trigger happens every time the user moves the radio a distance
defined in the Triggered-Location-Request.
* Programmable in Armada.
